Air Sensors

Air can be measured in so many ways. Standard Air Quality such PM10 and PM2.5 is an index to evaluate the particle density in the air. Gas sensor is to measure the density of various gas such as Carbon Monoxide, CO2, Alcohol, CH4, CO/Combustible Gas and hydrogen. Anemometer is used to measure the air speed and direction.
