“Measure and display air quality with the Raspberry Pi.
This project is ideal if you already have a Raspberry Pi running 24/7, e.g., as web server, printer server, pi-hole etc. Then you can easily add extra functionality like air monitoring, which will be achieved by realizing this project. At the end, you will have a small status screen displaying temperature, humidity, TVOC and CO2 values.
To follow this guide, you need a Raspberry Pi. I used the Model 3, but any other model should work fine too. Install a Debian based Linux-Distribution like Raspberry Pi OS. Furthermore, you will need the remaining components as listed above. For the final build, I soldered everything together and installed it into a 3D printed case, but this isn’t absolutely necessary.”
