摘要
随着生活品质的提升和智能家居理念的普及，家居照明的便捷性、智能化成为人们追求舒适生活的重要需求。传统家居灯光控制多依赖手动开关，存在操作不便、功能单一等问题，难以满足不同场景下的照明需求，例如夜间起夜时需手动开灯、无法远程控制灯光状态等，影响生活体验。因此，研发一种功能丰富、操作便捷的智能化家居灯控制系统十分必要。
本设计提出了一种基于 STM32F103C8T6 单片机的智能家居灯系统。系统主要功能包括：通过 3 个 LED 灯模拟卧室、客厅、洗手间的照明；借助 3 个按键分别控制三个灯的亮灭；在洗手间安装 D203S 人体热释电感应模块，当检测到有人且 5516 光敏电阻检测到光线较低时，自动开启洗手间灯；通过按键可调节客厅灯的亮度；通过按键设定卧室灯亮灯时间，时间到达后自动熄灭，OLED 显示屏实时显示计时时间；通过 ECBO2 蓝牙模块连接手机端，实现手机对三个灯亮灭的控制及客厅灯亮度的调节；通过 SU-03T 语音识别模块控制三个房间灯的开关和客厅灯的亮度。
该智能家居灯系统的作用在于，为人们提供了一种便捷、智能的家居照明解决方案。通过多种控制方式的融合与自动化感应功能，提升了家居照明的舒适度与便捷性，满足不同场景下的照明需求，改善生活品质。

Smart Home Light Based on Single Chip Microcomputer
Abstract
With the improvement of quality of life and the popularization of smart home concepts, the convenience and intelligence of home lighting have become important demands for people to pursue a comfortable life. Traditional home lighting control relies heavily on manual switches, which have problems such as inconvenient operation and single functionality, making it difficult to meet the lighting needs in different scenarios. For example, manual turning on of lights at night and inability to remotely control lighting status can affect the living experience. Therefore, it is necessary to develop an intelligent home light control system that is feature rich and easy to operate.
This design proposes an intelligent home lighting system based on STM32F103C8T6 microcontroller. The main functions of the system include: simulating the lighting of the bedroom, living room, and bathroom through three LED lights; Use three buttons to control the on/off of three lights respectively; Install D203S human pyroelectric induction module in the bathroom. When someone is detected and the 5516 photoresistor detects low light, the bathroom light will automatically turn on; The brightness of the living room lights can be adjusted through buttons; Set the bedroom light on time by pressing the button, and it will automatically turn off when the time is up. The OLED display screen will show the timer time in real time; Connect the ECBO2 Bluetooth module to the mobile phone to control the on/off of three lights and adjust the brightness of the living room lights; Control the on/off of three room lights and the brightness of the living room lights through the SU-03T speech recognition module.
The function of this smart home lighting system is to provide people with a convenient and intelligent home lighting solution. Through the integration of multiple control methods and automated sensing functions, the comfort and convenience of home lighting have been improved, meeting the lighting needs in different scenarios and enhancing the quality of life.
