Design And Construction Of A Fire Alarm Using MQ2 Sensor

This fire alarm system composes of a MQ2 smoke sensor. This smoke sensor detects the concentrations of smoke in the air and outputs its reading as an analog voltage. The sensor can measure concentrations of flammable gas of 300 to 10,000 ppm. The sensor can operate at temperatures from 20 to 50°C and consumes less than 150 mA at 5 V.

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.
