Motion Sensor has a built-in illuminance sensor. It detects the brightness of the room and provides more information for smart lighting. For example, if someone passes by and the indoor light is weak, it turns on the night light automatically. You can rotate 180 degrees of the Motion Sensor and adjust the detection angle with the sensor stand and sticker. Multiple placement options, suitable for different living environments. No tools required for installation. You can simply place it or paste it on a surface to use. High-quality craftsmanship. Motion Sensor adopts a Japanese infrared sensor to detect human motion through heat and a US Polyolefin Fresnel lens for high-precision detection. Made of anti-UV materials, the shell is color fadeless. With moisture-proof treatment, it works properly even in humid environments. The high-quality, fireproof material makes it safe to use. With a response time of 15 milliseconds, the switch will provide you with a rapid and convenient operation experience. With Mi Smart Devices, you can create magical scenes with your imagination. Before you go to bed, the air conditioner in the living room turns off; when you wake up at night, the night light lights up automatically. You can also link with other Mi smart devices to create more scenes. Simply place the Motion Sensor beside the TV, door, or bed, and it will trigger other smart devices according to your motion.
