如何使用Java开发物联网硬件的土壤湿度检测功能

   import jssc.SerialPort;
   import jssc.SerialPortEvent;
   import jssc.SerialPortEventListener;
   import jssc.SerialPortException;

   public class SoilMoistureSensor {
       private static SerialPort serialPort;

       public static void main(String[] args) {
           serialPort = new SerialPort("/dev/ttyUSB0"); // 串口设备名，根据实际情况修改
           try {
               serialPort.openPort();
               serialPort.setParams(9600, 8, 1, 0);
               serialPort.addEventListener(new SerialPortEventListener() {
                   public void serialEvent(SerialPortEvent event) {
                       if (event.isRXCHAR()) {
                           try {
                               String receivedData = serialPort.readString();
                               int moisture = Integer.parseInt(receivedData.trim());
                               System.out.println("土壤湿度：" + moisture);
                           } catch (SerialPortException ex) {
                               System.out.println("Error in receiving data from serial port: " + ex);
                           }
                       }
                   }
               });
           } catch (SerialPortException ex) {
               System.out.println("Error in opening serial port: " + ex);
           }
       }
   }
