MQ131 Semiconductor Sensor for Ozone


Sensitive material of MQ131 gas sensor is SnO2  which with lower conductivity in clean air. When Ozone gas exists. The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuitConvert change of conductivity to correspond output signal of gas concentration.

MQ131 gas sensor has high sensitity to Ozonealso sensitive to CL2NO2etc.


  • Good sensitivity to Ozone in wide range
