Human body sensing light is a good lighting device that can automatically turn on or off lights according to human activities, so it can achieve energy conservation and improve the convenience of living or working spaces. The research topics usually focus on improving sensing sensitivity, reducing false triggering rates, optimizing energy management, and enhancing user interaction experience. Research methods include hardware design, system integration, experimental testing, and performance evaluation. Researchers will choose suitable microcontrollers as core processing units, design circuits to integrate sensors (such as pyroelectric sensors, infrared sensors, etc.), and select suitable LED lighting fixtures as lighting components. The human body sensing light can be triggered at a distance of about 50cm from the person. This distance can be increased by adjusting the sensor, but the range will be reduced. The conclusion is that induction lamps have certain practical value, but their false triggering and insensitivity still exist, and further optimization is needed.
