DFRobot Gravity Analog LPG Gas Sensor MQ5 for Arduino - 5V Analog Output
The DFRobot Gravity MQ5 is an analog gas sensor module designed for detecting LPG, natural gas, and coal gas. Operating at 5V, it provides a simple analog voltage output compatible with Arduino, Raspberry Pi, and other microcontroller ADCs for gas concentration monitoring.
Features
- High sensitivity to LPG, natural gas, and town gas (CH4)
- Low cross-sensitivity to alcohol, smoke, and cooking fumes
- 5V DC power supply with simple analog voltage output interface
- On-board potentiometer for sensitivity adjustment and calibration
- Gravity-series connector for plug-and-play compatibility with DFRobot shields

The MQ5 sensor employs a metal oxide semiconductor (MOS) sensing element. When the target gases (LPG, natural gas) come into contact with the heated surface, the sensor’s conductivity changes proportionally to the gas concentration, which is output as an analog voltage signal. This signal can be read directly by a microcontroller’s ADC pin for gas level quantification.
Designed for stability and long-term use, the module includes a simple drive circuit and a potentiometer for calibrating the sensitivity threshold. Its construction is suitable for integration into gas leak detection equipment for both consumer and industrial safety applications, though it is optimized to minimize false triggers from common household vapors like alcohol and smoke.
