      Hello everyone,
      Does someone already integrated sensor type MH-4R (Intelligent Infrared Gas Module) as a module into his/her MagicMirror?

      Datasheet:
      MH4-R

      It measure the air quality and give you the “parts per million” (unit ppm) back.

      Sensor is tested and working with the following:

      mkdir co2 cd co2 git clone https://github.com/IT-Berater/mh-z19.git cd mh-z19 ./setup.sh sudo python -m mh_z19 {‚co2‘: 668}

      @sranj ok, so u receive the trigger in the node_helper, and need to launch/exec/spawn your python pgm

      so you need the child_process library
      https://nodejs.org/en/knowledge/child-processes/how-to-spawn-a-child-process/

      PIR uses the same library to launch the tvservice command, or vgencmd to blank the screen

      @Justinvd0203
      I had a similar problem with my LG Monitor and PIR-Sensor.
      In my case i had the following behavior:

      Using HDMI Connection: switching off was possible, wake up not Using VGA Connection (with HDMI->VGA adapter on RPI side): switching off an wake up was possible

      Details see post.

      No worry using HDMI->VGA adapter: VGA can also deliver FullHD Resolution.

      Maybe your problem could be solved with an adapter.

      @elleclouds - If I understand you properly, then this is what you’re looking for: Motion Detection with RaspiCam Non-Module Version
