MQ-4 Methane CNG Gas Sensor Module

This is a very easy to use low cost semiconductor Gas sensor Module with analog and digital output. This module uses 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 on-board potentiometer. Using this module you can easily interface MQ-4 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 sensitivity to alcohol & smoke.

Wiring Connection:

• VCC: positive power supply (5V)
• GND: power supply is negative
• DO: TTL switching signal output
• AO: analog signal output

Applications:

Suitable for home or factory methane gas , natural gas and other monitoring devices to test natural gas, methane 300 to 10000ppm

Features:

• Good sensitivity to Combustible gas in a wide range
• High sensitivity to CH4, Natural gas
• Small sensitivity to alcohol and smoke
• On brad potentiometer to set maximum gas concentration beyond which the digital output get triggered
• Fast response, stable, and long life
• Simple drive circuit
• Easy to interface with any controllers
