Early in the summer I had placed a cm2302 temp/humid sensor outside to data log the readings. Well last night the -13.50 degrees temperature put my cm2302 into a frozen state. So, far the readings keep showing -13.50 while the temperature outside is actually +3 degrees. Now I am wondering if the sensor is fried, no, I mean frozen, and no longer functional. I am hoping it is just in hibernation until the temps get well above 32 degrees.
