DFRobot Fermion MEMS Hydrogen Gas Sensor (0.1–1000 ppm) - Analog Voltage Output
The DFRobot Fermion MEMS Hydrogen Gas Sensor is a compact, low-power module designed for qualitative detection of hydrogen (H2) gas concentrations from 0.1 to 1000 ppm. It provides an analog voltage output compatible with 3.3V or 5V microcontrollers like Arduino, Raspberry Pi, and ESP32 for leak detection and safety monitoring applications.
Features
- Qualitative hydrogen (H2) detection from 0.1 to 1000 ppm concentration.
- Compact MEMS design measuring only 13 x 13 x 2.5 mm with low power consumption (<20 mA).
- Analog voltage output for easy integration with 3.3V/5V ADCs on Arduino, ESP32, or Raspberry Pi.
- Fast response and recovery time with a sensitivity ratio R0/Rs ≥ 5 in 200 ppm H2.
- Extended operational lifespan of ≥5 years in air with a wide operating temperature range of -10°C to 60°C.

This Fermion series sensor utilizes advanced Micro-Electro-Mechanical Systems (MEMS) technology to deliver a miniaturized hydrogen gas detection solution. The MEMS structure enables low heat generation and a short preheating time, contributing to rapid sensor response and stable performance. The module outputs an analog voltage signal proportional to the detected gas concentration, allowing for straightforward threshold-based alarm system design.
Designed for durability, the sensor operates across a humidity range of 15-90% RH (non-condensing) and is intended for qualitative monitoring applications. Proper handling is required to maintain sensor integrity, including avoidance of corrosive gases, silicon compounds, water exposure, and mechanical shock. A 24-hour preheat is recommended after extended periods of non-use to restore optimal performance.
