MQ131 MQ-131 Ozone Sensor Module O3 Gas DetectorLow Concentration 10-1000ppb High Sensitivity for Portable Ozone Conce

Manual Click here to openOverview Sensitive material of MQ131 gas sensor is WO3 whichwith 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 Applications It is widely used in domestic ozone concentration alarm industrial ozone concentration alarm andportable ozone concentration detector Specifications Package Included 1 x MQ131 Ozone Sensor O3 Gas Detector ModuleModelMQ131product typeSemiconductor gas sensorStandard packagePlasticDetection of gasOzoneDetectable concentration10 1000ppb OzonStandard circuit conditionsCircuit voltageVc≤24V DCHeating voltageVH5 0V±0 1VACorDCLoad ResistanceRLAdjustableUnder standard test conditions sensing CharacteristicsHeating resistorsRH34Ω±3Ω Room temperature Heating consumptionPH≤900mWSensitivitySRs in air Rs in 200ppb O3 ≥2The output voltageVs≥1 0V in 200ppb O3 Concentration slopeα≤0 6 R500ppb R100ppbO3 Standard Test ConditionsTemperature humidity20°C±2°C 55 ±5 RHStandard test circuitVc 5 0V±0 1VVH 5 0V±0 1VWarm up timeLess than
