Automated Aquarium Dosing System Kit with Arduino Mega + Relay
Automated Aquarium Dosing System with Arduino Mega: Precise Fertiliser & Nutrient Control
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform your planted aquarium or reef tank into an autonomous ecosystem. This kit lets you build a fully programmable dosing system that dispenses liquid fertilisers, trace elements, carbon supplements, and pH buffers at exact times set by a DS3231 real-time clock—no more manual daily dosing or nutrient swings.
What You'll Build
You’ll assemble and code a multi-pump dosing station that activates four peristaltic pumps on a customisable weekly schedule. The onboard microSD card logs every dose for analysis, while the OLED display and tactile buttons let you navigate menus and adjust timing without a PC. The result is a professional-grade dosing solution that maintains water parameters with scientific consistency, keeping plants vibrant or corals thriving.
What You'll Learn
- Interfacing peristaltic pump motors and relay control with Arduino Mega GPIO
- Programming a DS3231 real-time clock for precise, recurring dosing schedules
- Building a menu-driven user interface on a 0.96-inch OLED with tactile buttons
- Implementing data logging to microSD for dosage tracking and system diagnostics

Who This Kit Is For
B.Tech ECE/EEE students working on automation or IoT-centric final-year projects, or Smart India Hackathon teams prototyping automated hydroponics/aquaponics solutions. Also ideal for aquarium enthusiasts across India who want to maintain precision water parameters in high-tech planted tanks or marine setups. Perfect for college-level makers at IITs, NITs, VIT, and BITS Pilani tackling smart home and precision agriculture 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?
Just scan the QR code inside the box to chat with your AI build companion, or send a WhatsApp message to our support team for real-time guidance — we respond within a few hours.
Can I calibrate different flow rates for each peristaltic pump?
Yes, the AI companion guides you through pump calibration, letting you set custom millilitre-per-second values for each channel so doses are accurate regardless of tube wear or liquid viscosity.
