ESP32 Aquarium Auto Shut-Off Kit with Wireless Water Sensors
Stop Aquarium Floods Before They Happen - ESP32 Wireless Water Leak Detection Kit with Automatic Shut-Off
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
An undetected water leak under a sink or near an aquarium can cause thousands in damage. This kit lets you build a six-node wireless sensor network that talks to a central ESP32 hub - if any sensor detects water, the hub instantly triggers a relay to shut off the main water supply, preventing flooding before you even notice it.
What You'll Build
A fully functional wireless water leak detection and shut-off system. Position six water sensors at potential leak points - under sinks, near the aquarium, behind appliances. When moisture is detected, the ESP32 hub receives the alert and activates a 5V relay module, cutting power to a solenoid valve (not included) that stops water flow. A practical, real-world automation project for serious DIYers.
What You'll Learn
- Designing multi-node wireless sensor networks with NRF24L01 modules
- Programming Arduino Nano for low-power water sensor monitoring
- Configuring the ESP32 as a central hub for data aggregation and relay logic
- Soldering and assembling prototype boards for rugged, deployable modules

Who This Kit Is For
This kit suits advanced hobbyists and engineering students tackling home automation projects - think B.Tech ECE/EEE final-year projects, Smart India Hackathon prototype builds, and ATL Tinkering Lab mentors. It's also perfect for aquarium enthusiasts who want to safeguard expensive setups with a custom, expandable leak detection system.
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?
Our AI companion can walk you through wiring and code, and our team is available on WhatsApp for extra guidance.
Can I add more than six sensors?
Yes, the NRF24L01 network can be scaled; the ESP32 firmware can easily accommodate additional node addresses with minor code changes.
Does the kit include a solenoid water valve?
The kit includes a 5V relay to control an external solenoid valve - we recommend a 12V DC valve which you can source separately based on your plumbing specifications.
What if I want to use this system to detect other liquids?
The water sensors detect conductivity, so they work with any conductive liquid. For non-aqueous setups, contact us for sensor alternatives.
