Mine DHT22 is working fine with SimpleDHT.h Library + UNO + IDE Example. Please, post your full codes with code tags so that we can see what library and what program you are using.

Hi,
Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.

Have you tried to load your UNO with the Blink example in the IDE to see if its is a hardware rather than a software fault?

Thanks.. Tom.. :slight_smile:
