I’ve burned through a few temp/hum sensors experimenting. Like when I get dew drift I’ve tried baking the sensor to recalibrate it. I wouldn’t do it. ;)
My leaf wetness sensor functions as a precip detecting sensor as I have it mounted on a metal electrical box with a 12 volt RV bulb inside to keep it warm and evaporate the precip as it falls. That’s shortened the life of those over the years. I’ve gone through a few anemometers as well. I have to get another one now as my speed stopped reporting. I can probably replace just the reed switch inside, but I’ll just get a new one and fix the old one later. Davis occasionally upgrades sensors so I’ll buy the new options as they come out. Mine’s been up since 2006 so that’s 15 years of some rough weather. I replaced a few cosmetic items a couple years ago too...like a few new rad shield plates, solar/uv mounts, and a new ISS transmitter (mine was cracking a bit).
