Dec 22, 2020· Using MQ2 Gas sensor. MQ-2 Gas sensor is capable of detecting gasses like Alcohol, LPG, Propane, Hydrogen, Carbon Mono Oxide and methane. The module comes with a Digital Pin which helps this sensor to work even without a microcontroller. This arrangement is useful when you are simply attempting to identify one specific gas.
The output voltage from the Gas sensor increases when the concentration of gas increases. Sensitivity can be adjusted by rotating the potentiometer. For detail information about the MQ-2 sensor, please refer the data-sheet provided in Resources section.
