Introduction: Sous-vide Arduino Shield
*NOTE* THIS PROJECT IS DONE BY A GROUP OF STUDENTS FROM SINGAPORE POLYTECHNIC
The tools and components were provided by our FYP supervisor Teo Shin Jen.
Sous-vide (/suËËviËd/; 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.

Overview:
DIY Sousvide Arduino Shield
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:
2x16 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 - Setting
Attachments
Step 2:
AC Power Control
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
Step 3:
Code for Arduino
1. Download Arduino software from http://arduino.cc/en/Main/Software
2. Download PIDv1 library from http://arduino.cc/playground/Code/PIDLibrary
3. Add "PID_v1" folder to Drive:/<directory>/arduino-1.0/libraries
4. Run Arduino software
5. Copy code from https://snipt.net/sourjuice87/ssr/?key=08329317010a7ff6e87232cbcfed4a8c
6. Verfiy and upload
Step 4:
Experiment on Sousvide Arduino Shield
1. Preparation of food with vacuum pump
- Place your ingredients into a ziplock bag
- Use a vacuum pump to vacuum seal the ziplock bag
2. Electrical heating appliance
- Fill an electrical boiler or cooker with water
3. Waterproof LM35 temperature sensor
- Place the LM35 temperature into a straw
- Seal the both end of the straw
4. Set up DIY sousvide
- Hook up Arduino Uno with the DIY Arduino Sousvide Shield and run the code
- Place the waterproofed LM35 temperature sensor into the electrical heating applicance which is filled with water
- Submerge the vacuum sealed ziplock bag which contain ingredients into the water bath
5. Ready for COOKING!!!
