This is so far my test bench. I plan to test it for the next couple of weeks and see how it reacts to various gases.
Any feedback or experience from fellows that are using already VOC sensors is highly appreciated!


The VOC sensor is the TGS8100 from Figaro
It is a promising little sensor with quite a low power consumption, which shouldn't affect all too much the temperature reading (so they say, but i need to test);

There is already a breakout board for this sensor from Unitronic,

Though it costs 60 euro, and my target is 30.
All in all it will be a small board that can be connected to the existing CO2/Dust monitors via a couple additional wires - so easy upgrade.
But since the sensor will be driven by an Atmega328, this leaves the possibility also for standalone operation, and - e.g. connecting some RGBLED Strip to have a standalone VOC meter.

Still need to check when exactly VOC levels change though

promising update!
