Sous-Vide Cooking Temperature Plus Kit with Arduino Uno + Relay
Precision Sous-Vide Cooking Controller Kit with Arduino Uno & Relay — Timed Water Bath Heating
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit transforms an Arduino Uno into a precise sous-vide water bath controller. You set a start time so the water reaches the perfect cooking temperature exactly when you need it—then the relay cuts off automatically. It’s a practical Smart Home & Living project that brings restaurant-quality cooking to the home kitchen, and it doubles as an impressive submission for CBSE Class 12 physics or B.Tech ECE assignments.
What You'll Build
You’ll assemble a system that reads water temperature with a waterproof DS18B20 sensor, tracks real time with a DS3231 RTC, and switches a 5V relay to control a heater. The 16x2 LCD shows current temperature, target setpoint, and timer countdown. Three tactile buttons let you scroll menus to set the desired temperature and start time. Once the timer expires, the heater relay opens, preventing overcooking and saving energy. This programmable water bath controller is your first step toward automated sous-vide cooking.
What You'll Learn
- Interface a DS18B20 waterproof temperature sensor via OneWire protocol
- Set up a DS3231 real-time clock for accurate timekeeping and alarm triggering
- Drive a 5V relay module safely to switch resistive heating elements
- Display sensor data and countdown on a 16x2 LCD using an I2C backpack

Who This Kit Is For
This kit is designed for intermediate learners comfortable with Arduino. CBSE Class 11-12 students can use it for physics investigatory projects on thermal control or computer science practicals on embedded scheduling. B.Tech ECE/EEE undergraduates can prototype a timed appliance controller for Smart India Hackathon or minor project submissions. ATL Tinkering Labs and hobbyists exploring home automation will appreciate how it blends temperature sensing, real-time clock, and relay logic in one working device.
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 on the box to access our AI companion tailored to this kit; it guides you step by step. Real human help is available on WhatsApp for any edge cases.
Can I use this to switch a 230V AC heater?
Yes, the 5V relay module handles up to 250V 10A AC loads. We include 1N4007 flyback diodes and safety notes; ensure you follow proper insulation and enclosure practices for mains voltage.
Does the clock keep time when power is removed?
Absolutely. The DS3231 RTC has a CR2032 battery backup (included). It will hold accurate time for years even if the Arduino is unplugged, so your cooking schedules persist.
What temperature range can the DS18B20 measure?
The waterproof DS18B20 covers -55°C to 125°C with ±0.5°C accuracy, perfectly covering sous-vide cooking temperatures (typically 50–85°C). It’s also suitable for hot water shower automation if you adapt the code.
Cooking — DS18B20 and RTC control heater relay to heat water before shower time then cut off.
