Finally done... 

Hello Zdeneck,

Looks like it will have the capability to attract the students attention at school, which I think is one of the purposes of this build.
It will be easy to explain the role of each sensor.

I would like to have the skills to write a little program in pyton (or any other suitable language) to use the IoT capability of the AQM II, where the students, on their computer could define a threshold for the CO2 or PM2.5 readings, and then get a warning message or even play a buzzer (Ideas for the IT class).

Thanks for sharing with us this different assembling for a different purpose.
