Vertical Hydroponic Tower Controller Kit with Arduino Uno + Relay
Build a Vertical Hydroponic Tower Controller with Arduino Uno & Real-Time Pump Automation
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Construct a working controller that runs a peristaltic pump on precise timed cycles to deliver nutrient solution to a 6-pocket vertical tower. This kit logs EC (electrical conductivity) readings using an RTC, so you can track nutrient strength over time — a complete prototype for modern smart farming and agri-tech experiments.
What You'll Build
You'll assemble and program an Arduino Uno to control two relays that switch the pump and optionally a fan or lights. The DS3231 real-time clock schedules multiple feeding windows per day, while the TDS EC meter measures nutrient concentration and displays it on the 16x2 LCD. When finished, you'll have a reliable automated irrigator that can be adapted to any vertical tower setup.
What You'll Learn
- Programming timed events with the DS3231 RTC module
- Interfacing analog EC sensor with Arduino for nutrient monitoring
- Driving a peristaltic pump via relay with flyback diode protection
- Displaying sensor readings on an LCD with I2C backpack integration

Who This Kit Is For
Students in CBSE classes 11–12 exploring agricultural automation for science exhibitions; B.Tech. ECE/EEE students working on IoT-based smart farming projects; ATL Tinkering Lab coordinators looking for a structured hydroponics module; and participants of Smart India Hackathon or similar events. If you're passionate about sustainable farming and electronics, this kit gives you a hands-on head start.
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 chat with our AI build companion, which knows every pin connection and code line for this exact kit. You can also reach us via WhatsApp for human backup within 24 hours.
Can this controller run a real 6-pocket vertical tower?
Yes, the included mini peristaltic pump can lift nutrient solution up to 1 metre, which is typical for desktop towers. For larger towers, you can easily swap in a higher-flow pump using the same relay circuit.
How do I view and analyze the logged EC data?
The EC values are timestamped via the DS3231 RTC and can be sent to your computer through the Arduino's serial monitor. You can copy the data into a spreadsheet for tracking nutrient trends. An SD card module (not included) can be added to log data offline.
Can I modify the pump schedule after building?
Absolutely. The Arduino sketch is open and well-commented. You can change the feeding duration, interval, and number of cycles directly in the code to match specific crops like lettuce, basil, or strawberries.
