" Beginning LoRa Radio Networks with Arduino 是一本由 Pradeeka Seneviratne 编著的技术书籍,旨在引导读者通过 Arduino 创建自己的 LoRa 无线项目,适用于非工业用途,深入理解 LoRa 技术、LoRaWAN 和 LPWAN。书中涵盖了从建立第一个 LoRa 无线通道到构建 LoRa 网关网络、使用 RESTful API 和 MQTT 协议与 IoT 服务器通信以及实时 GPS 跟踪等各种实践项目。" 在物联网(IoT)领域,LoRa(Long Range)是一种低功耗广域网(LPWAN)技术,它提供了远距离通信能力,特别适合于需要长距离传输和低功耗的应用。本书 "Beginning LoRa Radio Networks with Arduino" 提供了一个实践性的入门教程,利用易于获取且价格适中的硬件,结合 Arduino 开发环境进行项目构建。 LoRa 技术的核心在于其独特的扩频调制技术,称为 Chirp Spread Spectrum (CSS),这使得它能在低功率下实现远距离通信,同时保持较好的抗干扰性。LoRaWAN 是基于 LoRa 的一种网络协议栈,它定义了网络架构、安全性和网络管理等方面,允许设备连接到一个或多个网关,进而与后端服务器进行通信。 在本书中,读者将学习如何设置 LoRa 网络,包括建立网关,这是连接 LoRa 设备和互联网的关键组件。此外,通过使用 RESTful API,可以与 IoT 服务器交互,实现数据的上传和处理。RESTful API 是一种轻量级的接口设计方法,易于理解和实现。MQTT(Message Queuing Telemetry Transport)是一种面向物联网的发布/订阅消息协议,适合低带宽、高延迟或不可靠的网络环境。 书中的项目还包括实时 GPS 追踪,这对于智能物流、个人跟踪和资产管理等应用至关重要。LoRa 的低功耗特性使其非常适合用于长期运行的远程追踪设备。 通过本书,读者不仅能掌握 LoRa 的基本原理,还能了解到如何将其应用于智能农业、智慧城市、智能环境、智能医疗、智能家居和建筑、智能工业控制、智能计量以及智能供应链和物流等多个领域。这是一本对想要探索 LoRa 无线网络的 Arduino 爱好者和开发者非常有价值的参考资料,帮助他们构建长距离、低功耗的无线 IoT 网络。
