The Fermion: MEMS Odor Smell Gas Detection Sensor (Breakout, 0.5-50ppm) is a cutting-edge sensor that employs microelectromechanical system (MEMS) technology. This compact sensor, with dimensions of 13 x 13 x 2.5 mm, is characterized by its low power consumption, minimal heat generation, brief preheating time, and rapid response recovery.

It is capable of qualitatively measuring the concentration of odor gas, making it an ideal choice for breath detectors, odor detection, and a variety of other applications. The sensor can detect a wide range of gases, including HCHO, CO, CH4, VOC, NH3, H2S, EtOH, Smoke, Odor, H2, NO2, although it is limited to qualitative measurements.

The sensor's design emphasizes compactness, low power consumption, and high sensitivity. It is versatile enough to be used in a range of applications, such as aviation safety, spoiled food material detection, body odor detection, and various health applications. The sensor operates at a voltage of 3-5 V and has an operating current of less than 20 mA. It has a detection range of 0.5-50 ppm and a lifespan of more than 5 years (in air).

Important Note: Prior to use, the protective film must be removed. Exposure to volatile silicon compounds vapors and high concentrations of corrosive gases should be avoided. It is also crucial to prevent contamination from alkalis, alkali metal salts, and halogens, and to avoid contact with water, condensation, and freezing. Excessive vibration, impact, and dropping should be minimized, and the module should be preheated for at least 24 hours after extended periods of non-usage.
