I made a web server to monitor Temp and switch on off IR snd RF devices

Hi, I m attaching my sketch here. The sketch is working fine and I am able to control my IR devices and RF devices. I m using LM 35 to monitor temp. I m able to control MY HVAC and other IR and RF devices. Now when I add more devices I fell short of SRAM. Can anybody look at the code and do some correction so that SRAM is minimized.I dont know programming I just copied the sketch and modified for my purpose.I am using arduino Uno and w5100 ethernet shield.

I dont see your sketch but this example should help you littlebit:

client.println(F("<H1>Header</H1>"));
client.println(F("<button onclick=\"location.href='http://192.168.1.40/?onoff'\">ON/OFF</button>"));client.println(F("
"));
