Ambient 1001 wifi Temp/Humidity Sensor Module!
« on: July 31, 2017, 12:09:02 PM »
Hi
My ambient weather 1001 wifi is 1.5 years old, I have a problem that my humidity and temperature sensors are giving false readings even after repeated calibrations. Also Temperature rises rapidly whenever heavy rainfall occurs against other PWS installed nearby (same thing happening with another 1001 wifi close to my location).
Talked to Ed a while back and his response was to buy new outdoor sensor. I am not from US and in my country PWS are not sold, hence its not possible for me to buy new sensor array as there is no possibility of going to US anytime soon plus shipment charges are way too high here.
I Just need to ask if there is any possibility that I could change the Humidity /Temp sensor by replacing with the new one. If its possible then if anyone could help in giving me exact sensor module number which is used by ambient  like e.g DHT22 Temp/humidity module.
Thanks!

HassanMohi, remove the radiation shield and if you see two sensors then:-
the temperature sensor is easy. It is a NTC 10K @ 25C bead thermistor. Make sure you get the 1% ones as a minimum.

As for the humidity sensor, I am not 100% sure, but according to my searches and spec sheets, it looks like it MIGHT be a HR202L.

Hope this help
