Fermion: MEMS Hydrogen H2 Gas Detection Sensor

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.

• Compact size, measuring only 13*13*2.5mm
• Low power consumption, operating current ＜20mA
• High sensitivity and rapid response recovery
• Advanced MEMS technology

• Air quality monitoring: measures the level of H2 and other pollutants in the ambient air.
• Automotive emission control: monitors the H2 emission from fuel cell vehicles and adjusts the fuel cell operation to optimize the performance and efficiency.
• Industrial safety: detects the leakage or exposure of H2 and other flammable gases in industrial processes or workplaces.
