Monitor air pollution cheaply and accurately with this matchbox-sized particulate matter (PM) sensor from Plantower! It senses particulates of various sizes (PM1, PM2.5, PM10) from sources like smoke, dust, pollen, metal and organic particles, and more.
Pair this particulate matter sensor with our Enviro plus and build your own air quality monitoring station to contribute to citizen science. Just plug the cable into the sensor and then into the connector on the underside of Enviro plus, and away you go!
The sensor has a small fan that sucks air through the sensor and past a laser that can detect both the number (and hence concentration) and size of particles in the surrounding air.
