1. Smart induction: When someone enters the detection range of this product, the microwave detector will turn on the light, and when the person leaves the detection range, the light will automatically go out. It can automatically recognize day and night 2. Intelligent delay: After detecting each human activity, the switch will automatically extend the cycle and start from the delay time of the last human activity 3. Working mode: After the sensor switch is turned on, if someone is active during the delay time, the switch will continue to be turned on until someone leaves and extends the time 4. Photosensitive control: According to the intensity of external light, control whether the switch is working to achieve energy saving effect 5. Compared with infrared products: the radar switch has a longer sensing distance, wide angle, no dead zone, can penetrate glass and thin wood, depending on the power, can penetrate walls of different thicknesses, regardless of environment, temperature, The influence of dust and so on. In the case of 37 degrees, the sensing distance will not be shortened. Radar switch is an ideal substitute for infrared switch
