MQ-2 Gas Sensor for Smoke Detection

This MQ-2 gas sensor is an electronic sensor that detects the concentration of gases in the air, including LPG, propane, methane, hydrogen, smoke, and carbon monoxide. It has a sensing material that changes resistance when it comes into contact with the gas. This change in resistance value is used for gas detection. MQ2 is a gas sensor made of metal oxide semiconductors. The sensor’s voltage divider network is used to measure gas concentrations in the gas. This sensor operates on a 5V DC power supply. It can detect gases with concentrations ranging from 200 to 10000ppm.
