Natural Gas Sensor MQ5 (Analog/Digital) 74HC164 GND: GroundProduct Description Sensitive material of MQ 5 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, The sensors conductivity is more higher along with the gas concentration rising. The sensor convert change of conductivity to correspond output signal of gas concentration. MQ 5 gas sensor has high sensitity to Methane, Propane and Butane, ch4 and natural gas . Features Support both the output digital
