In order to measure air pollution dust sensors play an important role. They are often based on an optical system where light, scattered on dust particles is measured. I have 3 different sensors which should allow me to compare results:

Drivers and test software for the above dust sensors can be found at https://github.com/uraich/dust-sensors
