MQ-2 Gas Sensor for Smoke Detection MBR6045PT SCHOTTKY BARRIER DIODE 4mm Length 88mm Minimum PressureThis 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
