Air quality sensor
The MP503 gas sensor is an air quality gas sensor. It is manufactured using a multilayer thick film process, with a heater and a metal oxide semiconductor gas-sensitive layer formed on both sides of a miniature Al2O3 ceramic substrate, led out by electrode wires, and packaged in a TO-5 metal housing. 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.
