Feature: 1. Sensitive sensing and accurate identification of the movement of biological and non‑biological bodies, to minimize the rate of misoperation. 2. Automatically identify the strength of the ambient light, and the light will be on when the lighting requirements are reached and there are people. 3. Using 5.8GHz working frequency, is not affected by natural factors outside, and the performance is stable and reliable. 4. Will automatically turn on the light after sensing a person, and the light will be off when the person goes out, which is safe and energy‑saving. 5. Strict quality control and quality assurance, high safety factor, can be used with peace of mind.
