Arduino lesson – MQ-2 Smoke Sensor «

· Arduino MQ-2 Smoke Alarm. The circuit we will build is shown below. So to power the smoke sensor, we connect pin 2 of the smoke sensor to the 5V terminal of the arduino and terminal 3 to the GND terminal of the arduino. This gives the smoke sensor the 5 volts it needs to be powered. The output of the sensor goes into analog pin A0 of the arduino.

Smoke Detector with Arduino & MQ2 Sensor - The Engineering ...

· Now let's place a burning cigarette near it for smoke. (Cigarettes are injurious to health :P ) When the sensor will sense smoke in its surroundings then its value will start to increase and in my case it reached to around 650. So, let's place a check in our Arduino coding to detect whether there's smoke or not. So add below code in your Arduino software and upload it to your Arduino board ...
