1Pcs MQ-131 Ozone NO2 Chlorine Gas Sensor - Semiconductor Detection 10-100PPM

Sensitivity: Rs(in air)/Rs(in 10ppm NO2)≥3. The change in conductivity can be converted into an output signal corresponding to the gas concentration using a simple circuit. The MQ-131 ozone sensor has high sensitivity to ozone and also has a certain sensitivity to strong oxidizing gases such as chlorine and nitrogen dioxide.
