Product Description
Product Description
The DFRobot Fermion: MEMS Nitrogen Dioxide NO2 Gas Detection Sensor is a compact gas sensor module for qualitative detection of nitrogen dioxide in the 0.1 to 10ppm range. It uses MEMS technology and is intended for designs that require small size, low heat generation, short preheating time, and fast response and recovery behavior.
With dimensions of 13x13x2.5mm and current consumption below 20mA, the module fits space-constrained and low-power systems. According to the manufacturer, this sensor is intended for qualitative measurements only; for quantitative measurements, a factory-calibrated electrochemical sensor series should be used instead. Typical use cases include NO2 detectors, automobile exhaust detection, and integration into multi-sensor gas monitoring systems.
Technical Features
- Gas sensor module for nitrogen dioxide (NO2)
- MEMS sensing principle
- Qualitative detection range: 0.1-10ppm
- Compact size: 13x13x2.5mm
- Maximum current consumption: below 20mA
- Low heat generation
- Short preheating time with fast response and recovery

Application Areas
The module is suitable for qualitative nitrogen dioxide monitoring in embedded systems and prototypes. Typical applications include NO2 detectors, automobile exhaust detection, air quality monitoring, and combination with other gas sensors in multi-parameter measurement systems. Its small footprint supports integration into compact electronic assemblies.
Manufacturer handling notes should be observed during use. The protective film must be removed before operation. Exposure to volatile silicon compound vapors, high concentrations of corrosive gases, and contamination from alkalis, alkali metal salts, and halogens should be avoided. Long-term exposure to extreme environments should also be avoided.
