MQ-2 Smoke Sensor Circuit Built with an Arduino

Arduino MQ-2 Smoke Sensor Circuit Schematic. 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. Through this connection, the ...
