Description
Overview
GAOTek wireless indoor air quality data logger is a compact indoor ambience monitoring sensor for measurement of temperature, humidity, light, CO 2 concentration, HCHO or O 3 level, TVOC, barometric pressure, PM 2.5, PM 10 and motion. The data will be shown on the E ink screen in real-time, which helps to measure the indoor environment and comfort. It is widely used for offices, stores, classrooms, hospitals, etc.
