The Fermion MEMS Nitrogen Dioxide (NO₂) Gas Detection Sensor is a high-performance, low-power sensor designed using advanced microelectromechanical system (MEMS) technology. With its ultra-compact dimensions (13×13×2.5mm) and operating current under 20mA, it offers reliable and efficient detection of NO₂ gas in air. This qualitative sensor is ideal for automotive emission testing, air quality monitoring, and industrial safety systems where nitrogen dioxide exposure needs to be controlled. It delivers an analog voltage output for easy interfacing with microcontrollers like Arduino, ESP32, or Raspberry Pi. Designed for long-term stability, rapid response, and low heat generation, the Fermion NO₂ sensor provides an optimal balance between size, sensitivity, and efficiency for embedded or IoT-based applications.
