Here we use an MQ2 gas sensor that detects the LPG, Alcohol, Smoke, etc, gases. If there is a gas in the air the resistance between two electrodes of the gas sensor gets increased according to the gas presence. We use node MCU as a microcontroller or a wifi development board that reads the analog values from the gas sensor. In the code, we set the gas value [200]. The node MCU sends these ...

The gas sensor needs about 5 volts of power in order to operate. This is done by connecting 5 volts to Vcc and GND. The Output pin gives out the voltage reading, which is proportional to the amount of smoke that the sensor is exposed to. Again, a high voltage output means the sensor is exposed to a lot of smoke. A low or 0 voltage output means the sensor is exposed to either little or no smoke ...
