1: Easy to use and install - Using testing methods: 1. Ensure the correct wiring and installation of the micro-liquid sensor and the load lamp; 2. The use of microwave sensors (with ceiling mounted method) 2: Fully automatic sensing: Automatically turn on the light when sensing a person, turn on the light when coming and turn off the light when walking, safely save electricity, and be unaffected by external influences such as sound and objects 3: Sensitive sensing, accurately identifying the movement of living and non living organisms, minimizing the rate of misoperation. 4: Strong anti-interference: It adopts a working frequency of 5.8GHz and is less affected by external natural factors, with stable and reliable performance. 5: Automatic light metering: Automatically recognizes the intensity of ambient light, meets lighting requirements and lights up when there are people present. Otherwise, it will not light up. When someone enters the sensor and meets the lighting demand, the microwave switch will automatically turn on, the load appliance will start working, and the delay system will be activated. As long as the human body does not leave the sensing area, the load appliance will continue to work. When the human body leaves the sensing area,the sensor begins to calculate a delay.When the delay ends, the sensor switch automatically closes and the load appliance stops working.Truly achieved,safe,convenient, intelligent,and energy-saving.
