Hi
I have started a project on GitHub for providing the software and hardware needed to build your own air quality monitoring station.
It allows to measure:
- the air quality with PMSA003 sensors,
- TVOC, temperature, relative humidity, pressure with BME688 sensor,
- CO2 with SCD41,
- the environmental noise level,
- the visible light and UV index, etc.
The processing unit is a Raspberry Pi5, the data read from the sensors is stored in a database and presented graphically by a local web server. The web server can be accessible over Internet by installing Tracescale VPN. The entire system can be easily adapted to specific needs and can be used indoors or outdoors.
