Description

Winsen Electronics, research and produce air quality monitoring gas sensor for home and office air cleaners, and fresh air system.
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 subminiature Al2O3 are fetched out by electrode down-lead, 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:

High sensitivity to alcohol
smoke
formaldehyde
toluene
acetone
benzene
