I. Introduction
Room management means to put a room in order for optimum use. It also involves the maintenance of the room’s cleanliness. However, more than just maintaining its order, it also includes monitoring of the room’s electrical components such as lights and fans.
As we approach the age where automation becomes fashion and everything seems to be automatic, systems for lighting controls are created.
A lighting control system consists of a
