How It Works:
The MQ2 Gas Sensor Module utilizes a tin dioxide (SnO2) semiconductor gas-sensitive material that exhibits a change in resistance when it comes into contact with the target gas. As the concentration of the gas increases, the sensor’s resistance decreases. This change in resistance is converted into analog or digital signals, indicating the presence and concentration of the detected gas.
Gas leaks pose serious risks, including fire, explosions, and health hazards. Installing the MQ2 Gas Sensor Module empowers you to monitor gas levels effectively, ensuring a safer environment for yourself, your family, or your employees.
