MQ4 Methane Gas Sensor rotary Max Temperature Difference (ΔT max):MQ 4 gas sensor sensitive material used in clean air conductivity is lower in tin titanium dioxide (SnO2). If the sensor is present in the environment in which the flammable gas, the sensor's conductivity increases with the concentration of flammable gases in the air increases. With a simple circuit, the change in conductivity of the gas concentration can be converted with the corresponding output signal. MQ 4 methane gas sensor for high sensitivity,
