<![CDATA[The development of Internet of Things (IoT) technology has encouraged the implementation of automated systems in various fields, including vehicle access management. Manual gate systems still have several limitations, such as dependence on operators, relatively slow response times, and the potential for human error. This study aims to design and develop an IoT-based automatic gate system using an Arduino Uno as the main controller and an ultrasonic sensor for object detection. The research employed an experimental method consisting of hardware design, software design, and system testing. The results show that the system can accurately detect the presence of vehicles within a specified distance and automatically control the gate barrier using a servo motor. In addition, the integration of components such as an LCD, LED, and buzzer provides users with clear information about the system status. Therefore, the developed system has demonstrated its ability to improve efficiency, security, and reliability compared with conventional manual gate systems.]]>
