      Re: MMM-DHT22 Humidity and Temperature Module

      installed modules as described in read.me file but I get no reading of temp or hum.
      sensor is working, tested with AdaFruit example

      • sudo ./AdafruitDHT.py 2302 27 (Data connected to gpio 27)
        I get a perfect temp & hum reading, so i’m shure sensor is working.

      i’m using an RPI3 - according to wiring pin, wpi 2 = gpio27 = physical pin 13.
      I think wiring is OK.
      anybody can help solving this.
      thx

          Why aren’t you asking in the forum post for the module?

                nothing, all is perfect - no errors.

                yesterday tried every pin, nothing happens.
                Only module clock & this DHT22 module are in my config.
                Remover & reinstalled module.
                No luck .
                I thought sensor might be defect but I get a reading of temp & hum via the Adafruit DHT test program.
                I’ve seen other people have same problem - no reading. I’m wondering if they have sorted out or just gave up on this module.

                  @Johans No sure… I don’t have a sensor or I’d be happy to test it out …
