The MQ-4 High Sensitivity Gas Methane (CNG) Detector Gas Sensor Module is a quite good solution. This is a simple-to-use MQ-4 High Sensitivity Gas Methane (CNG) Detector Sensor Module that can sense the presence of Compressed Natural Gas (CNG), methane (CH4), etc in the air. The module uses our MQ-4 sensor. It simplifies the interface to the odd pin spacing of the sensor. It provides an analog output corresponding to the concentration of the gases in the air and an easy-to-use digital output. The onboard potentiometer can be used to set the maximum gas concentration beyond which the digital output gets triggered.

General Description:

The MQ-4 High Sensitivity Gas Methane (CNG) Detector Gas Sensor Module is a quite good solution. This is a simple-to-use MQ-4 High Sensitivity Gas Methane (CNG) Detector Sensor Module that can sense the presence of Compressed Natural Gas (CNG), methane (CH4), etc in the air. The module uses our MQ-4 sensor. It simplifies the interface to the odd pin spacing of the sensor. It provides an analog output corresponding to the concentration of the gases in the air and an easy-to-use digital output. The onboard potentiometer can be used to set the maximum gas concentration beyond which the digital output gets triggered.

Working Principle:

The MQ-4 gas sensor operates based on the conductivity changes of its tin dioxide sensing material when exposed to methane or natural gas. Integrated with a heating element, the sensor elevates the temperature of the material to facilitate chemical reactions with the target gas. In the presence of methane or natural gas, the interaction reduces the conductivity of the material, altering the electrical output of the sensor. This output, proportional to gas concentration, enables accurate detection for applications like gas leakage monitoring and safety systems.

Specifications:

1. Having an IC chip LM393 voltage comparator.

2. Operating Voltage (VDC) is 3V-5V.

3. It has the signal output indicating LED.

4. Having the dual signal output (analog and TTL output).

5. Long working life and stable performance by MQ-4.

6. It is highly sensitive to Gas Methane (CNG) detectors.

7. Operating Temperature: -10°C to 50°C.
