Abstract
A sterilization device comprising an ultraviolet (UV) electromagnetic radiation (EMR) emitting device, a detector configured to detect occupancy of a room associated with the sterilization device, and a controller operably connected to each of the UV EMR emitting device and the detector. The detector is configured to send a signal indicating occupancy to the controller upon a detection of occupancy. The controller is configured to operate the UV EMR emitting device to emit UV EMR only upon receiving a signal indicating no occupancy.
