Arduino lesson – MQ2 Smoke Sensor –

Nov 16, 2018· Arduino MQ2 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.

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 aluminiumoxide based ceramic, coated with Tin dioxide, enclosed in a stainless steel mesh.
