The DFRobot Fermion: MEMS Gas Sensor – MiCS-2714 (Breakout) is a compact and reliable sensor designed specifically for detecting nitrogen dioxide (NO₂) gas in the environment. Based on MEMS (Micro-Electro-Mechanical Systems) technology, the MiCS-2714 sensor offers high sensitivity, low power consumption, and a small footprint, making it ideal for applications in air quality monitoring, smart city infrastructure, portable environmental testers, and IoT-based safety systems. This sensor provides an analog output voltage corresponding to the concentration of NO₂ gas, which can be easily read using microcontrollers like Arduino, ESP32, or Raspberry Pi. Its fast response time and stability make it suitable for both real-time and long-term monitoring applications. The MiCS-2714 is built with a robust sensing layer that ensures reliability even in varying humidity and temperature conditions. It is particularly useful in detecting pollution levels caused by vehicle emissions or industrial processes. Housed on a breakout board with standard Gravity interface compatibility, this sensor simplifies wiring and integration, allowing for quick prototyping and development. Whether you’re creating an air quality station or integrating gas detection into a larger system, this sensor offers both accuracy and ease of use.
