CO2 Warngerät (CO2 warning device)

Summary

I have created a CO2 warning device with an Arduino Nano to monitor the CO2 concentration in rooms, offices, schools, and public institutions.
The appropriate housing is provided here.
There is also a video showing how the housing was created with AutoDesk Fusion 360.

Further details on the creation of the warning device can also be found at
