An IoT-based smart parking management system

In this paper, the author implemented smart parking information management system based on IoT using ultrasonic parking sensor and Bluetooth beacon. Ultrasonic IoT sensors used for parking sensing are controlled by the Arduino board to collect parking sensing data, and the collected parking information is transmitted to the server in real time using the MQTT protocol. The server stores the parking information in the database and provides the vehicle driver with real-time parking status using the MQTT protocol. The driver starts the smartphone app in the parking lot and enters the parking lot. The smartphone automatically recognises which parking space using the Bluetooth beacon signal at the entrance of the parking lot and can confirm the parking information of the parking space to be parked at a glance by communicating with the server. The parking management system implemented in this study not only helps the driver to park the car but also uses the real-time parking information stored in the database to obtain marketing information such as hourly, daily or monthly number of visiting customers and average shopping time.
