MQ131 Ozone Gas Sensor Low Concentration Low Conductive In Clean Air

Sensitive material of MQ131 gas sensor is WO3, which with lower conductivity in clean air. When the ozone gas exists, the sensor’s conductivity gets lower along with the gas concentration rising. Users can convert the change of conductivity to correspond output
signal of gas concentration through a simple circuit. MQ131 ozone gas sensor has high sensitivity to ozone, and also has sensitivity to strong oxide such as Cl2, NO2 &etc. It responses oppositely to organic interference gases.

Features
It has good sensitivity to ozone in wide range, and has advantages such as long lifespan, low cost and simple drive circuit &etc.

Main Applications
It is widely used in domestic ozone concentration alarm, industrial ozone concentration alarm and portable ozone concentration detector.
