<li>背景介绍</li>
</ol>
<p>物联网技术是指通过互联网将各种设备、传感 器、控制器等连接在一起，形成一个能够实时互通信息的网络。物联网技术的基本原理是通过传感器采集设备产生的数据，并通过控制器进行处理和控制，最终将数据传输到互联网上，实现设备之间的智能交互。物联网技术的核心特点是实时性、数据共享、智能化和互联性。物联网技术的实时性意味着设备和传感器能够即时收集和传输数据，使得用户可以实时了解设备状态和环境情况。数据共享可 以使不同设备之间共享数据，实现更高效的资源利用和协同工作。智能化指的是物联网设备具备处理和分析数据的能力，可以根据用户需求自动调整设备工作模式。互联性表示物联网技术可以实现设备与设备、设备与人之间的无缝连接和交互，实现更强大的功能和用户体验。物联网技术广泛应用于智能家居、智能交通、智慧城市等领域，为人们的生活带来便利和智能化。</p>

<p>室内照明灯系统硬件如图2.1所示分，为三部分：基于ESP32 S3的服务端、基于ESP32 PICO的传感器端与小爱音箱。其中，ESP32 S3服务端使用的是乐鑫的ESP32 S3 LCD EV开发板。如图2.2所示，主要负责与小爱音箱通信，接收传感器端数据、LCD实时显示传感器数据以及灯光的控制；ESP32 PICO传感器端为单独设计的ESP32板卡，如图2.3所示，主要功能为采集MPU6050数据与SHT30数据应通过BLE传输到服务端；小爱音箱主要是与服务端实现语音交互功能。</p>
