传感器收集数据通过以太网上传到客户端，遇到些困难。
各位大神好，麻烦请教个问题，我把红外定位探测头与Ethernet W5200 和UNO板连接在一起，想实现：探测到测到数据之后将数据后将数据通过以太网，将W5200作为服务器，电脑作为客户端，传输到客户端，可以通过WEB网页来查看传感器数据，这样的功能。但是程序写好之后，访问浏览器，浏览器迟迟打不开，串口能显示部分数据。#include <SPI.h>

这个是程序，请各位大神帮忙看看是什么问题？
// give the web browser time to receive the data
delay(1);
// close the connection:
client.stop();
Serial.println("client disonnected");
看看这段代码的delay 改成 delay（100）之类的。看看是否有帮助。
