Home Brewing Temperature Monitor Kit with Arduino Uno + Relay
Build an Automated Brewing pH & Temperature Controller with This Arduino Uno 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.
Once assembled, this kit becomes a guardian for your home brewery—constantly checking the pH and temperature of your fermenting beer, wine, or kombucha. If the brew gets too cold, the relay switches on a heater; if pH drifts too high, it can trigger a dosing pump. It’s a perfect blend of electronics and microbiology, giving you barista-level consistency with hands-off control.
What You'll Build
You’ll build a working pH and temperature monitoring station with LCD display. The system displays real-time readings and can automatically control two external devices—a heating pad and a pH correction pump—based on thresholds you set in the Arduino code. The result is a fermentation assistant that runs right on your kitchen counter, logging what matters while you sleep.
What You'll Learn
- Interfacing analog and digital sensors (pH module and DS18B20) with Arduino
- Programming conditional relay control for process automation
- Calibrating a pH sensor and converting analog readings to pH values
- Reading and displaying sensor data on a 16x2 LCD via I2C

Who This Kit Is For
CBSE Class 11-12 students working on interdisciplinary biology and electronics projects, B.Tech ECE/EEE students prototyping industrial automation concepts, and home brewing hobbyists across India looking to build a reliable fermentation monitor. It also suits Smart India Hackathon teams tackling agritech or food processing challenges.
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 on the box to talk to our AI companion trained on this kit. If you need human help, message us on WhatsApp; we’ll guide you through.
Do I need to buy the heater or dosing pump separately?
Yes, the kit includes the controller only. Any small 5V heater pad or peristaltic dosing pump that operates within the relay’s rating will connect nicely.
Is the pH sensor pre-calibrated?
The analog pH module requires a quick calibration using buffer solutions (not included). The AI companion walks you through the entire calibration process step by step.
Can I use this for fermenting traditional Indian drinks like rice beer or kanji?
Absolutely. The kit monitors any liquid fermentation where temperature and pH matter, from kanji and rice beer to yogurt or vinegar.
Brewing — pH sensor and DS18B20 water temp both monitored. Relay triggers heater or pH dosing pump when out of range.
