Ambient Weather WH31P Water Proof Probe Temperature Sensor
Note: TheWH31P sensor is not a stand-alone device and requires a WS-2902B (or greater revision), WS-1965, WS-2000, WS-4000, or WS-5000 weather station to view and upload the data to our cloud hosting service at AmbientWeather.net.
Accessory for the ObserverIP, WS-1965, WS-2000, WS-2902B, WS-2902C, WS-3000, WS-3000-X3, WS-3000-X5, WS-0265, WS-4000, and WS-5000 (total of 8 sensors).
The remote sensor includes a 10-foot waterproof probe, ideal for measuring any wet temperature medium, including water, soil, refrigerators, and freezers. This sensor has an IPX4 water resistance rating.
The probed sensor has a low thermal mass and responds quickly to temperature changes.
Notes:
- The WH31P can be used indoors and outdoors, but if used outdoors, it needs to be protected. Although the sensor is weatherproof, it is best to mount it in a well-protected area, such as an eve or in an enclosure like the Ambient Weather WH31-SRS Temperature and Humidity Solar Radiation Shield.

Q: Which sensors work with the WS-2902B console?
A: The WS-2902B will ONLY work with the WH31/WH31B/WH31E, WH31P (probed) and PM25/PM25IN sensors.
The sensors are “pass-through”, which means they will not appear on the local display console, but are displayed on AmbientWeather.net.
It will NOT work with WH31L (lightning), WH31LA (leak alert), WH31SM (soil moisture) .
