Fermion: MEMS Volatile Organic Compounds VOC Gas Detection Sensor

Fermion: MEMS Volatile Organic Compounds VOC Gas 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 qualitatively measure VOC gas concentration and is suitable for indoor air quality detection, fresh air system, air purifier and other application scenarios. Kindly remove the protective film before usage. Gas detected: ethanol, formaldehyde, toluene, etc. Detection range: 1-500 ppm. It is advisable to preheat the module for at least 24 hours.
