MMM-DHT22 Humidity and Temperature Module
-
I have test it with two dht22. One was mine and one I received from @Bangee who was so kind to test it before sending it and it was working at his home, but when I tried it at my home it wasn’t working. So I have no Idea what can be the failure.

Hi ,
so I just figure it out, that the motiondetector by alexyak blocking the DHT22 script. If I disable this module my DHT 22 works perfect. Somebody knows what make this problem? -
that’s very strange!?!
Is this module working with a PIR Sensor or a Webcam?
Im using Paviro’s PIR Sensor to turn on an off my monitor. -
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(
-
No one an idea?
-
I am using a PIR sensor.
So i can’t reproduce it. -
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_vardirect 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 ?
