Aquarium Auto Controller Pro Kit with ESP32 + Sensor
Build an Automatic Aquarium Shutoff System with ESP32 & Wireless Sensor Network
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit hands you the complete design for an aquarium flood prevention system — eight water sensors spread around the tank and plumbing, all reporting back to a central ESP32 hub that instantly cuts off the water supply the moment any sensor detects a leak. The result is a project that solves a real, messy problem while teaching professional-grade wireless networking, power management, and relay control. For B.Tech ECE/EEE students, Smart India Hackathon teams, or any maker who wants a project with genuine utility, everything is in one box.
What You'll Build
You assemble a wireless mesh of eight Arduino Nano‑based sensor nodes, each powered by an 18650 cell and TP4056 charge module, communicating via NRF24L01 transceivers. The ESP32 hub logs every transmission and drives a 5V relay that opens or closes a solenoid valve. The moment any water sensor triggers, the relay de‑energises the valve within milliseconds, stopping the inflow before a drop spills. A local web dashboard served by the ESP32 lets you view real‑time sensor status and alert history from any phone or laptop on the same network.
What You'll Learn
- Design and deploy a multi‑node wireless sensor network using NRF24L01 modules
- Program Arduino Nano for low‑power sensor reading and radio transmission
- Set up an ESP32 as a hub that acts as web server, data logger and relay driver
- Build safe lithium‑ion battery circuits with TP4056 charging and protection
- Fabricate custom nodes on prototype PCBs and hone professional soldering skills

Who This Kit Is For
Designed for final‑year B.Tech ECE and EEE students hunting for a polished, documentation‑rich capstone project, as well as Smart India Hackathon teams tackling water‑conservation challenges. The multi‑node wireless architecture also suits hobbyists and tinkerers from IITs, NITs, VIT, BITS Pilani and ATL mentors who want to demonstrate a real IoT‑driven smart home solution.
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?
Your kit includes an AI companion that walks you through each connection and code block; if you need human help, our WhatsApp support team shares the same documentation and can resolve issues quickly.
Can I expand the system to monitor multiple aquariums?
Absolutely. The NRF24L01 network architecture supports up to 32 nodes, so you can add extra sensor‑node pairs to cover additional tanks without changing the hub code.
Do I need prior experience with wireless communication?
No — the AI companion explains the NRF24L01 library and packet structure in plain terms, and the provided Arduino sketches are fully commented for clarity.
How does the solenoid valve connect to the relay?
The 5V relay module switches an external 12V supply to the solenoid valve; detailed wiring diagrams and safety notes are included in the AI guide to prevent back‑EMF damage.
Aquarium Automation — Eight water sensors via ESP-NOW report to hub. Hub triggers solenoid valve shutoff on any detection.
