<![CDATA[Parking capacity management requires information that can be obtained quickly and accurately because the number of vehicles in a campus parking area changes dynamically. This study aims to design and implement an Internet of Things (IoT)-based motorcycle parking capacity monitoring system at the parking area of Universitas Pamulang Serang Campus. The research used an experimental approach and a design-and-build method consisting of problem identification, literature study, system analysis, hardware and software design, implementation, functional testing, and result analysis. The system integrates an ESP32 microcontroller, RFID RC522, two HC-SR04 ultrasonic sensors, an MG996R servo motor, an I2C LCD, buzzer, Blynk IoT dashboard, and an Android smartphone with IP Webcam. RFID authenticates vehicle access, the ultrasonic sensors detect entry and exit sequences, the servo controls the barrier gate, while the LCD and Blynk display the number of vehicles and remaining parking capacity in real time. Functional testing showed that the RFID, ultrasonic sensors, servo motor, LCD, buzzer, Blynk dashboard, data persistence, vehicle entry and exit processes, and visual monitoring operated according to the design. The system also rejects vehicle entry when the maximum capacity of five motorcycles is reached. The implementation demonstrates that an integrated IoT system can support structured parking capacity monitoring and access management in a campus environment.]]>
