Your weather station may only display some of the following increments of rain. Please refer to your User Manual for details. Here are how increments of rain are defined:

  • Rain Rate is defined as the rainfall in the last 10 minutes, multiplied by 6  (10 minutes x 6 = 1 hour). This is also referred to as instantaneous rain per hour.
  • Hourly Rain is defined as the rainfall in the last hour.
  • Rain event is defined as continuous rainand resets to zero if accumulated rainfall is less than 1 mm (0.039 in) in a 24 hour period.  Some weather stations may calculate this slightly differently and the customer should reference the User Manual.
  • Daily Rain is defined as the rainfall since midnight (00:00).
  • 24 Hour Rain is defined as the rainfall in the last 24 hours. For example, if it is currently 5:00 pm, 24 hour rain would be the amount of rain that has fallen since 5:00 pm yesterday.
  • Weekly Rain is defined as the calendar week total, and resets on Sunday morning at midnight (Sunday thru Saturday).
  • Monthly Rain is defined as the calendar month total, and resets on the first day of the Month.
  • Yearly Rain is defined as the calendar year total, and resets on the first day of the Year. The WS-1000 series weather stations allow you to change the month rain is reset to 0.00 (referred to as Rainfall Season).
  • Total Rain is defined as the running total since station was powered up.

An ultraviolet sensor (UV sensor) is a device that measures UV light from the Sun.

The UV index is an international standard measurement of how strong the ultraviolet (UV) radiation from the sun is at a particular place on a particular day. It is a scale primarily used in daily forecasts aimed at the general public.

Its purpose is to help people to effectively protect themselves from UV light, of which excessive exposure causes sunburns, eye damage such as cataracts, skin aging, and skin cancer (see the section health effects of ultraviolet light).

A UV Index reading of 0 to 2 means low danger from the sun’s UV rays for the average person.
  • Wear sunglasses on bright days.
  • If you burn easily, cover up and use broad spectrum SPF 30+ sunscreen.
  • Watch out for bright surfaces, like sand, water and snow, which reflect UV and increase exposure.

A UV Index reading of 3 to 5 means moderate risk of harm from unprotected sun exposure.

  • Stay in shade near midday when the sun is strongest.
  • If outdoors, wear protective clothing, a wide-brimmed hat, and UV-blocking sunglasses.
  • Generously apply broad spectrum SPF 30+ sunscreen every 2 hours, even on cloudy days, and after swimming or sweating.
  • Watch out for bright surfaces, like sand, water and snow, which reflect UV and increase exposure.

A UV Index reading of 6 to 7 means high risk of harm from unprotected sun exposure. Protection against skin and eye damage is needed.

  • Reduce time in the sun between 10 a.m. and 4 p.m.
  • If outdoors, seek shade and wear protective clothing, a wide-brimmed hat, and UV-blocking sunglasses.
  • Generously apply broad spectrum SPF 30+ sunscreen every 2 hours, even on cloudy days, and after swimming or sweating.
  • Watch out for bright surfaces, like sand, water and snow, which reflect UV and increase exposure.

A UV Index reading of 8 to 10 means very high risk of harm from unprotected sun exposure. Take extra precautions because unprotected skin and eyes will be damaged and can burn quickly.

  • Minimize sun exposure between 10 a.m. and 4 p.m.
  • If outdoors, seek shade and wear protective clothing, a wide-brimmed hat, and UV-blocking sunglasses.
  • Generously apply broad spectrum SPF 30+ sunscreen every 2 hours, even on cloudy days, and after swimming or sweating.
  • Watch out for bright surfaces, like sand, water and snow, which reflect UV and increase exposure.

A UV Index reading of 11 or more means extreme risk of harm from unprotected sun exposure. Take all precautions because unprotected skin and eyes can burn in minutes.

  • Try to avoid sun exposure between 10 a.m. and 4 p.m.
  • If outdoors, seek shade and wear protective clothing, a wide-brimmed hat, and UV-blocking sunglasses.
  • Generously apply broad spectrum SPF 30+ sunscreen every 2 hours, even on cloudy days, and after swimming or sweating.
  • Watch out for bright surfaces, like sand, water and snow, which reflect UV and increase exposure.

solar radiation sensor measures solar energy from the sun.

Solar radiation is radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy. The spectrum of solar radiation is close to that of a black body with a temperature of about 5800 K. About half of the radiation is in the visible short-wave part of the electromagnetic spectrum. The other half is mostly in the near-infrared part, with some in the ultraviolet part of the spectrum.

The units of measure are Watts per square meter (W/m2), Lux or Foot Candles (fc).

The device is typically used in agricultural applications, and is used in the calculation of Evapotransportation. Evapotransportation is the potential for evaporation of moisture from the soil (or the reverse of rainfall) and is a function solar energy, wind and temperature.

It will not. The device will only connect to a wifi routers main 2.4GHz signal. It will not connect to a guest account or a Mesh networks secondary nodes. To get around having to use a wifi router you can use our Observerip module which will connect directly to a router via an ethernet cable and remove the need for wifi.

Lightning sensors detect a specific radio frequency wave form generated by lightning strikes.

However, electronic devices like motors starting (HVAC units, lawn equipment), and fluorescent lighting can emit noisy electromagnetic field (EMF) signature that can generate a false positive lightning strike.

To avoid false lightning strikes, move the detector away from any electrical noise-generating devices.

Although electrical noise can be random in nature, another way to determine installation location is by using a portable AM radio set in between stations where you can hear white noise only, and hold the radio close to the installation location. Any crackling heard on the radio may be detected by the WH31L lightning detector.

The following is a guide on how to properly mount the PM2.5/PM25 sensor, and perform preventative maintenance:

Mounting Guidelines:
Place the sensor in a shaded, well ventilated, non-moisture condensing area. Although the sensor is designed for outdoor use, it is best to mount in a well protected area, such as under a patio or carport.
The solar panel is sensitive to low light, but will still require monthly charging from the USB power port.
With PM2.5 sensors, fog reflects the light, and can result in a higher reading. This is characteristic to the inherent sensor design. The condition occurs during rainy or foggy weather.
Mounting orientation is not important. It can be mounted vertically or horizontally, as long as the vents are not blocked. 

Preventive Maintenance:
Periodic cleaning of the PM2.5 sensors fan may need to be done if readings do not seem to change. To clean the fan you would remove the battery compartment of the sensor. Then carefully remove the sensor body from the protective shell. There are 2 small gauge wires connecting the solar cell to the sensor body. Please be careful to not pull on the wires and cause them to break. You would then use a can of compressed air to gently blow out any debris from the sensor fan(Warning: Do not use an air compressor)

Carefully separate the sensor body from the protective shell


ADVANCED CLEANING PROCEDURE:

(Note, if you’re not experienced/comfortable with performing something this complex please do not attempt as the unit may get damaged and void the warranty)

If an issue persists of the readings still being low then usually some pests have gotten into the internal sensor itself. You can carefully remove the screws from the main sensor housing and inspect/clean any pests, spider webs, eggs, etc. It is recommended to use Q-Tips to remove the debris.

To access the internal Detecting Chamber please refer to the images below.

Step 1: Remove the rubber coverings of the 3 screws.

Step 2: Remove the 3 screws.

Step 3: Remove the Protective Top Cover

Step 4: Carefully lift up and flip over the Sensor Board.

Step 5: Carefully clean the sensor board and Detecting Chamber then re-assemble in the reverse order.

Currently, at this time, no.

AQI is calculated individually for each pollutant. The overall pollutant with the highest AQI becomes the reported AQI. Since AmbientWeather.net only monitors (at this time) PM2.5, the only AQI value they could calculate would be the PM2.5 AQI. If, by chance, the PM10 AQI is higher than the PM2.5 AQI, then AmbientWeather.net would be reporting the wrong AQI value.

