Web-Controlled Relay System for Lights, Pumps & Filters

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 switching on your aquarium lights, filter, aerator, and heater - all from a single browser page on your phone, with custom labels like 'Moonlight' and 'Feeder'. This kit guides you through building a four-channel relay controller using the ESP32's built-in WiFi, giving you remote control over your underwater ecosystem without any complex coding. Whether you're a student preparing a science exhibit or a hobbyist automating a fish tank, the result is a clean, real-time dashboard that makes IoT tangible.

What You'll Build

A compact, web-based relay board that lets you name each channel (e.g., 'Main Light', 'Air Pump', 'Heater', 'CO?') and toggle them on/off from any device on the same WiFi network. The interface shows real-time relay states, so you always know what's active. Build it once, and you'll have a reusable automation platform that will impress judges at a school science fair or make daily aquarium care effortless.

What You'll Learn

• Upload and modify web server code on the ESP32 using Arduino IDE
• Wire a 4-channel relay module safely with protection diodes and indicator LEDs
• Create a simple dashboard that updates relay states instantly via browser
• Understand the basics of HTTP requests, GPIO control, and electrical isolation
