Sous-Vide Temperature Pro Kit with Arduino Uno & Relay - Advanced STEM Project
Sous-Vide Cooking Temperature Pro Kit with Arduino Uno & Relay - Master Ion Diffusion Control
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Calibrate the rate at which ions cross a semi-permeable membrane under precisely controlled temperatures - just like professional food scientists perfecting sous-vide techniques. This kit turns a cooking curiosity into a high-precision engineering experiment, letting you plot diffusion kinetics versus setpoint temperature using dual TDS probes and a relay-driven heater control loop. Every data point gets time-stamped by the DS3231 RTC and saved to a microSD card for lab-report analysis.
What You'll Build
A temperature-regulated test chamber that logs TDS/EC readings from two probes placed on opposite sides of a membrane, correlating diffusion rate with temperature setpoints. The system uses a 5V relay to switch an external heating element, while the OLED displays live conductivity values, elapsed time, and heater status. A microSD module stores timestamped data for later analysis in any spreadsheet software.
What You'll Learn
- Calibrate TDS/EC sensors to accurately track ion concentration changes over time
- Implement a relay-based control loop to maintain stable temperature setpoints
- Record time-series sensor data using an RTC and microSD module for offline analysis
- Analyze diffusion kinetics by plotting conductivity versus temperature across a membrane

Who This Kit Is For
Designed for B.Tech ECE/EEE students tackling Smart India Hackathon challenges, this kit provides a ready-to-build platform for sensor fusion and process control experiments. It is also ideal for ATL Tinkering Labs running advanced STEM workshops and for IIT/NIT/VIT final-year projects exploring food science instrumentation or chemical engineering diffusion studies.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to launch the AI companion, which walks you through troubleshooting exactly this circuit. If you still need help, reach out on WhatsApp and we'll reply within hours.
What type of membrane is recommended for diffusion experiments?
Common dialysis tubing or cellophane sheets work perfectly; they are not included but are available at most school lab suppliers or science shops.
Can I log data without an SD card?
The OLED will show live values and the RTC timestamps, but for a full CSV log you must insert a microSD card (not included) into the module.
Is the heating element included?
No, the relay switches an external 5V/12V heater; we recommend a PTC heating pad for safety and easy control.
Cooking - TDS EC sensor tracks ion diffusion rate across a membrane at different temperatures controlled by heater relay.
