product details

The MP801 air quality gas sensor adopts a multi-layer thick film manufacturing process, with heaters and metal oxide semiconductor gas sensing layers respectively made on both sides of a micro Al2O3 ceramic substrate, packaged in a metal shell. When there is a detected gas in the ambient air, the conductivity of the sensor changes. The higher the concentration of the gas, the higher the conductivity of the sensor. A simple circuit can be used to convert this change in conductivity into an output signal corresponding to the gas concentration.

Sensor characteristics

This product has high sensitivity to benzene, toluene, formaldehyde, alcohol, and smoke; It has the advantages of fast response and recovery, low power consumption, simple detection circuit, good stability, and long lifespan.

Main applications

Used for detecting harmful gases in home and office environments, automatic exhaust devices, air purifiers, etc.
