Abstract
Desktop computers are well known for their high flexibility and are widely used for advanced computing tasks such as software development, graphic design, and other resource-intensive applications. However, they remain limited in portability due to their relatively large physical size. To overcome this, desktop computers can be accessed remotely over the Internet using software such as Moonlight and Parsec. Nevertheless, this approach introduces another issue, as the computer must remain powered even when not in use, resulting in unnecessary energy consumption. This study aims to develop an Internet of Things (IoT)-based system capable of remotely controlling the power state of a desktop computer, turning it on and off as needed. The research adopts a systems engineering approach using the prototyping method, carried out iteratively from requirements analysis to testing and evaluation. The system utilizes an ESP32, Firebase Realtime Database, and a Flutter mobile app as the user interface. The results demonstrate reliable inter-device communication and remote computer power control with total average response time of approximately 50ms. The device has a compact form factor and is self-powered using the computer's 5V standby power supply. The Flutter mobile app exhibits a responsive user interface, with a render raster time of approximately 2ms on a 60 fps refresh rate. The developed system successfully enables remote computer power control, improving access flexibility while reducing unnecessary energy consumption, directly contributing to the advancement of science and technology, particularly in the application of IoT.
