In this German publication we demonstrate how the phyphox BLE library for Arduino can be used to easily visualize data from a custom build sensor on your smartphone. We use CO2 sensor kits as an example, which have been designed as an assembly kit for schools during the pandemic. But besides being a tool to monitor air quality, the easy visualization with phyphox allows for more advanced uses in STEM classes, with experiments in Biology, Chemistry and of course Physics.
