DFRobot Fermion MEMS NO2 Gas Sensor (0.1–10 ppm) - Analog Voltage Output
The DFRobot Fermion MEMS NO2 Gas Sensor is a compact, low-power module designed for qualitative detection of nitrogen dioxide (NO2) concentrations from 0.1 to 10 ppm. It provides an analog voltage output compatible with 3.3V/5V microcontrollers like Arduino, Raspberry Pi, and ESP32 for air quality monitoring applications.
Features
- Advanced MEMS technology enables a compact 13x13x2.5mm footprint and low power consumption (<20mA).
- Qualitative detection of Nitrogen Dioxide (NO2) gas within a range of 0.1 to 10 ppm.
- Provides a simple analog voltage output signal for easy integration with 3.3V/5V ADCs.
- Features a rapid response and recovery time for dynamic gas concentration monitoring.
- Designed for a long operational lifespan of ≥5 years in typical air environments.

The Fermion MEMS NO2 Gas Sensor leverages micro-electromechanical system (MEMS) technology to deliver a highly miniaturized and efficient sensing solution. Its design minimizes heat generation and reduces preheating time, making it suitable for portable and battery-powered devices. The sensor’s metal-oxide semiconductor (MOS) sensing element reacts to the presence of NO2, producing a corresponding change in resistance output as an analog voltage.
Operating within a -10°C to 60°C temperature range and 15-90% RH (non-condensing) humidity, this sensor is built for indoor and controlled environment applications. It is intended for qualitative trend monitoring rather than precise quantitative measurement, ideal for detecting relative changes in NO2 levels commonly associated with vehicle exhaust, industrial processes, or general air quality assessment.
