I recently made built instructions [1] for a WiFi enabled CO2 monitor that can be used in schools and is a great project to built together with students. It shows the current CO2 levels with a large green, yellow red LED matrix. The kit comes with a custom PCB and 3D printable enclosure and is completely open source and open hardware. It uses the Senseair S8 NDIR sensor that we made really good experience with and can be programmed with the Arduino environment. More than happy to help any school (or anybody else) who wants to build these. [1] https://www.airgradient.com/resources/ https://www.airgradient.com/resources/
