Aquarium Auto Controller Kit
Aquarium Auto Controller Kit: Automate Your Tank with AI Object Detection (Arduino & STM32)
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a fish tank that knows when your fish gather for food and dispenses exactly the right portion – without a smartphone, without the cloud. This kit lets you build a standalone AI controller that recognizes objects right on the Arduino UNO Q's camera feed, then commands an STM32 to flip a relay. Whether you want to automate feeding, activate a pump, or log fish activity, the system runs entirely on-device for instant, privacy-first responses.
What You'll Build
You'll assemble a camera-driven automation brain: the Arduino captures images via the OV2640 module, runs a pre-trained object detection model, and transmits the detected class name to the STM32 over serial. The STM32 interprets that command and energises the 5V relay to switch your appliance – a feeder, solenoid valve, or light. The OLED displays real-time detections and relay status, creating a compact, all-in-one gadget that mounts next to your tank.
What You'll Learn
- Deploy a TensorFlow Lite object detection model on an Arduino microcontroller with limited RAM
- Interface an OV2640 camera module and capture frames for inference
- Set up UART communication between Arduino and STM32 to relay AI decisions
- Design a relay driver circuit with 1N4007 flyback diodes and 100nF decoupling capacitors

Who This Kit Is For
This kit is built for engineering students (B.Tech ECE/EEE, CS with IoT interest) tackling major projects or hackathons like Smart India Hackathon. It fits perfectly into final-year projects at IITs, NITs, VIT, and BITS Pilani where edge AI and industrial automation are graded. Advanced CBSE Class 11‑12 students at ATL Tinkering Labs with prior Arduino experience will also find it a rewarding intermediate challenge.
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 to start the AI companion, which walks you through each step. You can also message us on WhatsApp for human support.
Do I need prior experience with AI or STM32?
Basic Arduino IDE familiarity helps. The companion explains model architecture, provides pre-configured code, and breaks down UART communication so you can learn as you go.
Can I retrain the detection model for my own fish species?
Yes, the companion includes a retraining guide. You can capture images of your tank inhabitants, annotate them, and generate a custom model that runs on the same hardware.
Is soldering required?
Yes, the kit includes a soldering iron and solder wire. You'll mount the diodes, resistors, and capacitors on the PCB prototype board to build the relay interface. The companion shows you exactly what to do.
Aquarium Automation — Arduino App Lab runs a pre-trained object detection model on the MPU. Detected class name triggers STM32 GPIO relay.
