A Low-cost Air Quality Sensor for Measuring Particulate Matter

WebParticulate matter is the general term used for a mixture of solid particles and liquid droplets in the air. It includes aerosols, smoke, fumes, dust, ash and pollen. The composition of particulate matter varies with place, season and weather conditions. Fine particulate matter is particulate matter that is 2.5 microns in diameter and less. WebLargely sized particulates can be grit (diameter of 500 μm ), fly ash and dust (diameter ranging between 0.25 - 500μm). Small sized particulates are fumes (less than 1 μm), mist (liquid droplets of diameter less than 2 μm) and aerosols (diameter of less than 1 μm). Hence, nitric oxide does not form a part of the particulate matter.
