I have a bunch of AM2302 sensors which I use for monitoring temp and humidity.
Now I have a few questions I have not found the answers to:
Powering off sensors between reads?
Are the sensors going to report OK values if they are powered off between readings? My reading interval is 60 minutes and I have found that some sensors will stop working after a while of being constantly powered.
If I just power cycle the sensors that have stopped working the values are again reported.
So I got an idea that maybe I should power them off between readings. Is this a bad idea? And if so why?
Time to stable readings
If a sensor is started up (see power cycle idea above) is there a recommended wait time until a reading can be taken at full accuracy?
If a sensor is just deployed to a new location, how long does it take for it to stabilize to the new temp/humidity?
I have noted that my sensors are labeled differently, older ones are marked:
and newer sensors are marked:
Are these from different makers or did AOSONG do a rebranding between my batches?
