Hi Joan,

Sorry, I am new to python! I renamed the file per your instruction and the DHT22 sensor is working very well now. I changed the polling frequency to be much greater than 2s since for my application a slower refresh rate is perfectly fine. Thanks for your help!

Hi I have tried implementing Joan's python code at the beginning of this thread to read the DHT22 sensor but I get a python error: ImportError: No module named DHT22 which corresponds to line 178: import DHT22 It seems that python needs the DHT22 library. Does anyone know where to find it? Thanks John
