temperature and humidity DHT22



  • I have the dht22 sensor hooked up and working on a pro mini on pin 3 I get a normal temp reading but the humidity always stays at 1.0 does not read.



  • Is it outdoor and humidity is high I have seen that before.
    Is it indoor then the sensor can be damage



  • one is outdoor it worked before I upgraded gateway to 2.1 the other is indoor both running the new 2.1



  • What sketch you use ? I cant get yesterday this working. GW is last 2.1, serial monitor printing fine and all is ok but i do not see this sensor in Domoticz
