    With picamera. I installed MM on my other pi (completely new installation) and i got the same problem after i installed the motion detector. So I disabled on my MM the motion detector and it works fine on both pi’s. It’s very strange ;o(

          Dear guys,

          Ive tried to run this skript,nevertheless it’s showing me ‘undefined’ when I am running it in MM-Mode.
          Ive already checked the Pin setup and it should be right. Furthermore Ive checked your advises in the posts above me.

          Do you have an idea how to fix this error or even how to get an idea where the error is? :D

          Kind regards :)

            can you post a pic of your wiring?

            when you run the command sudo ./dht_var direct in your console, what happens?

              hy
              i have also the problem that the sensor shows only undefined.
              if i run your dht_var it shows nothing…
              sudo ./dht_var 2 5 returns after 5 seconds without any message…

              found out that it is only not working if i have enabled the PIR-Sensor Modul…

                @MxBln I have the same question. It works, but it shows me way to high temperatures and humidity. How did you do it with a DTC11 ?

                  same here, shows loading for a very long time and ‘undefined’ afterwards

                  the sensor is working, see here:

                    Are there any news for this module? I have the exact same thing with this module and the DHT22. Sometimes it shows everything correct and then it shows either “undefined”, nothing or ~ “-3200°C”. So it changes almost everytime it refreshes.
                    I also use the PIR module like Bangee but it doesnt matter if i have this modules activeted or not …the problem still is there.

                    sudo ./dht_var 22 5
                    

                    doesn’t do anything. It just returns with no massage like it does by schmo90.
                    Hope somebody can help us :)

                      Hi. I have the same issue, no response in the module or in the command line…

                      I am also using a PIR sensor, maybe it’s related?
