Smoke Detection using MQ-2 Gas Sensor -

In this example, you will read the sensor analog output voltage and when the smoke reaches a certain level, it will make sound a buzzer and a red LED will turn on. When the output voltage is below that level, a green LED will be on. What is an MQ-2 Smoke Sensor? The MQ-2 smoke sensor is sensitive to smoke and to the following flammable gases: LPG

How MQ2 Gas Sensor works with Arduino. – MYTECTUTOR

The MQ2 gas sensor is a chemiresistor. That is, it contains a sensing material whose resistance changes when it comes in contact with a gas. This change in the value of resistance is used for the detection of gas. The sensing element is made of mainly aluminium-oxide based ceramic, coated with Tin dioxide, enclosed in a stainless steel mesh.
