Inspired by IoT-driven solutions like Ikasa and Retbella, this system enhances user convenience through real-time tracking, efficient management, and user-friendly mobile applications. The system architecture incorporates the NEO-6 GPS module for precise location tracking, ESP32 microcontrollers for seamless integration with reed switches, and Firebase for real-time data updates and secure management. Developed using React Native, the app offers cross-platform compatibility and QR code functionality for streamlined user interactions. Results demonstrate the system's ability to optimize umbrella management and rental processes, contributing to operational efficiency and environmental sustainability. Future directions include integrating advanced sensor technology and AI to elevate user adaptability and real-time monitoring." }
