Build Accurate Sous-Vide Cooking Temperature Control with Arduino Nano & Relay

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine serving a perfectly cooked steak with edge-to-edge pink – without a $500 immersion circulator. With this kit, you’ll build your own sous-vide precision cooker: a waterproof DS18B20 sensor reads water temperature in real time, while an Arduino Nano drives a heater relay to hold the bath at exactly your target. A DS3231 real-time clock lets you schedule overnight cooks, and a servo even automates feeding for laboratory-style precision.

What You'll Build

A complete sous-vide cooking controller that maintains water temperature within ±0.5°C. Control a 12V DC heater (or any resistive load) via a relay, and set a second relay to turn on an indicator light when the cycle completes. The servo mechanism drops food pellets at pre-programmed intervals, so you can set up a slow cook in the morning and return to a ready meal.

What You'll Learn

• Calibrate and read a waterproof DS18B20 digital temperature sensor with Arduino.
• Use a DS3231 RTC module to schedule relay actions at precise times.
• Control high-power devices safely using a 5V relay module (heater and indicator).
• Program a servo motor to automate a feeding mechanism based on time or temperature.
