Particulate matter is measured using two types of sensors. One is SODAQ AIR. It’s only slightly bigger than a bicycle bell so can be easily mounted on a bike to measure dynamic exposure to PM1, PM2.5, and PM10. It can also be used in a static mode from a fixed location.

Used in Sofia, Berlin.

The other one is a Sensor.Community kit which can be assembled from scratch or purchased as a ready-made station. The main sensing device uses laser light scattering principle to measure the value of dust particles (PM2.5, PM10) suspended in the air. 

Used in Athens, Berlin, Plovdiv, Sofia.
