Arduino lesson – MQ2 Smoke Sensor –

· The smoke sensor we will use is the MQ2. This is a sensor that is not only sensitive to smoke, but also to flammable gas. The MQ2 smoke sensor reports smoke by the voltage level that it outputs. The more smoke there is, the greater the voltage that it outputs. Conversely, the less smoke that it is exposed to, the less voltage it outputs.
