Abstract: An ultraviolet (UV) light germicidal sanitizing system for use in an enclosed space comprises a room occupancy sensor, a door sensor, a UV light generating unit, and a control software application. The room occupancy sensor is positioned in the enclosed space and generates a first signal indicating that the enclosed space is either occupied or unoccupied. The room occupancy sensor is implemented with a door providing access to the enclosed space and generates a second signal indicating that the door is either open or closed. The UV light generating unit receives the first and second signals and generates UV light into the enclosed space if the first signal indicates that the enclosed space is unoccupied and the second signal indicates that the door is closed. The control software application generates commands for the UV light generating unit to start generating UV light and to stop generating UV light.
