MQ-4 Methane (Natural Gas)  Sensor

The gas sensor used in the MQ-4 gas sensor is SnO2 with low conductivity in clean air.
– When there is a flammable gas in the environment where the sensor is located, the conductivity increases to increase the concentration of flammable gas in the air.
A simple circuit can be used to convert the change in conductivity to the output signal corresponding to the gas concentration.
The MQ-4 gas sensor is highly sensitive to butane, propane and methane, and has a good balance between methane and propane.
– This sensor detects a wide range of flammable gases, especially natural gas, and is a low-cost sensor for a variety of applications.
Suitable for equipment monitoring liquefied gas, natural gas and gas in the home or industry. Excellent resistance to ethanol and smoke.
