Hello,
My external DHT22 used to correctly display the humidity until now where the readings are very low (about 10% - whereas it should be much higher where I am). This is what Werk_AG mentioned in different threads: the DHT22 tends to go haywire in high humidity environments.
So I decided to replace it with a SHT21. I read the correct humidity level while the temperature is ... -312 degrees heheh.
Do you think is is due to the above problem? I use un-shielded cable, about 2m long.
Thanks!
