MQ-4 Natural Gas Sensor Module
This is a straightforward MQ-4 Gas Sensor Module that detects the presence of Compressed Natural Gas (CNG), methane (CH4), and other gases in the air. Our MQ-4 sensor is used in the module. It simplifies the interface to the sensor's odd pin spacing by providing the interface via standard 4 x 0.1′′ header pins.It has an analogue output that corresponds to the concentration of gases in the air and a simple digital output. The onboard potentiometer can be used to set the maximum gas concentration that will trigger the digital output. The MQ-4 sensor is capable of detecting natural gas concentrations ranging from 200 to 10000ppm.
Simply connect the MQ 4 sensor module to 5V, set the threshold, and you can begin measuring the gas concentration in the air around the sensor! The presence of any gas is indicated by an onboard LED. Microcontrollers and other circuits can easily interface with the digital output. The analogue output can be connected to a microcontroller's ADC to obtain a wide range of sensor readings.
This is a simple compressed natural gas (CNG) sensor for sensing natural gas concentrations in the air (mostly Methane [CH4]).
If you want to use this MQ-4 Gas Sensor Module with Arduino, for that you will need
Features:
- Signal output indicator
- Dual Signals output (analog output and TTL output)
- The TTL output signal is low level, allows to connect with SCM directly
- High sensitivity
- Long working life and stable performance
- Quick response and recovery.

1. What are gas sensors? How do they work?
- Gas sensors (also known as gas detectors) are electronic devices that detect and identify different types of gasses. They are commonly used to detect toxic or explosive gasses and measure gas concentration.
Gas sensors detect the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage. Based on this voltage value the type and concentration of the gas can be estimated.
2. How to use the MQ4 Gas Sensor?
- As soon as the module is powered, the power LED lights up. The MQ-4 works by sensing the methane concentration in the air. The analog pin of the sensor then generates an analog signal proportional to the amount of CH4 in the air. We can measure the analog output of a sensor with an ADC microcontroller. The microcontroller then converts the measured analog voltage into Methane concentration in the air. Based on this measurement, we can take proper actions such as alarm triggering, etc.
Similarly, the same goes for the digital output pin of the MQ4 methane sensor. When methane gas is detected, the digital pin goes HIGH and the Digital output inbuilt led glows up. This digital pin can also be used for different activities being commanded by a microcontroller.
