Technology development delivers the Internet of Things (IoT) to control and monitor the digital system. Augmented Reality (AR) has the ability to display 3D virtual objects into real environments. In general, the interface on IoT monitoring uses a static computer screen, in a dashboard model. This research focuses on integrating interfaces in the IoT monitoring system using augmented reality. Our work includes making the applications for mobile devices using EasyAR and building the connectivity to an online database. We also create the prototype of an IoT device to send data. We measured the system speed displaying the object with AR. Although the data stored online, we find out how effective this system is compared to its predecessor, which is using the static dashboard. We studied and measured the convenience of the use and the user experience.
