Intro: Arduino Thermocouple Sous Vide Controller
This project makes use of and builds on the previous projects. After completing this project, you can use a low-cost crock-pot as a precision temperature controlled Sous Vide cooker.
In upgrading this project, I added a 0 - 5vdc panel meter from Sparkfun, a 'power tail' from Adafruit (which can safely switch 120 vac using 5 vdc relay output from Arduino), and software changes necessary to support Sous Vide usage.
Here's a link to the project. link to Arduino Thermocouple Based Sous Vide Controller.
