帮我写一个基于arduino UNO开发板，使用dth11采集温湿度数据，并通过ESP8266-01sWiFi模块将温湿度数据上传至阿里云端

要基于Arduino Uno开发板使用DHT11传感器采集温湿度数据并通过ESP8266-01S WiFi模块上传到阿里云，你需要遵循以下步骤：

1. **硬件准备**：
- Arduino Uno开发板
- DHT11温度湿度传感器
- ESP8266-01S WiFi模块
- 电线、面包板和连接线

2. **软件库安装**：
- 在Arduino IDE中，你需要安装`DHT`库（用于DHT11通信）和`PubSubClient`库（用于WiFi和HTTP通信）。你可以从官方网站下载或通过IDE的Sketch -> Include Library -> Manage Libraries...功能安装。

3. **编写主程序**：

   #include <DHT.h>
   #include <ESP8266WiFi.h>
   #include < PubSubClient.h>

   // 传感器的连接信息
   const int dhtPin = D4; // DHT11的数据引脚
   const char* ssid = "your_SSID";
   const char* password = "your_PASSWORD";

   // 阿里云物联网平台的设备标识和API密钥
   const char* deviceName = "your_device_name";
   const char* aliyunTopic = "iot_topic"; // 云端主题
   const char* aliyunHost = "物联管理控制台URL"; // 例如"http://yunmqtt.cn-shanghai.aliyuncs.com"

   DHT dht(dhtPin);
   WiFiClient client;
   PubSubClient esp(client, WiFi.localIP());

   void setup() {
     Serial.begin(9600); // 初始化串口通信
     delay(10); // 等待串口稳定
     if (WiFi.mode(WIFI_STA) != WL_CONNECTED) {
       Serial.println("Connecting to WiFi...");
       WiFi.begin(ssid, password);
       while (WiFi.status() != WL_CONNECTED) {
         delay(500);
         Serial.print(".");
       }
       Serial.println("");
       Serial.println("Connected to WiFi");
     }

     // 设置阿里云设备和主题
     mqtt_setServer(aliyunHost, 1883);
     mqtt_setCallback(callbackFunction);
   }

   void loop() {
     if (!esp.connected()) {
       reconnect();
     } else {
       dht.begin(); // 启动DHT11
       float temperature, humidity;
       if (dht.readTemperature(&temperature) && dht.readHumidity(&humidity)) {
         String data = "temp=" + String(temperature) + "," + "humidity=" + String(humidity);
         publishToCloud(data);
       }
       dht.end(); // 关闭DHT11
       delay(10 * 1000); // 每隔10秒读取一次数据
     }
   }

   // MQTT回调函数
   void callbackFunction(char* topic, byte* payload, unsigned int length) {
     Serial.println(topic);
     Serial.print("Payload received: ");
     for (int i = 0; i < length; i++) {
       Serial.print((char)payload[i]);
     }
     Serial.println();
   }

   // 连接并重试机制
   void reconnect() {
     while (!esp.connect(deviceName)) {
       delay(5000);
       Serial.println("Attempting MQTT connection...");
     }
     subscribeToCloud();
   }

   // 发布数据到云端
   void publishToCloud(String data) {
     static char msgBuffer[256];
     strcpy(msgBuffer, "devices/" + deviceName + "/data/");
     strcat(msgBuffer, data.c_str());
     if (esp.publish(aliyunTopic, msgBuffer, true)) { // 发送并确认消息
       Serial.println("Data published.");
     } else {
       Serial.println("Publish failed.");
     }
   }

   // 订阅云端主题
   void subscribeToCloud() {
     if (esp.subscribe(aliyunTopic) == ESP_OK) {
       Serial.println("Subscribed to topic!");
     } else {
       Serial.println("Subscribe failed.");
     }
   }
