MP905 Air-Quality Gas Sensor

Profile

MP905 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

High sensitivity to benzene,toluene,formaldehyde,alcohol,smoke,lighter gas,paints;quick response and resume;

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

Main Application

It is used in occasions such as household and office for harmful gas detection, automatic exhaust device, air

cleaner&etc.
