· The MQ2 Gas sensor can detect or measure gasses like LPG, Smoke, Alcohol, Propane, Hydrogen, Carbon Monoxide (CO) and even Methane concentrations anywhere from 200 to 10000ppm. The module version of this sensor comes with a Digital Pin which makes this sensor to operate even without a microcontroller and that comes in handy when you are only trying to detect one particular gas…
· 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.
You should try experimenting with your MQ2 smoke gas sensor to set the threshold value. The LCD should print the Welcome message once the Arduino Nano is powered up. After 2 seconds, the LCD should display "Smoke Detector" in the first row and "MQ2" in the second row. The display should be cleared after 2 seconds. Use analogRead function to read the analog output of the MQ2 sensor …
