• Description

MQ-2 Flammable Gas and Smoke Sensor + Interface Board

This semiconductor gas sensor detects the presence of combustible gas and smoke at concentrations from 300 to 10,000 ppm. The sensor’s simple analog voltage interface requires only one analog input pin from your microcontroller. 

Quick Spec

• Detects the presence of gas concentrations from 300 to 10 000 ppm
• Application: Domestic gas leakage detector
• High sensitivity to LPG, Propane, Hydrogen and Methane

Connections and Load Resistor

The board makes provision to mount the load resistor RL either horizontal or vertical. The resistance of RL should be calculated using the datasheet for your particular gas sensor.

Circuit Diagram

The MQ gas sensors have light to no polarity, so the gas sensor will work with the board all four ways it fits into the 6 pins (there are two possible orientations on each side of the board).
