MQ-2 Gas Sensor Module Smoke and Flammable Gas Detector
VAT inclusive; Computed calculations added locally.
Overview
The MQ-2 Gas Sensor Module is a practical sensing solution for detecting smoke and flammable gases in electronics, robotics, automation, and educational projects. Its onboard sensing element responds to changes in gas concentration, while the integrated circuit provides a convenient output for connection to a microcontroller. An onboard adjustable potentiometer allows the detection threshold to be tuned according to the project's requirements and surrounding conditions. This makes the module useful for developing gas-alert systems, smoke detection prototypes, robotic safety projects, and environmental monitoring experiments. The module is designed for easy integration with popular development platforms such as Arduino and Raspberry Pi. Built-in mounting holes also make it convenient to attach the sensor to a project enclosure, robot chassis, or experimental setup.

Product Technical Information
Technical Details
The MQ-2 Gas Sensor Module is designed to detect smoke and a range of flammable gases for electronic sensing and monitoring applications. It is commonly used in Arduino, Raspberry Pi, robotics, and educational projects where changes in gas concentration need to be detected.
The onboard potentiometer allows the sensor threshold to be adjusted, helping users configure the module according to their project's environmental conditions. This can be useful when developing a simple gas or smoke alert system that needs to respond when the detected concentration reaches a selected threshold.
The module's compact design and M3 mounting holes make it easy to integrate into robot chassis, project enclosures, laboratory setups, and custom electronics assemblies.
Applications
- Smoke detection prototypes
- Flammable gas detection projects
- Arduino gas monitoring systems
- Raspberry Pi sensor projects
- Robotics safety and environmental sensing
- Home automation prototypes
- Educational electronics experiments
- Gas concentration monitoring projects
Package Includes:
1 × MQ-2 Gas Sensor Module
Note: MQ-series sensors require appropriate warm-up and calibration for meaningful measurements. Sensor response can vary with environmental conditions and the specific gas being detected. This development module should not be relied upon as a certified safety or life-protection device.
