The MQ-5 Gas Sensor Module is a compact electronic board used to sense combustible gases such as LPG, natural gas and methane. It is a popular building block for hobby electronics, Arduino and microcontroller projects, smart-home gas-leak alarms, and IoT safety experiments. It suits students, makers, automation enthusiasts and anyone building a simple gas-detection setup.
Key features
- Based on the well-known MQ-5 sensing element for combustible gases.
- Module board format that is easy to wire into breadboards and prototypes.
- Commonly provides both analog and digital outputs for flexible reading.
- Works smoothly with Arduino, ESP and similar microcontroller platforms.
- Small footprint, lightweight and easy to mount in projects and enclosures.
Typical uses
- DIY gas-leak alarm and home-safety projects.
- Arduino and Raspberry Pi learning and prototyping.
- Smart-home and IoT monitoring experiments.
- Workshop, lab and educational electronics demos.
How to choose / tips
- Confirm the MQ-5 is the right sensor for the gas type you want to detect.
- Allow the sensor a short warm-up period before taking readings, as the datasheet advises.
- Use the digital output for simple threshold alarms and the analog output for graded readings.
- Pair it with a microcontroller and a clear power supply for stable results.
