AVAILABLE GAS SENSOR MODELS : MQ135 GAS SENSOR MODULEMQ2 Gas Sensor ModuleMQ3 Gas Sensor ModuleMQ4 Gas Sensor ModuleMQ5 Gas Sensor ModuleMQ6 Gas Sensor ModuleMQ7 Gas Sensor ModuleMQ7 Gas Sensor ModuleMQ8 GAS SENSOR MODULEMQ9 GAS SENSOR MODULE Sensitivity to Ammonia, Sulphide and Benzene steamSensitive for benzene, alcohol, smokeFast response and recoveryAdjustable sensitivitySignal output indicatorOutput voltage boosts along with the concentration of the measured gases increases. The MQ 135 Air Quality Detector Sensor Module For Arduino has lower conductivity in clean air. When the target combustible gas exists, the conductivity of the sensor is higher along with the gas concentration rising. Convert change of conductivity to the corresponding output signal of gas concentration. The MQ135 gas sensor has high sensitivity to Ammonia, Sulphide and Benzene steam, also sensitive to smoke and other harmful gases. It is with low cost and suitable for different applications such as harmful gases/smoke detection. Sensitivity to Ammonia, Sulphide and Benzene steamWith signal output instructionsThe TTL output signal is low levelAnalog 0 ~ 5 v voltage output, the higher the concentration, the higher the voltageColor is showing pictures.Sensitive for benzene, alcohol, smokeFast response and recoveryAdjustable sensitivitySignal output indicatorOutput voltage boosts along with the concentration of the measured gases increases.
