Intro: Sous-vide Arduino Shield*NOTE* THIS PROJECT IS DONE BY A GROUP OF STUDENTS FROM SINGAPORE POLYTECHNIC

Sous-vide (/su˕ˈviË•d/; 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 socases—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 evenlyovercook the outside while still keeping the inside at the same 'doneness' and to keep the food juicier.

Items needed:Arduino Uno x 12x16 LCD x 1RGB x 1LM35 Temperature Sensor x 1Sparkfun Solid State Relay (SSR) Control x 11K ohm Resistors x 6

Push Buttons x 3Vacuum Pump x 1Electrical Heating Appliance x 1AC Face Plate x 1AC Plug x 1

Skills Needed:Soldering skillBasic electrical engineering skill

Overview:DIY Sousvide Arduino ShieldAC Power ControlCode for ArduinoExperiment on Sousvide Arduino Shield

Step 1:DIY Sousvide Arduino Shield

Solder the following components into an Arduino Sousvide Shield as shown:2x16 LCD x 1RGB x 1LM35 Temperature Sensor x 1Sparkfun Solid State Relay (SSR) Control x 11K ohm Resistors x 6Push Buttons x 3

Purpose of the components:

Arduino Uno - Prototyping platform for testingLCD - Display results (eg. temperature)RGB - Visual signalLM35 Temperature Sensor - Detect temperatureSSR - Electronic switching device in which a small control signal controls a larger load current or voltagePush Buttons - Setting

File Downloads

sous-vide schematics.xls (34 KB)[NOTE: When saving, if you see .tmp as the file ext, rename it to 'sous-vide schematics.xls']

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!!!
