Winsen air quality gas sensor from China
The MP901 air quality gas sensor uses a multi-layer thick film manufacturing process, with a heater and a metal oxide semiconductor gas-sensitive layer fabricated on the two sides of a miniature Al2O3 ceramic substrate, and is encapsulated in a metal shell. When the detected gas is present in the ambient air, the conductivity of the sensor changes; the higher the concentration of the gas, the higher the conductivity of the sensor.
