Smoke Sensor (MQ2)
Quick Overview
This module uses MQ2 Smoke & Flammable gas sensor(LPG Gas) as a gas sensing element. It requires no external components just plug in Vcc & ground pins.For Digital output the threshold value can be easily set by an on-board potentiometer.Since this Gas Sensor module is sensitive to smoke it can be used in for fire detection. MQ2 Gas Sensor is also sensitive to flammable/combustible gasses like LPG, Propane & Hydrogen.

The MQ-2 Smoke LPG Butane Hydrogen Gas Sensor Detector Module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by the potentiometer.

MQ-2 gas sensor using gas sensitive material is to be clean air in the lower conductivity of Tin oxide (SnO2). When the sensor when flammable gases are present in the environment in which the conductivity of the sensor with an increasing concentration of combustible gas in the air increases.

Use a simple circuit to convert the changes in conductivity and output signal that corresponds to the concentration of the gas.

MQ-2 gas sensor higher sensitivity to liquefied petroleum gas, propane, hydrogen, detection of gas and other combustible vapors are ideal. This sensor can detect a variety of flammable gas, is a low-cost sensor for many applications.
