ESP8266-01S + Arduino 接入阿里云物联网平台

esp8266-01s接入物联网

1.创建产品

 

 2.创建设备

 

 3.打开arduino 编写代码

 

#include <ESP8266WiFi.h>
/* 依赖 PubSubClient 2.4.0 */
#include <PubSubClient.h>
#include <ArduinoJson.h>

/* 连接您的WIFI SSID和密码 */
#define WIFI_SSID         "wifi名称"
#define WIFI_PASSWD       "wifi密码"

/* 线上环境域名和端口号 */
#define MQTT_SERVER       "地址"
#define MQTT_PORT         1883 //端口号
#define MQTT_USRNAME      "用户名"
#define CLIENT_ID         "client ID"
#define MQTT_PASSWD       "密码"

//发布消息用的topic
