The MQ2 Gas Sensor Module is a metal oxide semiconductor (MOS) sensor that is used to detect the presence of flammable gases and smoke. MQ2 Gas Sensor is a relatively inexpensive sensor that is easy to use and can be integrated into a variety of applications.

Smoke Sensor MQ2 works by measuring the change in resistance of a sensing element when it is exposed to different gases. The sensing element is made of tin dioxide, which is a semiconductor that changes its resistance when it comes into contact with different gases. When the sensor is exposed to a flammable gas, the resistance of the sensing element decreases. This change in resistance can  measure and use to determine the concentration of the gas in the air.

The MQ2 Gas sensor can detect a variety of flammable gases, including LPG, propane, methane, hydrogen, and alcohol. It can also detect smoke. The sensor has a sensitivity range of 200 to 10,000 parts per million (ppm), which means that it can detect very small concentrations of gas.

The MQ2 gas sensor has an input voltage of 5V. This means that it must be powered by a 5V source. The sensor also has a maximum output voltage of 5V. This means that the output voltage of the sensor will never exceed 5V.

Smoke Sensor MQ2 is a relatively simple sensor to use. It has four pins: VCC, GND, DOUT, and AOUT. VCC is the power supply pin, GND is the ground pin, DOUT is the digital output pin, and AOUT is the analog output pin.

Once the sensor is powered up, it will start to detect gases. The DOUT pin will go high when the sensor detects a gas. The AOUT pin will output a voltage that is proportional to the concentration of the gas.

Features : –

To power the MQ2 gas sensor, you will need to connect the VCC pin to a 5V source. The GND pin should connect to ground. The DOUT pin can connect to a digital input pin on your microcontroller. The AOUT pin can connect to an analog input pin on your microcontroller.

Here are some of the key features of the MQ2 gas sensor:

  • Can detect a variety of flammable gases and smoke
  • Has a sensitivity range of 200 to 10,000 ppm
  • Is relatively inexpensive and easy to use
  • Can integrate into a variety of applications
