MQ-4 High Sensitivity Gas Methane (CNG) Detector Sensor Module

MQ-4 High Sensitivity Gas Methane (CNG) Detector Sensor Module can sense the presence of Compressed Natural Gas(CNG), methane(CH4), etc in the air. The MQ-4 Sensor Module simplifies the interface to the odd pin spacing of the sensor and provides the interface through standard 4 x 0.1″ header pins.

This High Sensitivity Gas Methane (CNG) Detector Sensor is simple-to-use. 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. The MQ-4 can detect natural gas concentrations anywhere from 200 to 10000ppm.

Just power the module with 5V set the threshold and you can start getting the gas concentration of the air around the sensor! An onboard LED signals the presence of any gas. The analog output can be hooked up to an ADC of a microcontroller to get a wide range of sensor readings. This natural gas (CNG) sensor is suitable for sensing natural gas (composed of mostly Methane [CH4]) concentrations in the air.
