DFRobot Fermion MEMS CO Gas Sensor (5–5000 ppm) - Analog Voltage Output
The DFRobot Fermion MEMS CO Gas Sensor is a compact, low-power module for detecting carbon monoxide concentrations from 5 to 5000 ppm. It provides an analog voltage output compatible with 3.3V or 5V microcontrollers like Arduino, Raspberry Pi, and ESP32 for qualitative CO monitoring in safety and environmental applications.
Features
- Compact MEMS-based sensor measuring only 13 x 13 x 2.5 mm for space-constrained designs.
- Low power consumption with a maximum operating current of 20 mA, suitable for portable and battery-powered devices.
- Wide detecting range from 5 to 5000 ppm carbon monoxide (CO) for leak alarms and air quality monitoring.
- Analog voltage output signal for easy interfacing with ADC inputs on most development boards and microcontrollers.
- Extended operational lifespan of ≥5 years in air, providing long-term reliability for continuous monitoring systems.

This Fermion series sensor utilizes advanced Micro-Electro-Mechanical Systems (MEMS) technology to achieve its miniature footprint and efficient performance. The MEMS structure enables low heat generation and a short preheating time, allowing for rapid response and recovery to changes in carbon monoxide concentration. The sensor operates on a 3.3V to 5V DC supply and outputs an analog voltage proportional to the detected gas level, facilitating straightforward integration into data acquisition systems.
Designed for qualitative measurement, the module is ideal for applications requiring trend monitoring and threshold-based alarming rather than precise quantitative analysis. Its construction and specified sensitivity (R0/Rs ≥ 3 in 150ppm CO) make it suitable for environments where CO presence must be detected. The sensor is rated for operation within -10°C to 60°C and 15-90% RH non-condensing humidity, ensuring functionality in a range of indoor and controlled environments.
