The MQ-2 Gas Sensor Module is a versatile and widely used sensor designed to detect various combustible gases including LPG, methane, butane, hydrogen, and smoke. It is commonly used in gas leakage detection and safety systems.

This module features both analog and digital outputs, allowing users to monitor gas concentration levels and trigger alerts when gas levels exceed a predefined threshold. The onboard potentiometer enables adjustable sensitivity for accurate detection.

Compatible with Arduino, Raspberry Pi, and other microcontrollers, the MQ-2 sensor is easy to integrate into IoT and embedded systems. It is ideal for home safety systems, industrial monitoring, and environmental sensing applications.

⚠️ Note: Requires preheating time (~20–60 seconds) for accurate readings.
