Add up to 8 soil moisture sensors to your Ambient Weather WS-1965, WS-2000, WS-4000, and WS-5000 weather stations.

The soil moisture sensor measures moisture content in the soil, and transmits this information once per 72 seconds to the display console and our cloud service, AmbientWeather.net.

The information can then be accessed through the console, onliine dashboard, Amazon Alexa, Google Home, IFTTT, and much more.

The sensor features a ceramic cap, which acts like a breathing filter for exchanging soil moisture to the internal sensor. This filter makes the sensor less sensitive to soil density (clay, sand, soil, potting soil, etc.).

The console software also allows for 2-point calibration to assure accuracy.

The sensor can be placed inside or around your home, and you can send email, text or IFTTT alerts when watering is required.

The sensor has a wireless range of 300 feet (100 meters) line of sight (100 feet under most conditions).

The soil sensor includes a silicon (sand-like) medium cap, which reduces the sensor sensitivity to different soil types, since the silicon is a “known medium”.

A 48 to 72-hour time period is required for the sensor to completely dry out from a completely saturated state when transferred from water and air.

When placed in soil, the soil moisture sensor responds faster, because moisture is transferred freely in a similar medium (dirt, soil) through osmosis, as opposed to air or water.
