摘要
随着智能家居行业的快速发展和人们对舒适节能生活的追求，智能化的光照控制成为提升家居体验的重要环节。传统的照明系统多依赖手动开关，无法根据环境光照和人员活动自动调节，不仅使用不便，还存在能源浪费的问题，难以满足现代家居的智能化需求。
基于 STM32F103C8T6 单片机的自适应光照调节及其蓝牙语音家居灯控制系统，整合了光敏电阻 5516、人体热释电 D203S 模块、语音识别模块 SU-03T、按键、蓝牙模块 ECB02 及 OLED 显示屏等硬件，实现了多项核心功能：通过光敏电阻检测环境光照强度；借助人体热释电模块检测人员活动，有人时根据光照强度自动调节灯光（过亮时关灯、过暗时最亮、适中时自适应调亮）；通过语音识别模块和蓝牙模块实现灯光开关的语音与远程控制；利用按键设置光照阈值，OLED 显示屏实时显示光照强度、灯光亮度及控制模式。
该系统的实现，有效提升了家居照明的智能化和节能性，减少了人工操作，确保了光照环境的舒适性与合理性，为智能家居照明控制提供了高效、便捷的解决方案，同时也为类似智能控制设备的研发提供了有益参考，具有一定的实际应用价值。

ABSTRACT
With the rapid development of the smart home industry and people’s pursuit of a comfortable and energy-saving life, intelligent lighting control has become an important part of improving the home experience. Traditional lighting systems mostly rely on manual switches and cannot automatically adjust according to ambient light and personnel activities. This is not only inconvenient to use but also causes energy waste, making it difficult to meet the intelligent needs of modern homes.
The STM32F103C8T6 single-chip microcomputer-based adaptive lighting adjustment and Bluetooth voice home lighting control system integrates hardware such as photoresistor 5516, human pyroelectric D203S module, voice recognition module SU-03T, buttons, Bluetooth module ECB02, and OLED display, and realizes several core functions: detecting ambient light intensity through the photoresistor; using the human pyroelectric module to detect personnel activities, and when there are people, automatically adjusting the light according to the light intensity (turning off the light when it is too bright, making it the brightest when it is too dark, and adaptively dimming when it is moderate); realizing voice and remote control of the light switch through the voice recognition module and Bluetooth module; setting light thresholds with buttons, and the OLED display real-time showing light intensity, light brightness and control mode.
The realization of this system effectively improves the intelligence and energy efficiency of home lighting, reduces manual operations, ensures the comfort and rationality of the lighting environment, provides an efficient and convenient solution for smart home lighting control, and also provides a useful reference for the research and development of similar intelligent control equipment, which has certain practical application value.
