Auto Light Energy Saver Kit v5 — ESP32 PIR & Reed Switch System with MQTT Security Alerts

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

Stop wasting electricity in empty rooms and get a smarter way to know when something unusual happens. This kit combines automatic light control with a machine-learning–inspired sequence classifier on an ESP32. You'll build a system that learns your daily movement flow — using PIR motion and two door reed switches — then raises an MQTT security alert when an intrusion pattern is detected.

What You'll Build

A wall-mount prototype that detects room occupancy via infrared motion and magnetic door contacts. It uses the ESP32 to decide whether a series of door openings and motion events matches your regular pattern or an unexpected sequence. When an anomaly is flagged, the buzzer sounds and a message is published via MQTT. The device also switches off lights when no one is in the room, directly cutting energy waste.

What You'll Learn

• Wiring and reading a PIR motion sensor and magnetic reed switches on ESP32 GPIO pins
• Programming event-sequence analysis to distinguish routine entries from forced or tailgating intrusions
• Setting up Wi-Fi and MQTT client on ESP32 to push real-time security alerts
• Integrating hardware with logical rules for energy-saving automation

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11–12 students looking for a practical IoT project that merges energy conservation with security. B.Tech ECE/EEE undergraduates can use it for lab mini-projects on embedded systems or MQTT communication. ATL tinkering lab mentors will find it a ready-made platform to teach sensor fusion and event-driven logic. Smart India Hackathon participants can extend it into a full building automation prototype.

Built and Backed by Compoden