 

AQI, is a unitless index derived by the EPA.

Can the PM25/PM2.5 sensor measure pollen?

No. Pollen doesn’t have much effect on the AQI for particle pollution. Most pollen particles are much larger than the particles we measure for the AQI. The size of PM2.5 is 2.5 micrometers in diameter or smaller while pollen particles are usually well over 10 micrometers. Pollen particles can sometimes rupture and break into smaller airborne particles in the PM2.5 range, but their contribution is too small to make a difference in the AQI.

Q: What is the WIFI component power consumption for the WS-2902 series consoles?

 

A: The instant peak current of the wifi module can be up to 500mA, and its average current is about 200mA.

So it is safer to have an adapter that is capable of supplying 1.0mA ( at least 500mA ) for stable operation.

 

1000 Milliampere (mA) = 1 Watt/Volt (W/V)

This guide provides installation and mounting solutions for weather stations for home, business and industry.

Mounting Rules Of Thumb

Wind: The wind gauge should be mounted four times the distance of the differential height of the tallest obstruction, or:

Distance = 4 (Obstruction Height – Pole Height)

or

Pole Height = Obstruction Height – Distance / 4

Example 1: 
House = 20 ft tall, pole = 5′ tall. How far away from the house should I mount the pole?
Distance = 4 (20 – 5) ft = 60′ away from house.

Example 2:
House = 20 ft tall, distance = 50′. How tall should the pole be?
Pole Height = 20 – 50/4 = 7.5′

Temperature: Mount at least 5′ away from any radiation source (building, ground, vegetation, grass, rocks, etc).

North N  
North-East NE    
East E 90° (45°×2)  
South-East SE 135° (45°×3)

North-West NW 315° (45°×7)  

Weather Stations use a 16-point compass rose.

16-point compass roses are constructed by bisecting the angles of the principal winds to come up with intermediate compass points, known as half-winds, at angles of difference of 22​1⁄2°. The names of the half-winds are simply combinations of the principal winds to either side, principal then ordinal. E.g. North-northeast (NNE), East-northeast (ENE), etc.

Fog. Fog forms when the difference between air temperature and dew point is less than 2.5 °C (4.5 °F).

As an example:

Temperature = 70.0 degF

Dew Point = 65.5 degF.

Humidity = 83%

In this example, fog begins forming at 83%.

Mist.  Mist forms when the relative humidity is greater than about 70%.

Rain. Often, rain will be falling from clouds where the humidity is 100% into air with a lower humidity. For example, it can rain at a ground humidity of 60%, but over time, the humidity will increase.

High Humidity as it Relates to a Weather Station:

100% humidity is not possible as the air is completely saturated and water droplets fall out. The maximum a weather station will measure is 99%.

High (and low) humidity are very difficult to measure. The accuracy is generally guaranteed to 95% and then degrades due to the non-linearity and high gain of the capacitive sensor vs. water vapor in the air.

