Hi, I'm looking for information on how to build a circuit to control water temp in a heating chamber which will be circulating basically water through it. The chamber will be a 1.5" pipe with the element extending most of its length, fluid entering one end and exiting the other. I've found a lot of info on PIDs and studied them in school but wonder if anyone's done this with say a PIC chip or a laptop. Any info would be appreciated. Thanks
