Ready !!! Dfrobot Mems Ammonia Nh3 Gas Detection Sensor 1-300Ppm

SKU: SEN0567 / KM3012 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). 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.
