MQ-2 Gas Sensor

MQ-2 Gas Sensor Module

The MQ-2 Gas Sensor Module is a versatile gas detection sensor designed to detect the presence of smoke and various combustible gases in the surrounding environment. It is commonly used with Arduino, Raspberry Pi, and other microcontroller platforms for gas monitoring, alarm systems, and DIY safety projects.

The module provides an easy-to-use interface with both analog and digital outputs, allowing users to monitor gas concentration changes or set a detection threshold using the onboard adjustment potentiometer.

Important Note

The MQ-2 is intended primarily for gas presence/detection and project-level monitoring, not as a certified safety or life-protection device. Sensor readings can be affected by temperature, humidity, sensor warm-up time, and environmental conditions. For critical gas-safety applications, use an appropriately certified gas detection system.
