MP901 Air-Quality Gas Sensor

Profile

MP901 gas sensor is for air quality. It adopts multilayer thick

film manufacturing technology. The heater and metal oxide

semiconductor material on the ceramic substrate of

encapsulated in metal socket and cap. Conductivity of the

sensor is affected by the concentration of target gas. The

higher the concentration is, the higher conductivity of sensor

gets. Users can adopt simple circuit to convert variation of

conductivity into output signal corresponding to gas

concentration.

Features

and resume; low power consumption, simple detection circuit, good stability and long life.
