Sensor Analógico compacto MEMS de Compostos Orgânicos Voláteis VOC (Breakout, 1-500ppm) - DFRobot SEN0566

Fermion: MEMS Volatile Organic Compounds VOC Gas Sensor employs state-of-the-art microelectromechanical 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 qualitatively measure VOC gas concentration and is suitable for indoor air quality detection, fresh air system, air purifier and other application scenarios.

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.

Precautions for use

1. Kindly remove the protective film before usage.

2. 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).

3. Avoid exposure to high concentrations of corrosive gases (such as H2S, SOX, Cl2, HCl, etc.).

4. Prevent contamination from alkalis, alkali metal salts, and halogens.

5. Refrain from prolonged exposure to extreme environments (such as high temperatures, high humidity, high pollution).

6. Avoid contact with water, condensation, and freezing.

7. Minimize excessive vibration, impact, and dropping.

8. Please refrain from employing this module in systems that involve personal safety concerns.

9. For extended periods of non-usage, it is advisable to preheat the module for at least 24 hours.

1. Compact size, measuring only 13*13*2.5mm
