The Controller
You don't need a powerful microcomputer to drive this setup. We selected the Arduino for this project because of the excellent (and well documented) PID and autotune libraries available for it. The Adafruit RGB/LCD shield with integral pushbuttons was also perfect for hosting the user interface.To build this controller, you will need:
-
Arduino UNO
- Proto Shield or Wing Shield
- RGB LCD Shield (Positive or Negative display)
-
Power Switch Tail
-
High Temperature DS18B20 Temperature Sensor you can also use the standard Waterproof DS18B20 type if you aren't planning on heating it past 90C, which is very rare for Sous Vide
- Food Grade Heat-Shrink Tubing
- Servo Extension Cable
- In-Line JST power wire connector: Male and Female
You will also need some basic tools and soldering supplies:
- WIre cutters
- Wire strippers
- Soldering Iron
- Solder
- Shrink Wrap Tubing
- Small Phillips Screwdriver
