Fermion: MEMS Hydrogen Sulfide H2S Gas Detection Sensor utilizes advanced MEMS technology to enable a small footprint (13x13x2.5mm), low power draw (20mA), minimal heat production, rapid preheating, and rapid response recovery. This sensor can measure hydrogen sulfide levels accurately, and is suitable for H2S detection in bathrooms, sewers, garbage dumps, and other locations.
The MEMS series currently encompasses 11 different types of gas sensors (, , , , , , , , , , ), which can be combined as per specific requirements.
Please note: This sensor is capable of qualitative measurements only. For quantitative measurements, kindly consider purchasing the

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.
