This study focused on resolving issues arising from a smart notification system developed to enhance the convenience and stability of a sweet potato shoot attachment machine. We identified issues arising from the existing system’s sensing and notification methods and applied new sensing and improved notification methods to the improved system. And the improved system developed in this way was tested and its performance was compared and analyzed. Through this, we confirmed that the improved system outperforms the existing system in terms of performance. This paper proposes a development and verification method for an improved smart multi-functional notification system.
