This gas sensor module uses an MQ4 high sensitive gas sensor as a sensing element. This is a simple device that senses the presence of Methane (CNG) gas at a concentration from 300 ppm to 10,000 ppm, a range suitable for detecting gas leakage. This device can detect CH4, natural gas, LNG, avoid exposure to alcohol, cooking fumes, and cigarette smoke. 

The module is quite simple to use and interface with any controller like Arduino, Raspberry Pi, AVR, etc. it provides an analog output corresponding to the concentration of the gases in the air and an easy-to-use digital output. The device requires minimal external components, just connect the VCC and GND and you are ready to go.
