Abstract
An apparatus periodically dispenses an air freshening substance from a pressurized container into a room. A device is provided to sense when the room is occupied, such as by detecting the light level in the room. The air freshening substance is dispensed more frequently when the room is being used than at other times. However, the dispensing continues even when the room is unoccupied to treat odors arising from objects permanently located in the room.
