Winsen MQ-4 Methane Sensor is an original and brand new methane gas sensor. With a long lifespan and low price, for detecting Methane gas leakage. The sensitive material of the MQ-4 gas sensor is SnO2, which with lower conductivity in clean air. When the target flammable gas exists, the sensor’s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit. MQ-4 gas sensor has a high sensitivity to methane, also has anti-interference to alcohol and other gases. It is low cost and suitable for different applications of detecting kinds of methane concentration gases.
