Integrating LED sensor switches into smart homes is one of the hot topics in the current home intelligence. With the development of science and technology, smart homes are becoming more and more popular. The experience of “lights automatically turn on”, “turn on when you approach”, “turn on when you wave your hand”, “turn on when you open the cabinet”, and “lights turn off when you leave” is no longer a dream. With LED sensor switches, you can easily achieve lighting automation without complicated wiring or high budgets. It is worth mentioning that you can do all this by yourself!
