Heater Control

I'm looking to sense the cabinet temperature of my smoker as well as the internal temperature of what I'm smoking and control a heater based on the recipe I pick. For example I might want a cabinet temperature of 160 until the IT reaches 140 then change the cabinet temperature to 140.

My goal is to have a low cost system that is connected to a PC and the PC is the GUI interface and/or program.

Is the Arduino Uno the tool I need to go between the thermocouple chips MAX6675 and the PC?

Do you use a shield board to mount the MAX6675 chips and other items on?

Thanks

Do a forum search for "smoker" "grill", and "bbq" for previous discussions of similar projects.

Here is a link to I think exactly what you want to do. look at his wiring schematic link for more information. i think this will do it for you.

In the following schematic it shows the Arduino directly controlling a SSR. Is this possible or is something missing?
