Re: Connecting an Air Quality Sensor directly to an arduino

I have the Pro and therefore I am assuming that I need to use #define DHTTYPE DHT22, but I have tried the three values and none of them work. I am connecting the white pin to digital 10, is that a problem?

Thanks

Re: Connecting an Air Quality Sensor directly to an arduino

Thanks so much for your answer. I got the air working ok. I am trying to do the same with the Temperature and Humidity Pro just connecting the white to an analog input and red and black to red and black but I am not getting any signals, Do I need a yellow for the the Temp&Hum Sensor Pro?

Thank
