On the PC side of the control would be the smarts to control temperatures and have various recipes for different temperature profiles.
These scenarios are common when smoking Control the cabinet temperature only. Control the cabinet temperature and when the internal temperature of the meat reaches a point change the cabinet temperature to the internal temperature just to maintain internal temperature and sound the general alarm! Control the cabinet temperature and ramp from one temp to the next over a given time span. Have recipe controlled time and temperatures. I do this now with a PLC with a thermocouple card and a touch screen interface but it is far from cheap... I've taken house air conditioner thermostats apart and made fermenter controllers with remote direct sensing of the temperature of the wort but it is a simple temperature setting for that. http://suburb.semo.net/jet1024/Controller.htm So I'm well aware of the $10 temperature controllers. It doesn't have to be fast, just be able to get the temperature info to the PC and be able to switch on and off some SSR's.
