一、设计背景和意义
1.1设计背景
随着“智能家居”理念的广泛普及以及物联网、嵌入式系统等前沿技术的发展，传统家居照明产品正经历着由“人工控制”向“智能联动”“自动响应”转变的深刻变革。作为家庭和办公场景中使用频率极高的照明设备，台灯的功能和体验也正在被重新定义。传统台灯产品普遍存在照度不可调、能耗高、操作方式单一、缺乏人性化设计等问题，无法满足当代用户对“舒适、健康、节能、智能”照明体验的多重需求，尤其对于长时间用眼的学生和办公人群来说，缺乏动态调光、护眼提醒等功能更是隐患重重。
1.2设计意义
该系统通过集成DHT11环境温湿度传感器、光敏电阻、HC-SR04超声波测距模块、AS312人体感应模块以及DS1302时钟模块，能够实时监测用户周围环境状况及使用行为，从而在不同模式下自动判断灯光状态是否需要开启并调节至合适亮度，在实现节能照明的同时，也提升了用眼健康与使用便捷性。此外，系统通过ESP8266 WiFi模块接入机智云平台，使用户能够随时随地通过手机APP控制灯光设备，并远程查看环境数据及历史记录，提升了系统的人机交互体验与实用性。
从学术研究的角度来看，本课题综合了嵌入式软硬件设计、物联网通信、自动控制、传感器应用等多个知识点，体现了计算机科学与现代智能硬件工程融合的特点，具有较强的技术综合性和工程实现价值。对于培养学生系统开发能力、动手实践能力和工程创新思维具有积极意义。