  9. Fixed issues with FTP functionality introduced in p01-p04.
  10. Fixed various rain rate issues occurring on Weather Underground.
  11. Fixed issues with leaf wetness, soil moisture, VantagePro and VantagePro2.
  12. Updated channel designation for multiple VantagePro and VantagePro2 sensors. Select Settings | Vantage Accessories to view these channel designations.
  13. Added “No Warnings” message if there are no current warnings from Weather Underground.
  14. p10 fixes problems introduced in p9. Not showing weather warnings on status bar.
  15. Fixed issue with cviinet.dll not loaded in system directory.
  16. If the maximum number of FTP connection error occurs, it will restart the program. You will need to set the following:
    Select Internet | FTP General Settings and select the Restart Software with Critical FTP Faultcheckbox.
  17. Fixed problems with crashing when using multiple climate site tags on your webpage.
  18. Fixed issue with Barometer (measured, raw or uncorrected) and the associated density altitude not reporting properly.
  19. Addressing issue with Rainwise data logger missing data. It may be due to updating the graphics.
  20. Fixed issue introduced in V19 with CWOP sea level barometric pressure.
  21. There is a possible issue with some data loggers and the software where communication is lost when retrieving daily highs and lows from the Davis VantagePro and VantagePro2. If you lose communication 59 minutes after the hour at specific times during the day, you can turn this feature off now. Select Settings | Vantage / WeatherLink Settings and turn OFF (uncheck) Get Highs and Lows Every Hour.
  22. Changes to strip chart time axis. Fixed autoscaling issue with y-axis introduced in Version 14.00.
  23. Added support for WMR200 / WMR200A
  24. Fixed minor issue with rate of change during archive download. Also, a small amount of data was missing between archive download and real time updates.
  25. Fixed various links in the software. Added UV and solar radiation into Wunderground. Corrected station ID in Wunderground for WMR200 and Kestrel 4500.
  26. Added feature in WMR200 regarding loss of communication. If communication is lost for more then one minute, the USB port is closed and re-opened.
  27. Added a feature that ignores bad dates in the database. Dates before 1999 and one day later then the current date are ignored.
  28. Added a out of range feature for heat index, dew point and wind chill. This out of range feature is used for all of the measured values but was missing for some of the calculated values.
  29. There was a major bug in Version p26. The database time field was not being updated. This was fixed in Version p27 but there may be some residual bad database points. These are ignored by the software, but you can edit them out by selecting Settings | Database Settings and reviewing the last several database points.
  30. P28. Another fix to the auto-scaling strip chart issue.
  31. P29. Fixed error with accumulated rain and the new WMR200. Updating WeatherHawk to the latest version.
  32. P31. Added two commands for Weather Undeground Rapid Fire command: &realtime=1&rtfreq=x.x where x.x is the update frequency in seconds. Weather Underground claims the rapid fire function does not work without this, although I could not reproduce it.
  33. P32. Working to address loss of Davis VantagePro2 communication which occurs at 59 minutes after the hour when it attempts to get the daily highs and lows.
  34. P33. Fixed issue with rain rate, hourly rain and 24 hour rain when using non-imperial units (metric and calibration gain).
  35. P34. Fixed issue with random bad WMR200 data
  36. P35. Added the option to reboot Virtual Weather Station if communication is lost from the console. Select Settings | Program Settings | Restart Program if Communication Lost for 5 minutes.
  37. P36. Addressed crashing issue with WMR100 weather station.
  38. P37. The warning tag was displaying the last warning in the list. It now displays the first warning in the list.
  39. P38. One customer could not browse using the Heavy Weather setup functions. This version allows this user to type in the path.
  40. P39. Improvement in WMR100 communiction rates. Basically, we toggled (close, open, close) the USB port after each communication. Now, we open and leave the port open unless communication is lost for one minute. This results in a much faster com rate.
  41. P40. Fixed several issues with the La Crosse weather stations, including random bad data and history text not being downloaded properly.
  42. P41. Fixed crashing problem with WMR200.
  43. P42. Software was flagging bad dates in the download state for the WMR200, but not ignoring them.
  44. P43-P44. Fixed several crashing issues
  45. P45. Added additional troubleshooting for Bad Date and WMR200.
  46. P47. There was an issue with html tags if a blank Mesomap image was entered. Addressed issue with negative temperature on TxWx.
  47. P49. Changed Hourly Rain to old method. Hourly rain is based on the rainfall in the last hour as determined by your database. If your database does not have data from one hour ago, it uses the next point in your database.
    Rain Rate is based on the rate calculated by your console and can be any variety of calculations. Please contact the manufacturer for method of calculation.
    Total Rainfall, Rate of Change is defined as the instantaneous rain rate based on the differential equation (in la place domain format)
    L(f(s)) = s / (Ts + 1), where T = 60 minutes, and transformed into the Z Domain. For more information on La Place and Z transformations, visit: http://en.wikipedia.org/wiki/Laplace_transform and http://en.wikipedia.org/wiki/Z-transform.
  48. P50. There was an error introduced in a previous version of Virtual Weather Station where it “broke” downloading archive data, which was fixed in this version.
  49. P51. Added adjustable baud rate for Peet Bros weather stations. It used to be fixed but now you can set to 2400 or 19200.
  50. P52. P51 did not have the correct DLLs attached, so I added the additional DLLs. Updated to latest VantagePro DLL. However, the baromater offset is broken in this DLL so I modified the software so that you enter your altitude and it will correct to uncorrected pressure for you in the software.
  51. P53 is a major upgrade. Adds support for WeatherLinkIP (the TCPIP version of WeatherLink). Adds adjustable timer with WMR100 and WMR200 which results in much faster updates. You must set up your communication panel again so make a note of your comport and baud rate settings before you uprade. If you are running HeavyWeather, make a note of the filepaths. If you are running Peet, check your mode switch.
    Also fixed issue with WeatherLink automation that was introduced in a previous version. Added support for RS300A and RS600A.
  52. P54. Added keep alive function that prevents lost communication for models RS300, RS600, WMR100 and WMR200.
  53. P55. Added direct USB communication for the 6510USB (as opposed to using USB to serial converter drivers). If you are having issues with operating a 6510USB in serial mode, I would recommend switching to USB mode.
  54. P56. When switching from one Vantage Pro protocal to another, it would lock up. I fixed this issue.
  55. P57. If the comport selection failed, it would revert back to Com 1. This was fixed.
  56. P58. Added functionality to add the high windspeed received from the Davis VantagePro2 into the graphs. Added troubleshooting capability for WMR200 archive data.
  57. P59. There are some reports that the WMR200A does not download all of the data to Virtual Weather Station. I have not been able to reproduce this, but I added a feature where it displays the first archived data point, the most current live reading, and the current record being downloaded, so we can troubleshoot this issue. This is under the WMR200 Sensor Communication window.
  58. P60. Continuation of the effort in P59. If you closed the WMR200 communication window and reopened, the archive records would not be updated.
  59. P61. Some users of VantagePro2 serial data loggers are reporting slow update rates or lock-ups. This occurred after the latest VantagePro DLL update. The only change for serial communication was a change in the timeout method incorporated by Davis. To test this theory, I reverted back to the old timeout method for serial communication only.
  60. P62 – P64. On some computers, the Wunderground | 5-Day Forecast panel would crash. I never figured out why but changing the number of cities from 4 to 3 eliminated the problem. The panel must be too complex to load on some computers. I hope this limitation in functionality will not hurt too many people.
    More changes to the WMR200 download archive transition state. The difficulty arises because this station sends download data and real time data at the same time and there is no flag sent by the WMR200 that tells us when the download is complete, so I used to base this on timing between the first real time record equalling the last archive record time, but due to USB buffering, the first real time record could represent old data and therefore the download record was incomplete (it would assume there were no more archive records). I fixed this by setting a 20 second timeout for the archive records. The assumption is after 20 seconds, if there are no more archive records, the software makes the assumption that there are no more records left since they usually come in 1-3 second bursts.
  61. P65. Some users are complaining that the rate of change and intergration features are not working properly. It may be an issue with clocking on the computer (which is speculation at the moment). To view the one second clocking, select Help | Internet Statusfrom the menubar. At the bottom of the panel is a one second timer update. It should be close to one second.
  62. P66. Added date check on La Crosse / Heavy Weather option. Only dates between the years 1999 and 2100 will be accepted. Otherwise, it throws out the data.
  63. P67. Solved a very random issue with the WMR200 download. It turns out that if you set the archive interval in the console to 2 minutes (as an example), it may capture data 1, 3, 5, 7, 9, .. minutes after the hour. However, if you set the database interval to 10 minutes in Virtual Weather Station, it records to the database every 0, 10, 20, 30, 40, and 50 minutes after the hour. Thus, the station archive interval and the VWS database will never “align”. This is not an issue with real time data collection since it is constantly updating. I changed the software such that it will record all archive downloads. The only drawback is your graphs will be “uneven”. In the case above, it will update every 2 minutes in the database during the archive download and every 10 minutes during real time data capture. To avoid this confusion, set your database interval and the weather station archive interval to the same value.
  64. P68. Removed popup message when VWS does not recognize HeavyWeather is running. This is now a message in the status bar. My guess is HW is crashing but it temorarily stopped VWS from continuing to read data. It will still relaunch HW.
  65. P69. There was an issue where if you selected the option to restart the software after 30 minutes of lost communication, it could restart the software over and over again if it took a while for the software shutdown to occur. Increased the HeavyWeather no sensor update status message from 1 minute to 3 minutes after startup. Sometimes it takes a few minutes for the sensor to report.
  66. P70. There was a scaling error on THWS for the VantagePro2 when non-imperial units were selected.
    Added a one second timer function. Select Help | Internet Status. If this timer is grossly in error (not reading close to 1 second), we found this to be a clocking issue with the AMD processor. This problem occurs on computers that are running an x64-based version of Windows or an x86-based (32-bit) version of Windows or when the computer has the AMD Cool’n’Quiet technology enabled in the BIOS. For more information and a workaround solution, please reference: http://ambientweather.wikispaces.com/Timing+Issues%2C+Integration+and+rate+of+changes+%28differentiation%29
  67. P71-72. Addressed WMR200 date and time issue.
  68. P73. Fixed Metar text file crashing issue.
  69. P74-75. Corrected weather station link on web pages for newer model weather stations. Fixed issue with error reporting for Davis Classic Weather Stations.
  70. P76. Correcting issues with spikes in data with WMR200A. This is caused by an errant archive record (not a problem with Virtual Weather Station, this is a problem with the data logger).
  71. P77. Some stations report separate wind gust. If this value is bad (out of range) it was not getting trapped by the Range Limits (select Settings | Range Settings). Now the sotware sets the gust limits to the same values as the wind speed limits.
    The TCPIP version of the WeatherLink data logger requires that the Virtual Weather Station stop communicating with the data logger for 5 seconds once per minute so that it will upload the data to www.WeatherLink.com
