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}

Hii. Please help me . I have a pulse sensor and ir thermometer modules . I want to integrate them in magicmirror interface like dht 11 and others. But i dont find their MMM-module . Have some body a solution?.
Thank you.

@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

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.
