Cảm biến khí H2 DFRobot Fermion: MEMS Hydrogen H2 Gas Detection Sensor (Breakout, 0.1-1000ppm) được sử dụng để đo nồng độ khí Hydrogen H2 có trong không khí, cảm biến sử dụng công nghệ MEMS cho kích thước nhỏ gọn, thời gian khởi động và phản hồi nhanh, tiết kiệm năng lượng vượt trội, cảm biến sử dụng giao tiếp Analog nên có thể dễ dàng đọc giá trị bằng ADC của Vi Điều Khiển.
Xin lưu ý:
Fermion: MEMS H2 sensor employs state-of-the-art micro-electromechanical system (MEMS) technology, endowing the sensor with compact dimensions (13x13x2.5mm), low power consumption (＜20mA), minimal heat generation, short preheating time, and swift response recovery. The sensor can measure the concentration of hydrogen gas qualitatively. It is suitable for the hydrogen leakage alarm and other application scenarios.
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.
