摘 要
随着智能家居技术的普及与节能环保需求的提升，传统照明系统因缺乏智能化控制导致的能耗浪费和使用不便问题日益凸显。本研究提出一种基于单片机的人体智能感应灯设计方案，旨在实现照明系统的自动化、人性化控制，降低能源消耗。该系统以STM32单片机为核心控制器，结合红外热释电传感器和光敏电阻模块，实现了人体检测、环境光感知与智能调光的功能。系统通过红外传感器实时捕捉人体活动信号，结合光敏电阻反馈的环境光照强度数据，采用阈值判断与延时控制算法，驱动RGB灯具在有人且光线不足时自动点亮，并在无人或光照充足时关闭或调暗。
基于单片机的人体智能感应灯设计实现了以下功能：通过5516光照检测模块实时监测环境光照强度，并根据光照强度自动调节灯具亮度；利用D203S人体热释电感应模块检测是否有人存在，实现人来灯亮、人走灯灭的节能控制；通过DS1302时钟模块获取当前时间，根据不同时间段自动调节色温；借助SU-03T语音识别模块实现语音控制亮度和色温；同时，通过按键设置光照的最大值和最小值、时间、色温和亮度，并通过OLED显示模块实时显示当前状态。
通过实物制作与测试，达到照明系统的自动化、人性化控制，降低能源消耗。

With the popularization of smart home technology and the improvement of energy conservation and environmental protection needs, the waste of energy consumption and inconvenience caused by the lack of intelligent control of traditional lighting systems have become increasingly prominent. In this study, a design scheme of human intelligent sensor lamp based on single-chip microcomputer was proposed, which aimed to realize the automatic and humanized control of the lighting system and reduce energy consumption. The system uses STM32 microcontroller as the core controller,combined with infrared pyroelectric sensor and photoresistor module, to realize the functions of human body detection,ambient light perception and intelligent dimming. The system captures human activity signals in real time through infrared sensors,combines the ambient light intensity daa fed back by the photoresistor, and uses threshold judgment and delay control algorithms to drive LED lamps to automatically light up when there are people and the light is insufficient, and turn off or dim when thee is no one or the light is sufficient."
The design of human intelligent induction lamp based on MCU realizes the following functions: real-time monitoring of environmental illumination intensity through the 5516 illumination detection module, And automatically adjust the intensity of the lamps according to the lighting intensity; Using the D203S human pyroelectric induction module to detect the presence of a human being, Realize the energy saving control of the light and the light; Get the current time through the DS1302 clock module, Automatic adjust the color temperature according to different time periods; With the help of SU-03T speech recognition module to control brightness and color temperature; at the same time, Set the maximum and minimum value, time, color temperature and brightness, And display the current state in real time through the OLED display module.
Through the development and testing of physical prototypes, the lighting system achieves automated and user-friendly control, thereby reducing energy consumption.
