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 ...

MQ 2 Gas Sensor - IoCT

Figure 2: Schematic of MQ-2 Gas Sensor from Datasheet. 2The MQ 2 sensor is a metal oxide semiconductor (MOS), also known as a chemiresistor. MOS sensors measure the change in resistance when gases are present. This type of sensor requires the gas to encounter the sensor for a chemical reaction to occur. This chemical reaction causes a change in resistance, which is then measured to …
