DFRobot Fermion MEMS Formaldehyde Gas Sensor (0–3 ppm) - Analog Voltage Output
The DFRobot Fermion MEMS Formaldehyde (HCHO) Gas Sensor is a compact breakout module designed for qualitative detection of formaldehyde concentrations from 0 to 3 ppm. It operates on a 3.3V to 5V supply, providing an analog voltage output compatible with Arduino, Raspberry Pi, and other microcontroller platforms for air quality monitoring applications.
Features
- Advanced MEMS technology for compact size (13x13x2.5mm) and low power consumption (<20mA).
- Qualitative detection of formaldehyde (HCHO) gas within a 0-3 ppm range.
- Analog voltage signal output for easy integration with ADCs and microcontrollers.
- Wide operating temperature range from -10°C to 60°C.
- Extended operational lifespan of ≥3 years in typical air environments.

This Fermion series sensor utilizes micro-electromechanical system (MEMS) technology to achieve a miniature footprint, minimal heat generation, and rapid response and recovery times. It is engineered for qualitative assessment of formaldehyde gas concentration, making it suitable for integration into systems where trend monitoring is required rather than precise quantitative measurement.
The sensor requires a brief preheating period for stable operation and features a robust design for use in various environmental conditions, though it must be protected from corrosive gases, condensation, and mechanical shock. Its analog output provides a voltage signal proportional to gas concentration, simplifying interface with common data acquisition systems.
