Fermion: MEMS Ammonia NH3 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.
