Currently testing TX with DHT22 temp/hum sensor. Data sheet seems to indicate a digital output, and I'm reading of people using it up to 20 and 25m on a good cat5 or cat6 cable. So I guess 10 or 12m should be ok..??? And experiences out there..?
10 meters or even more will be ok for an DHT22 or for a SHT1x, but not for a SHT2x.
JT118 already said it on the post above, I'm just reaffirming it:
The DHT22 isn't suitable for long term use for outside readings. Go for an SHT1x or SHT2x depending the cable length you will need.
