High Quality Craftsmanship: The motion sensor uses infrared sensor to detect human movement through fresnel lens in heat and polyolefin for high precision detection. High quality flame retardant material makes it safe to use. With a response time of 15 milliseconds, you can gain experience quickly and easily. Smart detection: The motion sensor detects human movements with passive infrared. It works with other smart accessories to set different scenes, such as: the automatic switching on or off of lights when activity or inactivity is detected. Motion sensor: built-in light sensor with body sensor to assess the brightness of interior light and provide more information for intelligent lighting. When the light is dark and someone comes by, the night light will turn on automatically. Create smarter ways: Create new ways to play with home products. Now all you have to do is place the human body sensor next to the TV, door or bed. You can intelligently detect movements of the human body or animal at any time and connect with other intelligent devices to make life intelligent everywhere. No tools to install: paste and use. The sticker on the base can also be placed in different places around the house. Multiple locations, suitable for different environments, no tools required for installation.