  72. P80. Fixed issue with TCPIP version of the VantagePro2 data logger. The logger requires that we toggle the TCPIP port closed and then open once per minute so the logger can talk to WeatherLink.com. However, once in a great while, the TCPIP port was in use when it tried to reopen. The software now attempts to reopen 10 times instead of only once.
  73. P81. Readdressing issues in P80. Some users are reporting lockups so added the timeout each time the port is reopened as an attempt to solve this.
    Added feature to determine what records are being downloaded from the VantagePro2 archive memory. The file is located here:
    \vws\data\vantage.txt and includes the download record header, all of the records downloaded, and any errors.
  74. P84. Fixed issue with TCPIP version of the VantagePro2 data logger. See P80. I now close and open the comport on every read cycle so the logger can talk to WeatherLink.com. In P80, there was an issue where the software would lose communication when it tried to reopen the comport, so it now tries on every read and write cycle.
  75. P85. Fixed issue with WMR968 Sensor Communication window that was broken in P84. Fixed issue with Smart Forecast not being initialized at start up.
  76. P86. Updated support for new Radio Shack 63-256 Weather Station. Updated manual to reflect new weather station.
  77. P87. Rolled revision so customer could install.
  78. P88-90. There was an issue with multiple display images popping up the first time the display is modified due to an initialization issue (fixed).
  79. P91. One specific customer mentioned FTP operation was hanging yet communication continues. I do believe this is being caused by the operating system and internet function timeouts, but I created a workaround. The program will restart in the event any operating state exceeds the Max Connect Time. To set these parameters:
    a. Select Internet | FTP General Settings and check Restart Program with Critical FTP Fault.
    b. If this time exceeds the Max Connect Time (minutes),also on this panel, the program will restart when stuck in an operating state.
  80. P92. Fixed crashing problem with WMR200.
    Fixed Columbia Weather Systems (CWS) total rain issue. With the CWS, it only calculates the daily rain and not the total rain, like other stations. For CWS, VWS now stores the total rain in the offset column of the Calibration panel (select Settings | Calibration Settingsfrom the menubar). This offset is updated on a daily basis and throughout the day is calculated by adding this offset to the current daily rain. This calcuation of total rain is then used to calculate daily, hourly and monthly rain.
  81. P93. Added functionality to determine why excessive data is being downloaded from the WMR200 weather station. The file \vws\data\wmr200archive.txt includes a time stamp for each record downloaded from archive. If you are having problems with random data being downloaded from archive memory, send me this file and I will review it. Send the file to ed@ambientweather.com for review.
    Changed the way Heavy Rain in area is reported on METAR icons.
  82. P94-95. Another stab at fixing CWS rain issue. Added functions for Rainwise and Columbia that drops out of download state if the OK flag is missed and the maximum number of download records are exceeded.
  83. P96. There has been an ongoing problem with calculating daily, monthly and yearly rain. To provide some background, most weather stations do not calculate this data, so VWS must calculate it. It is usually calculated by subtracting the daily minumum total rain from the current total rain, or:
    Daily rain = current total rain – daily minimum total rain
    The issue is that the quality of the data from the weather station may be questionable, causing a 0.00 reading in total rain, resulting the daily rain equalling the total rain, or:
    Daily rain = current total rain – 0 = current total rain
    To limit these issues and band-aid this problem, it will only calculate the daily minimum rain when the date changes. Since rain is always increasing, this is not an issue, it will always be the minimum value at midnight.
  84. P97. Addressing Columbia Weather Stations. Total rain still not correct. Also, does not stop downloading records. To troubleshoot, I added a text file \vws\data\columbia.txt that tracks some of the critical paramters for both issues. If you are having problems with random data being downloaded from archive memory, send me this file and I will review it. Send the file to ed@ambientweather.comfor review. Make sure run it for a few days and make sure rain is accumulating.
  85. P100. Supports the new Vantage Vue by Davis Instruments.
  86. P101. Added support for the Oregon Scientific EMS100.
  87. P104. Troubleshooting datbase update issues.
  88. Notice: Version P104 generates a Virtual Weather Station runtime error so I have downgraded to p101. This error occurred when I updated compilers. I have contacted our compiler manufacturer (National Instruments) to resolve this issue and they are researching it for me.
  89. Version 14.01p00. Fixed crashing issue with Version p104. New compiler caused issue
    New compiler now supports Windows 7.
  90. Version 14.01p02. Added support for La Crosse Technlogy WS-2810, as well as other newer La Crosse weather stations where the currdat.lst file is located in a different location than the Heavy Weather Executable file. For the WS-2810, I recommend deleting the file \vws\setup\config6.bin (which stores the Communication | Communication panel information) and restarting Virtual Weather Station software. Next, select the WS-2xxx seriesweather station as the weather station type.
  91. Version 14.01p03. Crashing issue was back. Found it to be the 5-Day Forecast panel. Not sure why but reduced the number of five day forecast selections from 3 to 1. Not sure if this is a windows issue or a compiler issue, because the actual code is not crashing. I apologize to those that use more than one forecast location.
  92. Version 14.01p04. Added jpeg file error notifications in status bar. One user can not determine why he an not generate jpeg files.
  93. Version 14.01p05-06. Bracketed bad dates better by only allowing downloads within 2 years of current computer or system date. Added more messages to determine why WMR200A archive downloads are sometimes incomplete, including bad data strings and CRC errors. This information is written to the file \vws\data\wmr200archive.txt.
  94. Version 14.01p07. cviinet.dll was missing in 14.01.
  95. Version 14.01p08. Crashing continues. Still appears to be related to 5 Day Forecast panel. The debugger does not give any clues so I can only point the finger at the compiler + development platform I use from National Instruments. I deleted this panel and built in from scratch, changing some of the presentation of the data. You will have to set this panel up again, which involves setting the timer, and entering your location. Sorry folks, this has been a real pain to solve.
  96. Version 14.01p10. In the latest version of Heavy Weather, they changed their executable filename and location. It used to always be located here:
    c:\progam files\HeavyWeather\Heavy Weather.exe, so all the user had to do was browse to the directory. Now I have the user find the actual file instead of the directory. If you need to correct this, Under Communication | Communication, rebrowse to the HeavyWeather file location. There is more information here:
    http://ambientweather.wikispaces.com/HeavyWeather+Default+File+Locations
  97. Version 14.01p11. Fixed issues with daily, monthly and yearly rain. Prevented 0.00 total rain value having effect on calculating the daily, monthly and yearly rainfall (some weather stations do not calculate these values so VWS must calculate them. However, some stations have issues with zero “spiking” to zero and causing the daily, monthly and yearly rainfall to reset to the total rainfall. VWS now throws out any zero rain value. I used to debouce it 5 cycles but that did not always work. Also changed the Settings | Rainfall panel to make it easier to edit daily, monthly and yearly values.
  98. Version 14.01p13. Updated database from 20,000 points to 50,000 points.
  99. Version 14.01p14. There was a bug in Version p13 that would give you an error message that the database was exceeded.
  100. Version 14.01p15. A couple of users are experiencing high and low summary read and write errors. I added code that creates a file called \vws\data\summary.txt to see what types of errors these are. You can send this file to me: ed@ambientweather.com if you have issues. Also, the summary files were only written once per day and at shutdown, and if you did not gracefully shut VWS down, you would lose this data. I now write this data once per minute.
  101. Version 14.01p17. Did not properly handle the day change highs and lows in Version 14.01p16. Fixed. Some users have complained of ghosting issues when program is unminimized. Fixed by maximizing, minimizing and maximizing again. Yikes, Windows can be flaky.
  102. Version 14.01p18-p19. Implemented new Davis DLL which fixes minor issues documented here: http://davisnet.com/support/weather/software_dllsdk.asp
  103. Version 14.01p20. Issues with resizing database resolved. No longer get annoying popup at start up if database needs resizing.
  104. Version 14.01p21. Some users still complaining about missing downloads. I have never been able to reproduce but I changed the keep alive write command. It would only send it out if data was read first. Now it sends it out regardless if any data was read back. I can not guarantee this will fix it, just trying different things out because I can not reproduce.
  105. Version 14.01p22. When the latest Davis DLL was implemented, it would default the display console to imperial units. I fixed this by getting the units first and then setting the same units in the get units command.
  106. Version 14.01p23. Found and fixed issue with plotting THWS parameters.
  107. Version 14.01p24-25. Added error tracing for daysum.txt file from the summary.txt file. One user is having issues with this file. Added Keep Alive Flag option for the WMR200. One user is having issues with no or interrupted downloads. I added this feature to troubleshoot. If downloads are intermittent, turn on or off this flag. Select Communication | Sensor Communication | Keep Alive Flag to set this flag.
  108. Version 14.01p26. Fixed issue with program crashing if more than 91 file parameters are selected for file reporting.
  109. Version 14.01p27. Fixed issue with database. Could not edit beyond 30,000 records.
  110. Version 14.01p28. If a warning is set and clears, the message “No Warnings” on the webpage will not be displayed.
  111. Version 14.01p30. Added WMR88A to list of weather stations. This is a new Oregon Scientific weather station. Also fixed crashing and display issues with Distribution Graphs for higher numbered parameters.
  112. Version 14.01p31. Version p30 broke Wind Direction distribution. Fixed.
  113. Version 14.01p32. Addressed issues with daily, monthly and yearly highs and lows that feed the displays and NOAA reports. The data would get corrupted. The new version will only allow a high and low to be entered if the current date and time exceeds the high and low date and time. This has something to do with the timing of the program with relation to the timing of the weather station clock, as well as bogus data. This can also effect the daily, monthly and yearly rainfall. Fixed issue with 5 day forecast. You must set up this panel again. Also fixed Davis Instruments forecast issue – if it is below 32 degF, the icon will show snow instead of rain.
  114. Version 14.01p33. Fixed issues introduced in p32.
  115. Version 14.01p34. Fixed issue related to highs and lows, Rainwise and introduction of p32.
  116. Version 14.01p36. Continue to troubleshoot Rainwise and highs and lows.
  117. Version 14.01p37. Fixed METAR reporting when temperature is missing from report.
  118. Version 14.01p40. Ongoing issues with Rainwise. Trying to resolve issues with highs and lows rolling over.
  119. Version 14.01p42. Resolved database overflow issue. The database would get corrupted if 50,000 points was reached and resized.
  120. Version 14.01p43. p42 did not completely resolve the issue.
  121. Version 14.01p44. Fixed crashing issue with WeatherBug.
  122. Version 14.01p46. Removed debug code for Peet Bros.
  123. Version 14.01p47. When Wunderground.com weather warnings time out, it does not parse the data properly. I did a few things: (1) increased the timeout from 10 seconds to 60 seconds (2) If there is a download error, the tag will display an error in retrieving data instead of No Warning. (3) under some circumstances, the tag would not parse properly.
  124. Version 15.00p00. Removed wininet.dll file. It was causing errors with Windows 8.1. Instead, it will get the dll from the system folder installed with the operating system.
  125. Version 15.00p03. Added WeatherBug support for Monthly and Yearly Rain.
  126. Version 15.00p04. Fixed crashing when WeatherCentral feature used.
  127. Version 15.00p05. Fixed more crashing issues.

