Home Brewing Temperature Monitor Plus Kit with Arduino Uno + Relay
Ensure Perfect Fermentation with the Arduino Uno Home Brewing Temperature Monitor Kit
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 a smart device that holds your home-brewed kombucha, yogurt, or craft beer at the exact temperature needed for perfect fermentation — without constant monitoring. This kit turns an Arduino Uno into a full hysteresis thermostat, showing live readings on an LCD and clicking a relay on and off to keep your brew within a tight window. It’s your first step into smart home automation, built entirely by you.
What You'll Build
You’ll assemble a complete temperature control system on a breadboard. The DS18B20 waterproof probe reads the liquid temperature, the Arduino compares it to a user-set target, and the 5V relay toggles a heater (like a heat belt or bulb) to maintain the range. Two buttons let you raise or lower the target, while the 16x2 LCD shows current temp and setpoint in real time — the same logic used in commercial fermenters, miniaturized by your hands.
What You'll Learn
- Reading digital temperature sensors with the 1-Wire protocol and DallasTemperature library
- Implementing hysteresis in code to prevent relay chattering and ensure stable control
- Driving a 5V relay module safely to switch AC or DC heating loads
- Displaying real-time data on an I2C-backed 16x2 LCD without messy wiring

Who This Kit Is For
Perfect for middle-school STEM explorers, CBSE Class 11-12 physics and electronics students, ATL Tinkering Lab projects, and B.Tech ECE/EEE students prototyping IoT temperature systems. Also an engaging parent-child build for families exploring how smart thermostats work — no soldering needed, just plug into a breadboard.
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 open your AI companion, which walks you through every connection and code line. You can also share a photo on WhatsApp and get help from our support engineers the same day.
Can I really control a heating element for real brewing?
Yes — the relay can switch AC loads up to 10A, so you can control a small heat belt or bulb. Always use the diodes provided for flyback protection and follow the safety guidelines in the AI companion. This kit is a working prototype for low‑volume fermentation vessels.
Is any coding experience needed?
None. The AI companion provides the complete sketch, explaining each line. You’ll upload it via the Arduino IDE with a single click, and the code is heavily commented so you learn by doing.
Can I change the setpoint without reprogramming?
Absolutely — the two tactile buttons let you increment or decrement the target temperature on the fly. The LCD updates instantly, and the relay responds to keep your brew in range.
Brewing — DS18B20 controls relay heater to hold target temperature with hysteresis. LCD shows temps.
