Implementation of Digital Signage Based on Embedded System and IoT Using Mac Address as an Identifier on Laboratory in-Out Announcer Board

The rapid development and utilization of information technology, mostly in the use of digital signage and Internet of Thing (IoT) have penetrated into all areas where the implementation has so many benefits and convenience. Hence, the implementation of IoT-based digital signage for in-out lecturer announcement board and staff is deemed important to be done, particularly in supporting the concept of smart laboratory applied in the Laboratory of Electronic Systems Department Electrical Engineering and Information Technology, Faculty of Engineering UGM. The implementation of IoT-based digital signage for in-out lecturers and staff members of the Electronic Systems Laboratory is developed by means of WEB-based interface, while for the identification of laboratory members existence it uses Raspberry P as an embedded system by utilizing user-owned device mac address connected to the laboratory Wi-Fi hotspot. The in-out status is always updated automatically according to the connectivity of laboratory member's devices with Wi-Fi hotspot.
