Fermion: MEMS Nitrogen Dioxide NO2 Gas Detection Sensor (Breakout, 0.1-10ppm) SF_GNSS Antennas It uses a small integratedFermion: MEMS Nitrogen Dioxide NO2 Gas Detection Sensor employs state of the art micro electromechanical system (MEMS) technology, endowing the sensor with compact dimensions (13x13x2. 5mm), low power consumption (20mA), minimal heat generation, short preheating time, and swift response recovery. The sensor can qualitatively measure the concentration of nitrogen dioxide gas, and is suitable for nitrogen dioxide detector, automobile exhaust detection,
