Methane Gas Sensor (MQ-4)

Methane Gas Sensor (MQ-4)

MQ-4 Methane Gas Sensor is suitable for detecting the presence of methane (CNG) natural gas at a range of concentrations between 300ppm and 10,000ppm, making it ideal for gas leak detection. Like other MQ sensors, this sensor provides an analog voltage output based on the gas concentration. It is suitable for detecting gas leaks in the range of 10,000ppm to 300ppm.

By supplying 5V to the H pins, you ensure that the sensor heats up sufficiently, allowing it to operate with precise and accurate measurements. Applying 5V voltage to either A or B pin causes the sensor to provide analog voltage output through its other pins. You can adjust the sensor's sensitivity by changing the resistor value connected between the sensor's output pin and ground. The specific resistor value may vary depending on your application. As a starting point, you can use a 20 kΩ resistor.
