Description: 1. Sensing Capabilities: The MQ-2 Gas Sensor Module can detect various gases, including Hydrogen (H2), Propane, LPG, Butane, Natural Gas, Methane (CH4), Smoke, and Carbon Monoxide (CO). 2. Operating Principle: This module utilizes the sensing principle of resistance to detect the presence and concentration of target gases. When a specific gas is detected, it alters the resistance level of the sensor element. 3. Integrated Heater: The integrated heater helps improve the sensitivity and accuracy of the MQ-2 Gas Sensor Module by raising the sensor temperature, which enhances the gas sensing properties. 4. Analog Output: The module provides an analog output voltage proportional to the concentration of the detected gas, making it easier for users to interface with microcontrollers or data acquisition systems. 5. Sensor Life and Calibration: The MQ-2 Gas Sensor Module has a typical lifespan of 1-3 years with regular use; however, sensor calibration may be necessary periodically to ensur
