MQ-131 Ozone Gas Detection Sensor module inductive ReSpeaker 2-Mics Pi HAT isMQ131 Sensitive material of MQ131 gas sensor is O3 SnO2, which with lower conductivity in clean air. When Ozone gas exists. The sensors conductivity is higher along with the gas concentration rising. Please use a simple electro circuit, Convert the change of conductivity to correspond to the output signal of gas concentration. MQ131 gas sensor has a high sensitivity to Ozone, also sensitive to O3 CL2, NO2, etc. FEATURES: Working voltage: DC 5V Size:
