Hi
I have had the sensor working successfully on both the Duemillanove and a Raspberry Pi.
However using the same code on a 3.3v Arduino Pro Mini I simply get Zero's returned when using your DHT libraries.
Any ideas gratefully received.
Thanks
Steve

Re: DHT22 and Arduino Pro Mini
The DHT22's lower limit for power is 3.3v. Have you tried giving it a 4.5v - 5v supply?

Thanks Mike, I haven't tried that but I will. However it works fine at 3.3v when connected to a Raspberry Pi.
