摘要
随着智能家居理念的普及和节能意识的提升，照明系统的智能化与个性化控制成为改善生活品质、降低能源消耗的重要方向。传统照明系统多依赖手动开关和固定亮度模式，存在人走灯不灭、亮度与环境不匹配等问题，不仅造成能源浪费，也难以满足不同场景下的照明需求。
基于 STM32 的无线照明控制系统，以 STM32F103C8T6 单片机为核心，整合了 5516 光照检测模块、人体热释电传感器 D203S、红外遥控模块、按键、LED 照明装置及相关驱动电路，实现了照明的自动化调节与多元化控制。系统核心功能包括：通过 5516 模块实时监测环境光照强度，为亮度调节提供数据依据；通过 D203S 检测环境是否有人，当检测到有人且光照强度低于预设最大值时，根据光照值自动调节照明灯亮度，实现 “人来灯亮、亮度适配”；支持通过红外遥控器远程调节灯的亮度，适应不同用户的操作习惯；通过按键可手动控制灯的亮度，满足即时调节需求。
该系统的实现，有效提升了照明控制的智能化与节能性，通过人感与光感的协同作用避免了无效照明，同时提供了红外遥控与按键操作的多元化控制方式，为家庭、办公室等场景提供了便捷、高效的照明解决方案，同时为同类智能照明设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the rapid advancement of intelligent building technology, efficient and energy – saving lighting control has become an important part of modern architecture management. Traditional lighting systems, which rely on manual switching and fixed – brightness operation, not only result in a waste of energy but also fail to meet people’s needs for a comfortable lighting environment, making it difficult to adapt to the development trend of energy conservation and intelligence in public places and households.
The wireless lighting control system based on STM32 (Project No.: mcuclub – dz – 788), with STM32F103C8T6 as the core, integrates the 5516 light detection module, human body pyroelectric sensor D203S, infrared remote control module, buttons, and lighting execution equipment. It realizes automatic and intelligent control of the lighting environment. The core functions of the system include: the 5516 light detection module collects the ambient light intensity in real – time; the D203S sensor detects whether there is a person in the environment. When a person is detected and the light intensity is less than the set maximum value, the brightness of the lighting lamp is adjusted according to the light intensity; the infrared remote control can be used to adjust the lamp brightness remotely; buttons are provided to manually control the lamp brightness, enabling both automatic and manual control modes.
The implementation of this system effectively improves the energy efficiency of lighting control, reduces unnecessary energy consumption by automatically adjusting the brightness according to the presence of people and light conditions, and enhances the convenience of lighting control through multiple control methods. It provides an efficient and practical solution for energy – saving transformation of lighting systems in public places such as offices and corridors, and also offers a reference for the research and development of similar intelligent lighting equipment, with high practical application value.
