WiFi LoRa简介
Beginner
在我们全面的 WiFi LoRa 入门课程中探索远距离无线通信的强大力量,您将学习如何在无需传统基础设施的情况下,从数英里之外管理设备和机器人。本实践课程重点介绍多功能 Heltec WiFi LoRa 32 模块,教您如何创建强大的离网系统,该系统可将数据传输到高达 13 英里(21 公里)的惊人距离。无论您是监控远程设备、控制偏远地区的设备,还是在无法使用传统 WiFi 和蜂窝服务的地区构建通信网络,本课程都能提供必要的技能,让您充分利用 LoRa 技术的独特功能。
通过实际操作项目,您将掌握如何实现各种应用,包括环境监测、远程控制系统和安全消息传递网络。本课程强调传输和接收技术,确保您能够构建完整的双向通信系统。您将使用 DHT22 等传感器进行温度监控、远程控制继电器和伺服器,甚至创建网状网络以扩大覆盖范围,同时了解使 LoRa 成为农业、安全、工业监控和紧急通信中低功耗、长距离应用的理想选择的基本原理。
