Fermion's MEMS VOC Gas Sensor utilizes leading-edge MEMS technology, enabling it to be slim (13x13x2.5mm), efficient (20mA), operate without releasing heat, and react rapidly with a small preheating time. This sensor can assess VOC gas concentration objectively and is ideal for indoor air quality testing, ventilation systems, air purifiers, and other applications.
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 only qualitative measurements. 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.
