If anyone is interested i made a monitor station that measures a lot of indoor data, sends it via Wifi and logs it on a server.
Currently it's monitoring: Temperature, humidity, light, air pressure, sound level, co2 and tvoc level, dust level and PIR motion in the room.
The entire project is described here:
