MQ4-Methane CNG Gas Sensor

MQ4 Methane CNG Gas Sensor is a simple to use methane(CH4) and natural gas (CNG) sensor module. The module uses our MQ4 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.

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. The MQ4 can detect natural gas concentrations anywhere from 200 to 10000ppm.

Description

MQ4 Methane CNG Gas Sensor is a very easy-to-use low-cost semiconductor Gas sensor Module with analog and digital output. This module uses an MQ4 Methane gas sensor as a gas sensing element. It requires no external components just plug in Vcc & ground pins and you are ready to go. For Digital output, the threshold value can be easily set by an onboard potentiometer. Using this module you can easily interface MQ4 Methane (CNG) gas Sensor to any Microcontroller, Arduino, or even Raspberry Pi. Since this Gas Sensor module is sensitive to Methane it is also small sensitive to alcohol & smoke.
