Sous-vide Arduino Shield

*NOTE* THIS PROJECT IS DONE BY A GROUP OF STUDENTS FROM SINGAPORE POLYTECHNIC

Sous-vide (/suːˈviːd/; French for “under vacuum”)[1] is a method of cooking food sealed in airtight plastic bags in a water bath for a long time—72 hours in some cases—at an accurately determined temperature much lower than normally used for cooking, typically around 60 °C (140 °F). The intention is to cook the item evenly, not overcook the outside while still keeping the inside at the same ‘doneness’ and to keep the food juicier.

AC Power Control
Code for Arduino
Experiment on Sousvide  Arduino Shield

Step 1:

DIY Sousvide Arduino Shield

Solder the following components into an Arduino Sousvide Shield as shown:
2×16 LCD x 1
RGB x 1
LM35 Temperature Sensor x 1
Sparkfun Solid State Relay (SSR) Control x 1
1K ohm Resistors x 6
Push Buttons x 3

Purpose of the components:
Arduino Uno – Prototyping platform for testing
LCD – Display results (eg. temperature)
RGB – Visual signal
LM35 Temperature Sensor – Detect temperature
SSR – Electronic switching device in which a small control signal controls a larger load current or voltage
Push Buttons – Settingsous-vide schematics.xls34 KB  

Step 2:

AC Power Control

Circuit Sous-vide Arduino Shield

1. Wire the AC plug to the AC Face Plate with the live pin as shown

2. The live pin will then be connected to the SSR
