The MQ2 smoke sensor detects combustible gases, including smoke, LPG, propane, and methane. It operates using a metal-oxide semiconductor (MOS) gas sensing layer, which changes resistance in the presence of gas. The sensor provides both analog and digital outputs, making it compatible with microcontrollers. It is widely used in gas leak detection, fire alarms, and air quality monitoring systems. The MQ2 sensor operates at 5V and requires preheating for stable performance. It is highly sensitive to flammable gases and smoke, making it useful in industrial and household safety applications. The module is compact, reliable, and easy to integrate into IoT-based gas detection projects.
