Fermion: MEMS Ammonia NH3 Gas Detection Sensor (Breakout, 1-300ppm)

Description

Fermion: MEMS Ammonia NH3 Gas Detection Sensor utilizes cutting-edge micro-electromechanical system (MEMS) tech, offering a 13x13x2.5mm footprint, 20mA power draw, low heat output, swift heating and recovery time. It enables a qualitative measure of ammonia concentration, making it ideal for cold storage leakage detection, aquaculture hazard prevention, bathroom odor management, and other contexts.

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.

Please note: This sensor is capable of qualitative measurements only. For quantitative measurements, kindly consider purchasing the Gravity: NH3 Sensor (Calibrated).

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.
