Code Example (Arduino):
```c
#include <WiFi.h>
#include <DHT.h>

const char ssid = "your_wifi_ssid";
const char password = "your_wifi_password";
const char apiKey = "your_api_key";

DHT dht(2, DHT11);

void setup() {
  Serial.begin(9600);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi");
  dht.begin();
}

void loop() {
  delay(10000);
  float temp = dht.readTemperature();
  float hum = dht.readHumidity();
  if (isnan(temp) || isnan(hum)) {
    Serial.println("Failed to read from DHT sensor!");
    return;
  }
  Serial.print("Temperature: ");
  Serial.print(temp);
  Serial.println(" C");
  Serial.print("Humidity: ");
  Serial.print(hum);
  Serial.println(" %");

// Send data to the cloud using your preferred API
  WiFiClient client;
  client.setServer("api.yourdomain.com", 80);
  client.print("GET /api/temperature?temp=");
  client.print(temp);
  client.print("&hum=");
  client.print(hum);
  client.print("&apikey=");
  client.print(apiKey);
  client.println(" HTTP/1.1");
  client.println("Host: api.yourdomain.com");
