如何使用Java开发物联网硬件的湿度检测功能

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class HumiditySensor {
    public static void main(String[] args) {
        try {
            // 获取传感器数据
            int humidityData = getHumidityData();
           
            // 将数据发送到云端
            sendToCloud(humidityData);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static int getHumidityData() throws Exception {
        // 在这里编写代码，从传感器读取湿度数据
        // 返回一个整数型的湿度数值
    }

    private static void sendToCloud(int humidity) throws Exception {
        String endpoint = "https://your-cloud-api-endpoint";
        String apiKey = "your-api-key";
        
        // 将湿度数据发送到云端
        URL url = new URL(endpoint + "?humidity=" + humidity);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("GET");
        conn.setRequestProperty("apiKey", apiKey);
        
        BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String line;
        StringBuilder response = new StringBuilder();
        while ((line = rd.readLine()) != null) {
            response.append(line);
            response.append('');
        }
        rd.close();
        
        // 处理云端返回的响应数据
        // 在这里编写代码，根据需要对响应进行解析和处理
    }
}
