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..?
Yes but; Ideally your TX board will be adjacent to your radiation shield so no need to have a long cable. I expect you intend to use an SHT11 or better SHT15. The DHT22 will have a short life span outside particularly where humidity is high.
