MQ4 Gas Sensor Pinout Configuration

For MQ-4 Sensor Module

Pin Name	Description
VCC	This pin powers the module, typically the operating voltage is +5V
GND	Used to connect the module to system ground
Digital Out (DO)	You can also use this sensor to get digital output from this pin, by setting a threshold value using the potentiometer
Analog Out (AO)	This pin outputs 0-5V analog voltage based on the intensity of the gas

For MQ-4 Sensor

Pin No.	Pin Name	Description
1	H -Pins	Out of the two H pins, one pin is connected to supply and the other to ground
2	A-Pins	The A pins and B pins are interchangeable. These pins will be tied to Supply voltage.
3	B-Pins	A pins and B pins are interchangeable. One pin will act as output while the other will be pulled to ground.

MQ-4 Gas Sensor Features

Good sensitivity to Combustible gas in wide range
High sensitivity to CH4, Natural gas.
Small sensitivity to alcohol, smoke.
Fast response Stable and long life
Simple drive circuit
