I'm using the NRG 200P wind vane for wind direction on the roof of a building.
Several days ago my sensor stopped working , so I opened it , and found a lot of rust inside , I cleaned it up , but still the sensor not working any more , it always gives me the same reading , 5V ,(I feed the power chords with stable 5V) , I can?t understand whats gone wrong?
I saw a capacitor inside, it was rusted and not functional, but I can?t believe it?s the reason, I think its purpose is to reduce noise.
Any ideas what gone wrong?
I added a photo of the open sensor