The dew point is the temperature at which a given parcel of humid air must be cooled, at constant barometric pressure, for water vapor to condense into water. The condensed water is called dew. The dew point is a saturation temperature.

The dew point is associated with relative humidity. A high relative humidity indicates that the dew point is closer to the current air temperature. Relative humidity of 100% indicates the dew point is equal to the current temperature and the air is maximally saturated with water. When the dew point remains constant and temperature increases, relative humidity will decrease.

The standard calculation for Dew Point is here:

https://en.wikipedia.org/wiki/Dew_point#Calculating_the_dew_point

A well-known approximation used to calculate the dew point, Tdp, given just the actual (“dry bulb”) air temperature, T (in degrees Celsius) and relative humidity (in percent), RH, is the Magnus formula:

The more complete formulation and origin of this approximation involves the interrelated saturated water vapor pressure (in units of millibars, also called hectopascals) at TPs(T), and the actual vapor pressure (also in units of millibars), Pa(T), which can be either found with RH or approximated with the barometric pressure (in millibars), BPmb, and “wet-bulb” temperature, Tw is (unless declared otherwise, all temperatures are expressed in degrees Celsius):

For greater accuracy, Ps(T) (and therefore γ(T, RH)) can be enhanced, using part of the Bögel modification, also known as the Arden Buck equation, which adds a fourth constant d:

where
a = 6.1121 mb, b = 18.678, c = 257.14 °C, d = 234.5 °C.

  1. Copy the entire \vws directory from one computer (or drive) to another. To simplify the installation, copy all of the contents to the same pathname (for example, if VWS is installed on c:\vws on one computer, copy the directory to c:\vws on the other computer).
  2. Install Virtual Weather Station from your CD or Virtual Weather Station Download Center and install into the same directory as created on the new computer.
  3. If you install Virtual Weather Station into a different directory, there are several additional steps.
    1. Select Settings | Multiple Station Settings and select Recall Existing Station. Browse to the new directory location on the new computer. For example, if you install it into the c:\vws drive, browse to the c:\vws drive.
    2. There are several customized file paths you will need to change. Select the following windows from the menubar and change to valid directory locations.
    3. Settings | CSV Export
    4. Settings | Jpeg File Settings
    5. Settings | WeatherVoice
    6. Settings | WeatherCentral Settings
    7. Internet | HTML Settings
    8. Internet | Upload File
    9. Internet | Upload Folder

    If you copied the files from one computer to a CD and then to the other computer in Step (1), this sets all of the copied files to “read only”. To change this, on the new computer, right click on the \vws directory, select Properties and uncheck the read only check box.

    Note that you will not have to re-enter your registration number.

Temperature errors can occur when a sensor is placed too close to a heat source (such as a building structure, the ground or trees).

Bring the sensor inside a controlled environment where the temperature is stable, like your house or facility.

To calibrate temperature, we recommend a mercury or red spirit (fluid) thermometer.

Here is an example:

https://www.amazon.com/ACC610S-Precision-Laboratory-Thermometer-Immersion/dp/B00BQQFNCW

Bi-metal (dial) and other digital thermometers are not a good source and have their own margin of error. Using a local weather station in your area is also a poor source due to changes in location, timing (airport weather stations are only updated once per hour) and possible calibration errors (many official weather stations are not properly installed and calibrated).

Place the sensor next to the red spirit thermometer, and allow the sensor to stabilize for a few hours. Compare this temperature to the red spirit thermometer and adjust the console to match the fluid thermometer.

Why does Ambient Weather Ship UPS?

Ambient Weather selected UPS because of their shipping rates and service throughout the USA. We have signed an exclusive contract with UPS and these savings are passed on to our customers. The packages are tracked and insured electronically, which is a must for companies that ship large volumes of packages.

What are my shipping options?

Please visit: http://www.ambientweather.com/info.html

Why not ship USPS?

We do on occasion. It depends on the value of the item.

What about FedEx?

We had to choose one carrier to get the best shipping rates. FedEx does not cover 100% of USA and Canada.

What about Canada?

I am sorry, we do not ship to Canada. Too many customers complained about Canadian Customs, Brokerage and Import Fees. Often times, Amazon will ship to Canada and most of our products are available on Amazon.

Why not ship internationally?

Primarily fraud and returns. This drives up our costs for everyone. In addition to fraud, handling returns, customers refusing to pay unexpected import and duty fees, warranty issues, manufacturer exclusive distribution channels, and licensed wireless specifications are secondary reasons.

Often times, Amazon will ship to Canada and most of our products are available on Amazon.

Do we make any exceptions to shipping internationally?

I am afraid we do not.

Do we have international distributors?

I am afraid we do not.

What happens if my package is lost or stolen?

Please visit: Shipping Claims

I entered my address wrong. Now what?

If the package has shipped, you are subject to an intercept fee*
* UPS Delivery Intercept Fees:
$15.90 for web requests
$21.90 for phone requests
No charge for Will Call

How much does it cost to ship?

To determine shipping costs, add the Quantity to your shopping cart and select the >Buy Now button. The order page includes a shipping calculator. Enter your Zip or Postal Code and select Apply.

Note that you are not committed to a purchase by adding items to the shopping cart. This provides you with the total product cost + shipping. If the item is out of stock, you will not be able to add it to your shopping cart.

Wireless devices transmit a radio frequency (RF) signal, generally in the 400 – 900 MHz range. The manufacturer will rate the maximum transmission distance as line of sight. However, the signal will transmit through walls and other obstructions.

