摘要
随着智能化生活的不断推进，室内照明的精准控制对于提升能源利用效率、营造舒适生活环境具有重要意义。传统的人工开关灯方式不仅依赖人为操作、响应不及时，还存在能源浪费、光照调节不便等问题，难以满足现代化、智能化室内照明的需求。
基于 STM32F103C8T6 单片机的室内无线照明设备控制系统，整合了人体热释电传感器、光照监测模块、时钟模块、按键、OLED 显示屏、蓝牙模块及执行设备（照明灯等），实现了室内照明的自动化监测与智能调控。系统核心功能包括：通过人体热释电传感器监测当前环境是否有人，监测到有人时照明打开，无人时关灯；借助光照监测模块监测当前环境的光照强度，当光照大于设置的最大值时，关闭灯光，当光照小于最大值且有人时，根据光照强度控制照明灯亮度；通过时钟模块获取当前时间，可设置开关灯时间，仅在开灯时间内监测到有人且光照小于最大值时才开灯；支持通过按键设置光照最大值、开关灯时间以及灯的亮度和颜色调节；通过 OLED 显示屏实时显示光照强度、是否有人、时间、色温和亮度等信息；利用蓝牙可以控制灯的亮度和颜色。
该系统的实现，有效提高了室内照明控制的自动化与智能化水平，减少了人为操作，降低了能源消耗，为营造舒适、节能的室内环境提供了高效、可靠的解决方案，同时为同类室内照明控制设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the continuous advancement of intelligent life, precise control of indoor lighting is of great significance for improving energy utilization efficiency and creating a comfortable living environment. Traditional manual light switching methods not only rely on human operation with untimely responses but also have problems such as energy waste and inconvenient light adjustment, making them difficult to meet the needs of modern and intelligent indoor lighting.
The indoor wireless lighting equipment control system based on the STM32F103C8T6 microcontroller integrates human body pyroelectric sensors, light monitoring modules, clock modules, buttons, OLED displays, Bluetooth modules and executive devices (lighting lamps, etc.), realizing automatic monitoring and intelligent control of indoor lighting. The core functions of the system include: monitoring whether there is someone in the current environment through the human body pyroelectric sensor, turning on the lighting when someone is detected, and turning off the lights when no one is present; monitoring the light intensity of the current environment through the light monitoring module, turning off the lights when the light intensity is greater than the set maximum value, and controlling the brightness of the lighting according to the light intensity when the light intensity is less than the maximum value and there is someone; obtaining the current time through the clock module, which can set the light on and off time, and only turning on the light when someone is detected and the light intensity is less than the maximum value within the light on time; supporting the setting of the maximum light intensity, light on and off, and adjustment of light brightness and color through buttons; displaying light intensity, presence of people, time, color temperature and brightness in real-time through the OLED display; controlling the brightness and color of the light through Bluetooth.
The implementation of this system effectively improves the automation and intelligence level of indoor lighting control, reduces manual operation, lowers energy consumption, provides an efficient and reliable solution for creating a comfortable and energy-saving indoor environment, and also offers a reference for the research and development of similar indoor lighting control equipment, with high practical application value.
