This research aims to design and build a mini prototype of an anti-theft security system for displaying goods using an ESP32 microcontroller, infrared (IR) sensor, buzzer module, and SG90 micro servo. The system is designed to detect lost items through IR sensors, trigger alarms through buzzers, automatically close doors using SG90 servos, and send notifications to Telegram via ESP32. The test results show that the system can function well and be responsive in detecting theft, providing voice alerts, closing doors, and sending real-time notifications.
