First version of my sensor box.
It contains various sensors for Air Quality / Temperature / Humidity / Fine dust aquisiton.
I've never finished the software.
The air quality and alcohol sensor need 5V so you have to use a signal converter. In adition the NodeMCU has just one input so a ADC is neccessarily!
In the back it has an LED strip which is fixtured without screews.