  • The following is a table of reception loss vs. the transmission medium. Each “wall” or obstruction decreases the transmission range by the factor shown below.
Medium RF Signal Strength Reduction
Glass (untreated) 5-15%
Plastics 10-15%
Wood 10-40%
Brick 10-40%
Concrete 40-80%
Metal 90-100%

 

  • RF will not transmit through metal barriers. If you have aluminum siding or a metal roof, it is unlikely the RF signal will transmit through this barrier.
  • RF will not transmit through earth. For example, if the receiver is placed in the basement, and the earth or ground is obstructing the line of sight transmission, it will not receive the signal.
  • Interference can be an issue. In general, wireless internet, phones, security systems and other low power devices have little interference effect. Ham Radio and other high power applications may lose data when transmitting.

Helpful Hint: Wireless phones transmit at similar frequencies and power levels as wireless weather devices. If you have a wireless phone (not a cell phone), place the receiver where you would place the weather station receiver and attempt to use the phone where you would place the transmitter. If you can not use the wireless phone, it is unlikely the weather station will work either.

Please reset your network in the proper order due to a DNS issue:

To Perform a Network Reset:

  1. Unplug power to modem, router and weather console/ObserverIP (unplug AC adapter and/or remove batteries).
  2. Plug power back into the cable Modem and let it sync back up with the network.
  3. Plug power back into the Router and let it sync up.
  4. Plug AC adapter back into the console/ObserverIP.

 

What is DNS?:

Domain Name Server or DNS is a server that translates websites’ addresses so that your browser can connect to them. If the addresses become out-of-date or the server has issues, you’ll encounter a DNS error and won’t be able to connect to a specific site or group of sites even with Internet access. You can potentially fix DNS issues by troubleshooting your current connection, flushing the DNS cache, disabling extra connections, changing your computer’s default DNS server, and even resetting your router

Problem

USB Port Locks Up, resulting in loss of software communication with the weather station console.

Discussion

This is a common complaint with all weather stations that operate using a USB port which is managed by the Windows Operating System for power management, unlike the more stable serial or TCPIP ports.

The following guide may alleviate but not completely solve your issue.

Solution

  1. Disconnect and reconnect the console from the USB port and confirm Windows recognizes the device. Restart the software.
  2. Try a different USB port on your computer and confirm Windows recognizes the device. Restart the software.
  3. Power down and restart the computer. Restart the software.
  4. Power down the console by removing from the USB port and removing batteries and AC power. Restart the software.
  5. If you are connecting through a USB hub as opposed to direct USB connection, connect directly to eliminate issues with the hub.
  6. Turn off all screen saver applications, which can interrupt USB data.
  7. Turn off all power save options. To view your options, select the Windows Control PanelPower Options and select Never for all of the power schemes. Select the Hibernate Tab and make sure the hibernate checkbox is unchecked.
  8. Turn off all USB power save features. Select the Windows Control PanelSystemHardwareDevice ManagerUniversal Serial Bus controllers, and select the plus (+) sign to view all of the USB controllers. You should see several USB Root Hub entries. Right click on each entry (unless you know which one is correct), select Properties, and under the Power Management tabuncheck the selection to Allow the computer to turn off this device to save power.
  9. If you are using a USB to serial converter, update your USB to serial communication drivers. Contact the USB to serial converter manufacturer and make sure you are running the latest drivers.
  10. If you are using a USB to serial converter, try a different USB to serial converter. Not all converters are created equal.
 

Also Consider

Virtual Weather Station is crashing.

If you are running Vista or greater, right click on the Virtual Weather Station icon on the desktop and select Run as Administrator to grant administrator privileges. This can cause certain features not to work. For all weather stations other than WeatherHawk, download the debug file here...

  1. If you are running Vista or greater, right click on the Virtual Weather Station icon on the desktop and select Run as Administrator to grant administrator privileges. This can cause certain features not to work.
  2. For all weather stations other than WeatherHawk, download the debug file here and install into the same directory as the previous installation:
    site.ambientweatherstore.com/vws/debug/vws_install.exe
  3. For WeatherHawk weather stations, download the debug file here and install into the same director as the previous installation:
    site.ambientweatherstore.com/vws/debug/whawk.exe
    This version includes debugging code that will provide Ambient Weather with the exact line and execution if the software is crashing within Virtual Weather Station.
  4. Re-run Virtual Weather Station and if the program crashes again, proceed to Step 5.
  5. If you receive the executable error and the ModName = cvi*.dll (any cvi module, for example, cvirte.dll), Virtual Weather Station is crashing then proceed to step (6). If the ModName is not cvi*.dll, if you have not done so already, please contact Ambient Weather by filling out the Problem Report Form. Please include the module name in the form.
  6. The debug version includes a full memory lap, requires more memory and runs slower then the normal version. When the program crashes, it will provide you with (1) the filename (usually formatted as main*.c, where * is the build number), (2) line number and (3) column number. Please email this information to support@ambientweather.com.
  7. if the ModName is wininet.dll, and you are running Internet Explorer 8 or greater, download the following DLL here
    and place in the same directory as the vws directory where you are running the appliction (usually c:\vws).
  8. If the ModName is wininet.dll, reducing the update rate sometimes eliminates the issue. Select Wunderground | Sign Up and Settings, and increase the rapid fire timer from 1 second to 3 seconds or more.

Notes

  1. One customer identified crashing on Windows7 when pure networks platform service was installed. Removing it eliminated the crashes.

    It is a program to assist you in setting up your home network for things such as printer sharing. If you do not know where it came from, it is often bundled in with routers from dlink and other companies.

    If you are asking if you can/should remove it from your computer and startup then the answer would be yes if you have no plans to use it.

  2. DEP. Virtual Weather Station Crashes under Windows 2003, or Windows Server 2008, 2012 when internet functions are performed, like ftp or jpeg file creation.

    Add Virtual Weather Station to the list of exceptions to DEP (Data Execution Prevention).

    For the purposes of program compatibility, you can selectively disable DEP for VWS.EXE when DEP is set to the OptOut policy level. To do this, use the Data Execution Prevention tab in System Properties to selectively disable DEP for a program.

    For IT professionals, a new program compatibility fix that is named DisableNX is included with Windows XP SP2. The DisableNX compatibility fix disables Data Execution Prevention for the program that the fix is applied to.

    If you are logged on as an administrator, you can manually configure DEP to switch between the OptIn and OptOut policies by using the Data Execution Prevention tab in System Properties. The following procedure describes how to manually configure DEP on the computer:

    1. Click Start, click Run, type sysdm.cpl, and then click OK.
    2. On the Advanced tab, under Performance, click Settings.
    3. On the Data Execution Prevention tab, use one of the following procedures:
    • Click Turn on DEP for essential Windows programs and services only to select the OptIn policy.
    • Click Turn on DEP for all programs and services except those I select to select the OptOut policy, and then click Add to add the programs that you do not want to use the DEP feature.
    4. Click OK two times.

Once connected, enter the following IP address into any browser’s address bar to access the console’s web interface:

http://192.168.1.1

 

 

 

Note: Some browsers will treat 192.168.1.1 as a search, so make sure you include the header http://, or: http://192.168.1.1 not 192.168.1.1

 

 

 

3. Enter the following information:

Enter the following information into the web interface (Figure Below). This model does not display sunrise and sunset, and therefore, there is no need to enter longitude and latitude.

 

Notes:

•Make a note of your Mac address. You will need this to register at AmbientWeather.net.

Hidden SSIDs. If you have a hidden SSID, enter the SSID manually.

Once the setup is completed, the Wi-Fi console will disconnect from your computer or smart phone’s Wi-Fi connection, and search for the assigned router. If the connection is successful, the Wi-Fi console’s Wi-Fi icon  will remain on

The Feels Like temperature is a combination of Heat Index when it is hot outside, and Wind Chill when it is cold outside.


Feels Like Temperature as a function of Wind Chill and Heat Index

Wind Chill temperature is defined by the National Weather Service for temperatures at or below 40 °F and wind speeds above 5.0 mph.

