Automated Hydroponic NFT Controller Variant 4 Kit with Arduino Mega + Relay
Master Your Hydroponic Crop with an Automated NFT Controller Using Arduino Mega & Full PID
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Take full command of your recirculating hydroponic system. This kit lets you build an industrial-grade controller that continuously measures EC, pH, water temperature, and ambient light, then precisely doses nutrients and acid/base using peristaltic pumps, cycles submersible pumps on a schedule, and modulates grow light intensity—all governed by advanced PID algorithms for tight setpoint regulation.
What You'll Build
A wall-mountable unit that monitors every critical parameter in a hydroponic NFT channel. The 0.96-inch OLED displays real-time EC, pH, and system status. An SD card logs data with timestamps, while four relays and three MOSFET dimmers automate up to four pumps and three lighting zones. You’ll assemble it on a custom PCB prototype board, housed in a durable enclosure of your choice.
What You'll Learn
- Implement full PID control loops in Arduino code for nutrient dosing and pH balancing
- Interface industrial-grade sensors: TDS/EC meter, analog pH module, DS18B20 waterproof temperature probes, and BH1750 light sensor
- Drive peristaltic and centrifugal pumps through a relay module with RTC-based timing
- Build an expandable, soldered prototype board that can control a commercial-scale NFT operation

Who This Kit Is For
Agricultural engineers, commercial hydroponic growers, and research scholars at IIT, NIT, or ICAR who need a customizable, production-grade automation platform. It’s equally suited for final‑year B.Tech ECE/EEE students building precision agriculture projects for Smart India Hackathon, and for ATL mentors guiding advanced tinkering labs. If you already understand sensor calibration and basic Arduino programming, this kit pushes you into real‑world closed‑loop control.
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?
The AI companion will guide you through wiring, calibration, and code upload. For additional help, our Bengaluru support team is available on WhatsApp.
Can this controller handle a commercial-scale NFT system?
Yes, the four relays can switch pumps up to 10A each, and the three MOSFET channels can dim 12V grow lights up to 5A per channel—enough for multi-zone commercial setups.
Do I need to calibrate the pH and EC sensors before use?
Absolutely. The build guide includes steps to calibrate the pH module with buffer solutions and the EC meter with standard solutions; the AI companion walks you through the process.
Is the provided code open-source and modifiable?
Yes, the Arduino sketch is open-source and fully commented, so you can adjust PID parameters, pump timings, and logging intervals to match your crop’s specific needs.
Controls EC, pH dosing, pump cycle timer and grow light spectrum. Full PID control of nutrient solution.
