uno+w5100+乐联+sht1x 远程监控温湿度的问题

liule126

如题，搭建一个远程监控的小系统，但是数据始终上传不到乐联网，串口显示“connect failed”。以下是代码和串口的显示，各位大神帮帮忙分析一下哪里错误了，是网络不通还是程序有问题啊
跪谢！！！
------------------代码：
/*

#include <LeweiClient.h>
#include <SPI.h>
#include <Ethernet.h>
#include <SHT1x.h>
#define LW_USERKEY "2c0e0a9e27d64c7f96b73a1e285c93b4"
#define LW_GATEWAY "01"
#define dataPin  6
#define clockPin 7

IPAddress ip(10,33,52,241);

IPAddress subnet(255,255,255,0);

LeWeiClient *lwc;


void setup() {
   // start serial port:
   Serial.begin(9600);
   // hope no exception here
   Serial.println("Starting up");
   //lwc = new LeWeiClient(LW_USERKEY, LW_GATEWAY);
   lwc = new LeWeiClient(LW_USERKEY, LW_GATEWAY,ip,mydns,gw,subnet);
}

void loop() {
   // read the analog sensor:
   //int sensorReading = analogRead(A0);  
  float temp_c;
  //float temp_f;
  float humidity;
  temp_c = sht1x.readTemperatureC();
  //temp_f = sht1x.readTemperatureF();
  humidity = sht1x.readHumidity();
  Serial.print("Temperature: ");
  Serial.print(temp_c, DEC);
  Serial.print("C / ");
  //Serial.print(temp_f, DEC);
  //Serial.print("F. Humidity: ");
  Serial.print(humidity);
  Serial.println("%");
  // if there's incoming data from the net connection.
   // send it out the serial port.  This is for debugging
   // purposes only:

  if (lwc) {
    Serial.print("*** start data collection ");
   
    //t1,t2.. must using the same name setting on web server.
    lwc->append("GGT1", temp_c);
    lwc->append("GGH1", humidity);
    Serial.print("*** data send ***");
    lwc->send();
    //Grammar changed by Wei&Anonymous ;)
    Serial.print("*** send completed ***");

   delay(POST_INTERVAL);
   }
}
串口反馈的信息，总显示connect failed
串口信息：
Starting up
Temperature: 27.8799972534C / 28.13%
*** start data collection append:{"Name":"GGT1","Value":"27.88"},
append:{"Name":"GGH1","Value":"28.13"},
*** data send ***connect failed!
*** send completed ***
