There has to be an easy method you are Thanks for the tutorial dude. You would just duplicate the code and use a separate pin to read the data for each sensor, Hi. Estimated annual energy consumption*: Approx. Here are the ranges and accuracy of the DHT11: The DHT11 measures relative humidity. hi guys.. i found the bug.. u need to pull up data/out/signal line with 10K to +ve line, Please do chk with multimeter.. u should get 10K between these two lines.. (S & +). The values could also change depending on the usage environment and conditions. The SHT31-D is more accurate and easier to install and costs about the same as the DHT11 /22 both of which really arent accurate at all.
