Based on the combination of Bluetooth and RFID to achieve campus shared umbrellas

Bluetooth and RFID technologies have various applications. Bluetooth is commonly used for wireless communication between devices over short distances. It enables the transfer of data and information, making it suitable for applications such as wireless audio streaming, file sharing, and device connectivity.

On the other hand, RFID (Radio Frequency Identification) is a system that uses electromagnetic fields to automatically identify and track objects. It consists of tags or labels attached to objects and readers or scanners that detect and read the information on those tags. RFID technology finds applications in inventory management, access control systems, supply chain management, and contactless payment systems.

Both Bluetooth and RFID technologies play important roles in enabling wireless connectivity, data transfer, and automated identification and tracking. They have revolutionized industries and have become integral parts of various systems and devices in our daily lives.

In response to the unexpected rainstorms that occur in certain campus public places, a cutting-edge campus umbrella system has been developed based on Bluetooth technology. This innovative system aims to provide self-service umbrella borrowing and returning services within designated areas. Leveraging STM32 real-time processing as a crucial technical component, the system incorporates Bluetooth modules and RFID radio frequency identification technology, along with hardware such as solenoid valves and relays, to ensure efficient real-time processing and billing.

To access the umbrella borrowing service, users can simply scan the QR code on the umbrella stand using WeChat. This action enables their mobile phones to receive information regarding umbrella sharing, including fee collection and other related activities. The incorporation of Bluetooth and RFID technology ensures seamless communication between users' mobile devices, the umbrella stand, and the system's billing system.

Through rigorous testing, the campus umbrella system has demonstrated straightforward operation and low implementation costs, making it an economically viable solution for providing sharing services. Users can conveniently borrow and return umbrellas as needed, without the need for manual supervision or physical payment transactions. This not only saves time and effort for both the users and administrators but also encourages a culture of resource sharing and environmental sustainability on campus.

With the Bluetooth-based campus umbrella system in place, students and faculty members can confidently navigate their way through sudden rainstorms, knowing that umbrellas are readily available for their temporary use. This not only enhances convenience but also contributes to a more pleasant and harmonious campus experience.

In conclusion, the campus umbrella system, powered by Bluetooth technology, offers a practical solution to address the challenges presented by unpredictable weather conditions. By embracing this system, universities and educational institutions can promote resource sharing, streamline operations, and enhance the overall well-being of their campus community.
