Multiple DHT22's over 3 channels and a RPi | Raspberry Pi | Forum

Hi guys

I have built a circuit with 5 DHT22s there data pins are connected to IO 21 20 16 26 12 respectively and power directly from the psu.

A total of 10 fields 2 each (Temp and humidity) with a max of 8 fields per channel I had to split the channels

unfortunately I have very little coding skills - using the below code I managed to get one sensor to work correctly.

I have no idea how to get it more readings to send, and also the fact that I need to send to more than one channel might be tricky..

Any help appreciated, thanks!
