2pcs MQ131 Ozone Gas Sensor

[shortdesc]Application:It is widely used in domestic ozone concentration alarm, industrial ozone concentration alarm and portable ozone concentration detector.Feature:It has good sensitivity to ozone in wide range, and has advantages such as long lifespan, low cost and simple drive circuit &etc.[/shortdesc]Production Description:Sensitive material of MQ131 gas sensor is semiconductor metallic oxide, which with high 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 gases, such as Cl2, and NO2 etc. It responses oppositely to organic interference gases, compared with O3.Feature:It has good sensitivity to ozone in wide range, and has advantages such as long lifespan, low cost and simple drive ci
