From the project

A wire-free laser security tripwire system powered by an ESP32-S3. Features independent transmitter nodes, multi-bounce mirror pathing, dynamic auto-ambient light calibration, custom KiCad PCB files, and 3D mechanical mounts.

A professional, budget-friendly embedded security system built around a custom PCB and the ESP32 DevKit V1. This project utilizes an optical multi-bounce laser path bounced across real glass mirrors to form a tight perimeter grid, monitored dynamically by an onboard Light Dependent Resistor (LDR).

Wireless Perimeter Design: The laser operates on its own isolated battery across the room, eliminating long, messy signal lines back to the controller. Multi-Bounce Path: Supports $650\text{nm}$ red or $532\text{nm}$ green lasers, holding a sharp focal point through 4 to 5 mirror reflections. Auto…
