Ammonia Gas Sensor MQ137 sim800 Rated Current: 3–16AThe MQ 137 is an Ammonia (NH) gas sensor . Sensitive material of MQ137 gas sensor is SnO2, which with lower conductivity in clean air. When NH3 gas exists, the sensors conductivity gets higher along with the gas concentration rising. User can convert the change of conductivity to correspond output change voltage of gas concentration through a simple circuit. MQ137 gas sensor has high sensitivity to NH3 gas, also can monitor organic amine such as
