If you want to detect methane gases with your projects, you will need sensors. If you need any data on the sensitive material then, 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 which 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 and provides the interface through standard 4 x 0.1″ header pins.
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 digital output can be easily interfaced with microcontrollers and other circuits. The analog output can be hooked up to an ADC of a microcontroller to get a wide range of sensor readings. This is a simple-to-use compressed natural gas (CNG) sensor, suitable for sensing natural gas (composed of mostly Methane [CH4]) concentrations in the air.
