MQ-131 Ozone Gas Detector Sensor Module

MQ-131 Ozone Gas Detector Sensor ModuleThe sensitive material of the MQ131 gas sensor is O3 SnO2, which with lower conductivity in clean air. When Ozone gas exists. The sensor’s conductivity is higher along with the gas concentration rising. Please use a simple electro circuit, Convert the change of conductivity to correspond output signal of gas concentration. MQ131 gas sensor has a high sensitivity to Ozone, also sensitive to O3 CL2, NO2, etc.SpecificationsSensorMQ-131Detecting Range10PPB-2PPMWorking voltageDC 5VLength (mm)31Width (mm)22Height (mm)29Weight (gm)8Shipment Weight0.01 kgFeatures:Fast response characteristicsMounting holes to facilitate fixed installationThe probe can plug design for easy testing.Signal light indicates the outputDual signal output (analog output, and TTL-level output)TTL output valid signal is low; (low output signal light, can be accessed by the microcontroller IO port)Analog output increases with the concentration, the higher the voltage the higher the concentrationThe ozone gas with high sensitivity (detection concentration range 10PPB-2PPM Ozone)Long life and reliable stabilityPackage Includes:1 x MQ-131 Ozone Gas Detector Sensor Module
