IoT-Based Integrated Parking System Prototype using RFID and HC-SR04

Most parking system solutions developed to serve a significant number of cars, e.g., office buildings in Indonesia, do not include a feature directing the drivers to the location of available parking space that can be helpful for them. Several studies have been done regarding smart-parking systems. However, none provides integrated solutions, including membership payment, parking log, and available parking slots feature that can direct drivers to an empty parking slot. This study aims to propose an IoT-based parking system integrating the mentioned features. Radio Frequency Identification (RFID) and HC-SR04 sensors are utilized to record all cars entering parking areas and monitor them to generate empty parking slot information. The proposed system is applicable, and its functionalities work according to the system design.
