    MQ-2 Flammable Gas & Smoke Sensor
    • MQ-2 Flammable Gas & Smoke Sensor

    MQ-2 Flammable Gas & Smoke Sensor

    671

    Gas Sensor(MQ2) module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by the potentiometer.

    Description

    The MQ series of gas sensors use a small heater inside with an electrochemical sensor. They are sensitive to a range of gasses and are used indoors at room temperature. The output is an analog signal and can be read with an analog input of the Arduino.

    The MQ-2 Gas Sensor module is useful for gas leakage detecting in home and industry. It can detect LPG, i-butane, propane, methane, alcohol, hydrogen and smoke.

    Some modules have a built-in variable resistor to adjust the sensitivity of the sensor.

    Note: The sensor becomes very hot after a while, don't touch it!

     

    The connections are pretty easy:

    • Vcc to Arduino 5V pin
    • GNG to Arduino GND pin
    • Output to Arduino Analog A0 pin

     

    Note: The sensor becomes very hot after a while, don't touch it!
