Arduino Mega Aquarium Controller Kit - Automate pH, EC & Lights
Automate Your Aquarium or Hydroponic System with Arduino Mega - Full Nutrient & Light Controller 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.
Take full command of your aquarium or hydroponic reservoir - automatically monitor and adjust electrical conductivity (EC), pH, water temperature, ambient light, and run precise pump cycles and grow light schedules. This kit lets you build a central nervous system for your plants or aquatic life, with real-time data on an OLED display and SD card logging. Whether you're managing a high-value reef tank or a commercial hydroponic setup, you'll eliminate manual testing and dosing forever.
What You'll Build
A fully functional aquarium/hydroponics controller with an OLED dashboard showing pH, EC, temperature, and light levels. The system automatically doses pH adjusters via relay-driven peristaltic pumps, runs a pump cycle timer, and switches grow lights with MOSFETs based on a DS3231 RTC schedule - all logged to microSD for analysis. You'll calibrate each sensor and tune a PID loop for stable nutrient conditions.
What You'll Learn
- Interface multiple I2C and one-wire sensors (pH, EC, light, temperature) with Arduino Mega
- Implement PID control algorithms to maintain stable nutrient solution conditions
- Use MOSFETs and relays to safely switch pumps and high-power lights
- Log sensor data to a microSD card and render real-time readings on an OLED screen

Who This Kit Is For
This advanced kit is ideal for B.Tech ECE/EEE students building final-year projects, IIT/NIT/VIT researchers prototyping smart agriculture systems, and serious hobbyists automating high-value aquariums or hydroponic setups. It's also suited for Smart India Hackathon participants tackling agricultural automation challenges and ATL mentors guiding advanced environmental control projects.
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?
Open the QR code for the AI companion chat - it knows every component and wiring detail. For human help, WhatsApp us directly; we respond within a few hours on working days.
Can I use this kit for a hydroponic nutrient dosing system?
Absolutely. The TDS EC meter and pH module, combined with relay-triggered peristaltic pumps, make it perfect for dosing pH up/down and nutrient solutions based on real-time readings. The PID algorithm can maintain precise EC and pH setpoints.
Does this kit control both aquarium lights and water pumps?
Yes, the DS3231 RTC schedules light on/off cycles via MOSFETs, while the 4-channel relay module can switch water pumps or aeration. You can program pump run times for circulation or feeding.
Is the AI companion helpful for debugging the PID control?
Yes, our AI build companion is trained on this exact project and can walk you through tuning PID constants, wiring the pH module, and addressing common sensor reading fluctuations - all accessible via QR code and WhatsApp backup.
Aquarium - Controls EC, pH dosing, pump cycle timer and grow light spectrum. Full PID control of nutrient solution.
