Abstract

The rapid advancement of the Internet of Things (IoT) has enabled the development of smart systems that automate various aspects of urban infrastructure, including parking management. This study aims to design and implement an IoT-based parking lot monitoring system that assists drivers in identifying available parking spaces and locating them accurately within a parking area. The system provides real-time information regarding slot availability through a display installed at the entrance gate. The prototype employs an ESP32 microcontroller, ultrasonic sensors, a PIR (Passive Infrared) sensor, a servo motor, LED indicators, and a buzzer as the main hardware components. The system software was developed using the Arduino IDE for embedded programming and Microsoft Visual Studio (C#) for the desktop monitoring application. System testing demonstrates that the prototype successfully delivers real-time information on parking slot occupancy and overall parking capacity. The proposed system enhances the effectiveness and efficiency of parking management for both operators and users.

Abstract

Academic time management is a crucial aspect in maintaining discipline and order in school learning activities. However, school bell systems that are still operated manually are prone to delays and operational errors due to human factors. This study aims to implement Internet of Things (IoT) technology to support the Smart School concept through the development of an automatic school bell system. The research employed a system engineering approach using a case study method with the Waterfall development model, which consists of the stages of requirements analysis, system design, implementation, testing, and maintenance. The system was developed using an ESP32 microcontroller as the main controller, time synchronization based on the Network Time Protocol (NTP), and a DFPlayer Mini module with speakers as audio output devices. System testing was conducted using the black box testing method to evaluate the main system functionalities, as well as user acceptance testing (UAT) involving 10 respondents consisting of teachers and school staff to assess system usability and performance. The testing results indicate that the system is able to activate the school bell automatically according to the predefined schedule with a 100% success rate across all test scenarios. In addition, the system is equipped with a web-based interface that facilitates the management of bell schedules and active school days. The implementation of this system has proven to improve time accuracy and operational efficiency in academic activity management, thereby supporting the practical application of the Smart School concept.
