【实例简介】MQTT 协议+W5500EVB+DHT11模拟实现了手机端可以在外网控制板载LED 灯的亮灭和实时接收 DHT11 采集到的数据，其中 W5500EVB 作为以太网网关，负责将采集 到的温湿度数据加上设定的主题按照 MQTT 协议的要求 PO 到 MQTT 云端，或者在订阅针 对 LED 灯开关控制的主题后从 MQTT 云端接收手机 APP 发过来的对应 LED 灯开关控制的 主题的控制指令。当然，现实的话大神们可以脑补一下用带有蓝牙或者 Zigbee 控制功能的 灯泡或家电设备，开发板这边也加上接收模块…这是后续需要完善的，手机 APP 怎么做的 下次有机会再讲，这次先把 MQTT 以太网网关怎么实现的，以及如何采集 DHT11 数据等方 法给大伙儿分享下。
