Sous Vide Controller

Arduino UNO based Sous Vide Controller. HMI, TFT and Arduino Code and library can be found here:



- Sleep Mode

- Two Pages: Monitor and Config

- Numeric Keypad

- Simple proportional temperature algorithm - I can't figure out PID

- Thermometer icon indicates when heater is turned on

- Nextion is connected via SoftSerial on pins 2,3

- Will support decimals when we finally get a decent font.  "25. 5" looks awful. 

The first controller I made used a rice maker connected to a relay. But the small size and lack of water circulation was limiting. So the next version will be a clip-on immersion heater with an aquarium bubbler as a circulator.