Heat Index is not valid or calculated below 80 degF.

Thus, when the outdoor temperature is between 40 degF and 80 degF, the feels like temperature is the same as the outdoor temperature.

If the temperature is below 40 degF, the feels like temperature is the same as the outdoor temperature when the wind speed is less than 5 mph.

If Virtual Weather Station (VWS) locks up:

  1. If you are upgrading to a new operating system or new computer, make sure you are running the latest version of Virtual Weather Station:Virtual Weather Station Versions & Legacy
  2. If you are using a USB to Serial converter, make sure your drivers are up to date on the converter.
    To troubleshoot the converter, unplug the USB cable from the computer. If it continues to lock up, it is program related. If VWS no longer locks up, the issue is with the USB drivers are USB to Serial Converter drivers.
  3. Select Communication | Communication from the menu and check the communication rate. If it is too fast, it may lock up the communications.
  4. If you are saving files over your local area network, turn this feature off in Virtual Weather Station. This can also occur when operating in “Stationless Mode”.

  1. This usually occurs when Virtual Weather Station is transferred from a computer to a CD to a different computer, overprotective virus protection software or setting a directory to read only status.
    Copying files to a CD will result in all of the directories to be changed to read only. Likewise, virus protection software can assign read only status to directories.
  2. If you are running Windows Vista, and change the installation path to the programs directory, Vista now locks any application from writing to this directory. Make sure you install Virtual Weather Station in the root directory (example, c:\vws).
  3. Security settings in Windows Vista, Windows 7 and Windows 10 may cause this.
  4. To change the read only status of Virtual Weather Station and associated sub folders, find the \vws directory in Windows Explorer and right click on the folder icon and select Properties. Uncheck the Read Only checkbox and select Apply. Apply changes to this folder, sub folders and files. If this does not work, you likely have virus protection software that has locked out changes to this directory and will need to add Virtual Weather Station to the approved programs list.
  5. Check your windows security settings. Make sure your Windows security is not set to High.
  6. If running Windows Vista, reinstall the software to the default directory, which is c:\vws.
  7. Select Settings | Multiple Station Settings from the Virtual Weather Station menu bar and browse to your local directory (the installed vws directory).

Sensors placed is shade on the north side of the house will experience lower daily highs and higher daily lows because of the radiant heat (and cooling) of the walls and structure around it. This is known as thermal mass, and has a time averaging affect (just like the temperature of your pool will respond faster than a lake).

Therefore, your sensor array with the low thermal mass and out in the open is much more accurate.

Description: Wireless weather stations provide simple installations and flexibility- you can move the console to a convenient location and do not have to run wires through the building. However, there are a few issues to consider:

  • Wireless Range: All wireless transmission ranges are specified “line of sight”, unless otherwise stated. Standard construction walls can reduce the transmission distance by as much as 50%.
  • Metal Enclosures: Metal enclosures (trailers), aluminum siding, reflective insulation materials, water (rain), reflective window treatments, and radio interference can greatly degrade the wireless transmission signal.
  • Transmitting through Earth and Ground: Never install your wireless weather station at an elevation below the console (such as down a hill), unless there is line of sight between the weather station and the console. The weather station will not transmit through ground or earth.
  • Repeaters: Some weather stations have optional repeaters that can be placed at a mid-point, allowing line of sight to both the weather station and the console.
  • Range: Weather station wireless range varies from 100′ to several miles, depending on the weather station type, frequency and repeaters.
  • Measurements: anemometerwind vanethermometerhygrometerbarometerrain gaugesolar radiation, which calculates evapotranspiration, and ultraviolet (UV) index.
  • Applications: Amateur weather watching, education, home automation, home environmental monitoring, landscaping.

barometer is an instrument used to measure atmospheric pressure.

To compare pressure conditions from one location to another, meteorologists correct pressure to sea-level conditions. Because the air pressure decreases as you rise in altitude, the sea-level corrected pressure (the pressure your location would be at if located at sea-level) is generally higher than your measured pressure.

It can also be used as a tool to predict weather.

If the Virtual Weather Station graphs stopped updating, it is likely due to a corrupt time and date in the database.

It may be a result of your weather station clock getting reset due to a power outage or a bad date written to your database. The weather station clock is reset if you lose power and you do not have back-up batteries in the console. If the console reads Jan 1 1999 (for example) and you are plotting the last 5 days, you will see no data in the graphs. The best way to make sure your date and time is view the broadcast display in Virtual Weather Station. This will reflect the console date and time.

  1. If you have a logging station (Davis Instruments, Rainwise, La Crosse, WeatherHawk, Texas Weather Instruments), check the date on your console. If the date is incorrect, correct the time and the graphs will start updating. Make sure you have back-up batteries in the console to prevent this form occurring again.
  2. If the date is correct, check your database to make sure a bad date has not been written to the database. Select Settings | Database Settings, reference the Total No. Records field. Next, enter this number in the Recall Record No. field and make sure the year, month and day are not corrupt (this can occur if there is a corrupt record in the console archive memory). Delete this record if it is corrupt and view the next record. Keep deleting record until the last date and time is less then or equal to the current date an time.

3. To completely delete the database, close Virtual Weather Station, then locate and delete the file \VWS\data\dbase.csv

To clean battery contacts or terminals:

  1. Put on your gloves. Alkaline battery corrosion can burn your skin, so it is important to keep your hands covered.
  2. Remove the battery and discard.
  3. Wipe away any large pieces of the corrosion with your wash cloth.
  4. Pour a small amount of white vinegar into a bowl.
  5. Dip a cotton swab into the vinegar and rub it along the corroded area. The vinegar will dissolve the corrosion. Repeat until the corrosion is gone.
  6. Dip your cotton swab into ordinary water and rub along the area that was corroded. This will help to remove any vinegar residue.
  7. Wipe the area down with a second wash cloth to make sure that everything is dry. The corrosion caused by the alkaline battery will now be gone.

Ambient Weather weather station and IFTTT working together

Using your Ambient Weather weather station and IFTTT the uses are endless.

The above video shows how easy it is to pair your Ambient Weather weather station with a Smart Life USB socket. When the weather station console reached 65° F then it communicated with the USB socket to turn on a floor fan. Imagine what it can do for you:

  • Automatically turn on fans/heaters for Orchards and other crops
  • Automatically turn on misters for livestock
  • Automatically turn off your Rachio sprinklers if it rains
  • Automatically turn on a floor fan when it reaches a certain temp
  • Automatically turn on that portable radiant heater to keep you warm
  • Close your Hunter blinds when the sun is too intense.
  • Close your garage door when it is too windy

Altimeters measure pressure, which is a function of altitude and barometric pressure. Normal fluctuations in barometric pressure will change the measured altitude at a fixed location.

A change is barometric pressure at standard sea-level pressure (29.92 in Hg) of 1 inch results in a change in measured altitude of 925 feet. To a lesser extent, barometric pressure (altitude) is also a function of temperature.

Thus, you must calibrate the altitude on a daily basis from a fixed location.

Make sure your module is plugged into AC power. It will not connect to Wi-Fi otherwise

 

When you first power up the module, or press and hold the WAP button for three seconds, the yellow WiFi LED will flash to signify that it has entered wireless access point (WAP) mode, and is ready to connect to the module’s WiFi.

You can use your desktop, laptop, tablet, or smart phone to connect to the module’s WiFi. The module’s network name begins with WeatherHome, followed by a unique code.

 

Once completed, you will return your device to the normal WiFi settings.

