帮我写一个用ESP32-S3开发板连接DHT11测量温湿度的程序

好的，我可以为您提供一个基本的示例程序：

#include <WiFi.h>
#include <WiFiClient.h>
#include <WiFiServer.h>
#include <WiFiUdp.h>
#include <HTTPClient.h>
#include <Adafruit_Sensor.h>
#include <DHT.h>

#define DHTPIN 4          // 定义DHT11连接的引脚
#define DHTTYPE DHT11     // 定义传感器类型为DHT11

DHT dht(DHTPIN, DHTTYPE);

const char* ssid = "your_SSID";       // 修改为您的WiFi信息
const char* password = "your_PASSWORD";

const char* serverName = "http://your_server.com/data_receiver.php";  // 修改为您的服务器地址和文件名

void setup() {
  Serial.begin(115200);
  dht.begin();
  WiFi.begin(ssid, password);

  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi..");
  }

  Serial.println("Connected to WiFi.");
}

void loop() {
  float temperature = dht.readTemperature();   // 读取温度数据
  float humidity = dht.readHumidity();         // 读取湿度数据

  if (isnan(temperature) || isnan(humidity)) { // 如果读数失败
    Serial.println("Failed to read from DHT sensor!");
    return;
  }

  Serial.print("Temperature: ");
  Serial.print(temperature);
  Serial.print(" °C\n");
  Serial.print("Humidity: ");
  Serial.print(humidity);
  Serial.println(" %");

  if (WiFi.status() == WL_CONNECTED) {         // 如果WiFi连接成功
    HTTPClient http;
    String data = "temperature=" + String(temperature) + "&humidity=" + String(humidity);  // 组装POST数据
    Serial.print("Posting data: ");
    Serial.println(data);

    http.begin(serverName);
    http.addHeader("Content-Type", "application/x-www-form-urlencoded");  // 设置POST数据类型
    int httpResponseCode = http.POST(data);   // 发送POST请求

    if (httpResponseCode > 0) {
      Serial.print("HTTP Response code: ");
      Serial.println(httpResponseCode);
    } else {
      Serial.print("Error sending data to server. HTTP Response code: ");
      Serial.println(httpResponseCode);
    }

    http.end();  // 关闭HTTP连接
  } else {
    Serial.println("WiFi not connected!");
  }

  delay(1000); // 等待1秒后重新读取数据
}

您需要根据实际情况修改程序中的WiFi连接信息和服务器地址。如果您没有自己的服务器，可以在本地搭建一个简单的服务器，收集来自ESP32-S3的数据。
