The Feinstaub-App is an application for monitoring of one or several sensors in a network of particulate matter sensors. Any number of sensors can be added or monitored. Comparing sensor data is possible too.
Info: For this app is a external particulate matter sensor required. The app isn't able to measure particulate matter with an Android device. We recommend a sensor from https://luftdaten.info/.
The app is OpenSource: https://github.com/mrgames13/Feinstaub-App
