Arduino gas sensor MQ2, Smoke Detector, Programming & Circuit

· Gas Sensor MQ2 Interfacing with Arduino Uno: As you can see I have already connected 3 jumper wires, red is connected with VCC of the sensor module, black is connected with the Ground of the sensor module and white is connected with the analog output(A0) of the sensor Module. I selected A0 for the Smoke or Gas detection as this way I get more control over the MQ2 Gas/Smoke sensor. …
