  • The MQ-2 gas sensor is a type of sensor that detects flammable gas and cigarette smoke at concentrations of 300 to 10,000 ppm.

    The analog voltage information that it gives as an output according to the state of the gas in the environment makes it very easy to use the sensor.
    By supplying 5V to the H pins, you ensure that the sensor heats up sufficiently so that it operates precisely and with accurate measurements. Applying a voltage of 5V to pin A or B causes the sensor to output analog voltage over the other pins. You can change the sensitivity of the sensor in proportion to the resistance value you will connect between the ground and the output pin of the sensor. This resistance value may vary according to the application you will make, you can reach the calculations about it from the datasheet below. You can use a 20 kΩ resistor as an example starting value.
