The easiest part of smart home is smart lighting. From Philips' Hue to Wemo's intelligent switch to Xiaomi's intelligent light bulb, each company has different technologies, but they can basically realize basic functions such as remote control and timing switch. Combined with Alexa/Siri, voice control can also be realized. At this point, home lighting is already more intelligent. This article mainly introduces how to further add the human body sensing function on this basis. Some brands of lights have human sensing functions. For example, Hue has motion sensing sensors that can be connected to Hue bulbs. Xiaomi also has an author: graphot

However, their disadvantage is that they only play the role of automatically turning on and off the lights, which is not very different from the common voice control lights. For example, when you go to the toilet, you have to defecate and clap/wave your hands to keep the light from exceeding the time limit.. At the same time, these sensors can not achieve more precise control of the light. For example, when I rushed into the toilet at night, the lights were all on at once, and my krypton gold dog's eyes would be blinded.. Therefore, this article mainly introduces my thinking and realization of humanization on how to do intelligent lighting.