 

Example 1. Connect to the module Wi-Fi server with a PC. Choose Wi-Fi network settings from Windows (or search “Change Wi-Fi Settings” from Windows), and Connect to the WeatherHome, as shown in the Figure below (your Wi-Fi network name may be slightly different but will always begin with WeatherHome)

 

Example 2. Connect to the module Wi-Fi server with a Mac. Select the Settings icon and Network. Connect to the WeatherHome Wi-Fi network, as shown in the Figure below (your Wi-Fi network name may be slightly different but will always begin with WeatherHome).

Why does my PWS/Personal Weather Station not show up on the map?

The models WS-8482  will not show up on the map. The reason is  channel based sensors, unlike our weather station arrays, and the sensors can be placed inside or outside. We found lots of sensors not being placed outside, which polluted the map with bad data.

The Heat Index, sometimes referred to as the apparent temperature, is a measure of how hot it really feels when relative humidity is factored with the actual air temperature.

To find the Heat Index temperature, look at the Heat Index chart below. As an example, if the air temperature is 96°F and the relative humidity is 65%, the heat index (how hot it feels) is 121°F.

IMPORTANT: Since heat index values were devised for shady, light wind conditions, exposure to full sunshine can increase heat index values by up to 15°F. Also, strong winds, particularly with very hot, dry air, can be extremely hazardous.

The Heat Index Chart shaded zone above 105°F shows a level that may cause increasingly severe heat disorders with continued exposure or physical activity.

On June 21, 2018, the Supreme Court of the United States ruled in favor of the state in South Dakota v. Wayfair, Inc. The decision allows states to tax remote sales. What does it mean for out-of-state sellers? 

It used to be that states could only tax sales by businesses with a physical presence in the state. Now economic activity in a state — economic nexus — can trigger a sales tax collection obligation. Economic nexus is based entirely on sales revenue, transaction volume, or a combination of both.

How much bandwidth does my Weather Station Require?

The amount of uploaded data is dependent on the number of services you upload to, and sensors you own, but here is a rough guide:

For AmbientWeather.net upload every 12 seconds

Data stream: 174 Bytes

Total data in 24 hours: 86400/12 * 174 = 1252800 Bytes = 1.2MBytes (i.e.  36MB per month)

For WeatherUnderground.com: upload every 12 seconds

Data stream: 196 Bytes

Total data in 24 hours: 86400/12 * 196 = 1411200 Bytes = 1.34MBytes (i.e.  40MB per month)

The total is approximately 76MB per month.

Our weather stations base forecast on rate of change of pressure. This does not display what is happening right now, but rather, if the weather will change in the next 24 to 48 hours due to changes in barometric pressure.

In general, if the rate of change of pressure increases, the weather is improving (sunny). If the rate of change of pressure decreases, the weather is degrading (cloudy or rainy). If the rate of change is relatively steady, it will read partly cloudy or partly sunny (depending on the type of weather station).

The reason the current conditions do not match the forecast icon is because it is a prediction 24-48 hours in advance. In most locations, this prediction is only 70% accurate and it is a good idea to consult the National Weather Service for more accurate weather forecasts. In some locations, this prediction may be less or more accurate.

The National Weather Service (and other weather services such as Accuweather and The Weather Channel) have many tools at their disposal to predict weather conditions, including weather radar, weather models, and detailed mapping of ground conditions.  Thus, these forecasts are significantly more accurate then forecasts based on rate of change of pressure.

You will need to give the weather station enough time to predict changes in weather. This can take up to 30 days, depending on where you live.

FAQs:

California Prop 65:

WARNING: Use of the Ambient Weather Products can expose you to chemicals, including lead and lead compounds, which are known to the State of California to cause cancer and bisphenol A (BPA), andphthalates DINP and/or DEHP, which are known to the State of California to cause birth defects or other reproductive harm.

Can I Trust that Ambient Weather Products are Safe Despite this Warning?

In 1986, California voters approved the Safe Drinking Water and Toxic Enforcement Act known as Proposition 65 or Prop 65. The purpose of Proposition 65 is to ensure that people are informed about exposure to chemicals known by the State of California to cause cancer, birth defects and/or other reproductive harm.A company with ten or more employees that operates within the State of California (or sells products in California) must comply with the requirements of Proposition 65. To comply, businesses are: (1) prohibited from knowingly discharging listed chemicals into sources of drinking water;and (2) required to provide a “clear and reasonable” warning before knowingly and intentionally exposing anyone to a listed chemical. Proposition 65 mandates that the Governor of California maintain and publish a list of chemicals that are known to cause cancer, birth defects and/or other reproductive harm. The Prop 65 list, which must be updated annually, includes over 1,000 chemicals, including many that are commonly used in the electronics industry.

Although our manufacturing process is “lead-free” and RoHS compliant, it remains possible that trace amounts of lead could be found in components or sub assemblies of Ambient Weather Products. Bisphenol A (BPSA) could conceivably be present in minute amounts in our plastic housings, lenses, labels or adhesives, and DEHP & DINP (phthalates) could possibly be found in PVC wire coatings of our cables, housings, and power cords. Unlike RoHS, Prop 65 does not establish a specific threshold for reporting on the substances of concern and instead sets forth a much less definitive standard requiring that the business demonstrate with certainty that there is “no significant risk” resulting from exposure. With respect to carcinogens, the “no significant risk” level is defined as the level which is calculated to result in not more than one excess case of cancer in 100,000 individuals exposed over a 70-year lifetime. In other words, if you are exposed to the chemical in question at this level every day for 70 years, theoretically, it will increase your chances of getting cancer by no more than 1 case in 100,000 individuals so exposed. With respect to reproductive toxicants, the “no significant risk” level is defined as the level of exposure which, even if multiplied by 1,000, will not produce birth defects or other reproductive harm. In other words, the level of exposure is below the “no observable effect level,” divided by 1,000. (The “no observable effect level” is the highest dose level which has not been associated with observable reproductive harm in humans or test animals.) Proposition 65 does not clarify whether exposure is to be measured only in normal operation, or in the event of misuse such as intentionally damaging, incinerating or consuming an Ambient Weather Product or component and Ambient Weather has not attempted to evaluate the level of exposure.

A Proposition 65warning means one of two things: (1) the business has evaluated the exposure and has concluded that it exceeds the “no significant risk level”; or (2) the business has chosen to provide a warning simply based on its knowledge about the presence of a listed chemical without attempting to evaluate the exposure. The California government has itself clarified that “The fact that a product bears a Proposition 65 warning does not mean by itself that the product is unsafe.” The government has also explained, “You could think of Proposition 65 more as a ‘right to know’ law than a pure product safety law.”

While using Ambient Weather Products as intended, we believe any potential exposure would be negligible or well within the “no significant risk” range. However, to ensure compliance with California law and our customers’ right to know, we have elected to place the Proposition 65 warning signs on Ambient Weather Products.

Q: How do I measure snowfall?

 

A: Please refer to the link for the National Weather Service: https://www.weather.gov/jkl/snow_measurement

A: We built Ambient Weather and our associated products for our customers and not our competitor’s customers. Ecowitt is a competitor.

AmbientWeather.net is not free – it costs a lot to develop and maintain. It does not make good business sense to allow other companies to benefit from the website, when they had no part in developing it.

WeatherUnderground.com has a completely different business model where they sell your data and push advertising.

Since we don’t make money on selling ads, we only offset the cost of our servers and maintenance by selling hardware, and if you are buying other hardware than our own, the hosting service would not survive.

Ambient Weather stations are not designed to connect and send data over an open-air Internet connection such as cellular or satellite-based Internet. Even though the station may connect we cannot guarantee that it will send data consistently. This is due to a concept called Time to Live or TTL which states that our website is expecting data to arrive at a specific interval. The way data packets are handled by these type of connections does not allow the data to arrive when our website is expecting it. Therefore, the data is rejected as being invalid for not arriving at the correct time and you may see no data transmitting or inconsistent data transmission.
