Description
Fermion: MEMS Smoke Gas Detection Sensor leverages modern microelectromechanical system (MEMS) technology, boasting compact 13x13x2.5mm dimensions, low power consumption (20mA), negligable heat production, fast preheat time, and fast response recovery. The sensor can accurately quantify smoke concentration and is ideal for smoke alarm and other use cases.
The MEMS series currently encompasses 11 different types of gas sensors (HCHO, CO, CH4, VOC, NH3, H2S, EtOH, Smoke, Odor, H2, NO2), which can be combined as per specific requirements.
Please note: This sensor is capable of only qualitative measurements. For quantitative measurements, kindly consider purchasing the Gravity: Factory Calibrated Electrochemical Gas Sensor Series.

Precautions for use
Kindly remove the protective film before usage.
To prevent exposure to volatile silicon compounds vapors (such as silicone adhesive, hair gel, silicone rubber, or other locations where volatile silicon compounds are present).
Avoid exposure to high concentrations of corrosive gases (such as H2S, SOX, Cl2, HCl, etc.).
Prevent contamination from alkalis, alkali metal salts, and halogens.
Refrain from prolonged exposure to extreme environments (such as high temperatures, high humidity, high pollution).
Avoid contact with water, condensation, and freezing.
Minimize excessive vibration, impact, and dropping.
Please refrain from employing this module in systems that involve personal safety concerns.
For extended periods of non-usage, it is advisable to preheat the module for at least 24 hours.
