Fermion: MEMS Smoke Gas Detection Sensor
Fermion: MEMS Smoke Gas Detection Sensor employs state-of-the-art microelectromechanical system (MEMS) technology, endowing the sensor with compact dimensions, low power consumption, minimal heat generation, short preheating time, and swift response recovery. The sensor can measure smoke concentration qualitatively and is suitable for smoke alarm and other application scenarios. Kindly remove the protective film before usage. It is advisable to preheat the module for at least 24 hours. Detection range: 10-1000 ppm.
