MQ2 gas sensor is an electronic sensor used for sensing the concentration of gases in the air such as LPG, propane, methane, hydrogen, alcohol, smoke and carbon monoxide. MQ2 gas sensor is also known as chemiresistor. It contains a sensing material whose resistance changes when it comes in contact with the gas. This change in the value of resistance is used for the detection of gas. MQ2 Gas ...

The gas sensor MQ2 suitable for detecting of LPG, i-butane, propane, methane, alcohol, Hydrogen, smoke etc. Since It is highly sensitive and gives fast response, we can take measurements as soon as possible. This sensor can be used for gas leakage detection. fig 1: MQ-2 sensor schematic. At normal condition, sensor resistor will be high so voltage drop across the load will be low and it will ...
Smoke Gas LPG Butane Hydrogen Gas Sensor Detector Module MQ-2 MQ2 ... This pin outputs 0-5V analog voltage based on the intensity of the gas: For Sensor: 1: H -Pins: Out of the two H pins, one pin is connected to supply and the other to ground: 2: A-Pins: The A pins and B pins are interchangeable. These pins will be tied to the Supply voltage. 3: B-Pins: The A pins and B pins are ...
The analog signal from MQ2 Gas sensor is further fed to LM393 High Precision Comparator (soldered on the bottom of the module), of course to digitize the signal. Along with the comparator is a little potentiometer you can turn to adjust the sensitivity of the sensor. You can use it to adjust the concentration of gas at which the sensor detects it. The sensor is sensitive to multiple gasses ...
