Build a WiFi Window Security Alarm & Garage Door Controller with ESP8266

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Turn a simple window opening into an instant alert and remotely control a garage door — all from your phone’s browser. This kit combines a magnetic reed switch sensor with an ESP8266-powered web interface and relay, giving you a practical IoT security system. Whether you’re prototyping a smart home project or building a functional workshop entrance controller, you’ll have a fully working system in one afternoon.

What You'll Build

A dual-purpose security node that mounts on any window or door. When the reed switch separates, the red LED lights up on the circuit and the web dashboard shows “Window Open.” A second reed switch confirms your garage door’s actual state. A button on the same web page triggers a 5V relay — isolating and protecting your existing garage door opener — so you never step outside again. Two green LEDs provide clear, at-a-glance status.

What You'll Learn

• Program the ESP8266 NodeMCU to run a web server with real-time GPIO monitoring
• Interface reed switches and read digital inputs accurately, even with door chattering
• Drive a 5V relay module safely, using the 1N4007 flyback diode to protect the microcontroller
• Wire a breadboard circuit with pull-down resistors, LEDs, and proper power distribution

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11–12 students tackling IoT in their computer science coursework, B.Tech ECE/EEE first-years building a mini-project for Smart India Hackathon, and ATL Tinkering Lab mentors who need a reliable, repeatable module for group workshops. It’s equally suited for self-learners at IIT, NIT, VIT, or BITS Pilani dorms who want a functional home-automation prototype on their desk.

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.
