DFRobot Fermion MEMS Methane Gas Sensor (1–10000 ppm) - Analog Voltage Output
The DFRobot Fermion MEMS Methane Gas Sensor is a compact, low-power module for qualitative detection of methane (CH4) and propane (C3H8) concentrations from 1 to 10,000 ppm. It outputs an analog voltage signal compatible with 3.3V or 5V microcontroller systems like Arduino, Raspberry Pi, and ESP32 for gas leak monitoring and safety applications.
Features
- Compact MEMS-based sensor measuring just 13 x 13 x 2.5 mm
- Low operating current <20 mA for energy-efficient embedded systems
- Analog voltage output for direct interface with ADC pins on microcontrollers
- Qualitative detection of methane (CH4) and propane (C3H8) gases
- Wide operating range from -10°C to 60°C and 15-90% RH

This Fermion series sensor utilizes advanced Micro-Electro-Mechanical Systems (MEMS) technology, enabling a miniature footprint, minimal heat generation, and rapid response/recovery times. It provides a qualitative measurement of combustible gas concentrations, making it suitable for leak detection and pre-alarm systems where relative changes in gas levels are critical.
The module requires a simple 3.3V to 5V DC supply and outputs a variable analog voltage corresponding to gas concentration. Its robust design supports a long operational lifespan of ≥5 years in air, provided usage precautions against corrosive gases, condensation, and physical shock are followed. It is intended for indicative monitoring and should not be used in life-safety critical systems without additional validation.
