The IoT Price Tag Update System is an AI + IoT project that combines AI demand prediction and Low stock alerts, built with Raspberry Pi. The project follows a clean, modular pipeline where sensor data acquisition, AI processing, and presentation stay separated, making it easy to test, extend, and present. It showcases practical AI and IoT techniques while producing a working, demo-ready system.
Manual monitoring and decision making for this task is slow, inefficient, and cannot scale across many devices. Without an AI + IoT approach built on Low stock alerts and Raspberry Pi, users cannot collect data from the physical world and act on it intelligently in real time.
This project applies AI + IoT techniques through AI demand prediction, orchestrated with Raspberry Pi and Low stock alerts. The system is designed for reliability and intelligence, with sensing, connectivity, AI analysis, and clear evaluation. It produces consistent, reusable results and can be adapted to related smart applications with minimal changes.
