Abstract
Emission of a scented substance, which is mixed with a tracer substance, is controlled based on an amount of the tracer substance sensed during the emission of the scented substance. The scented substance can be mixed with the tracer substance in a known defined ratio. When the mixture of the scented substance and tracer substance is being emitted by a device, a substance sensor component can sense the amount of the tracer substance being emitted. An emission management component can control the emission of the mixture of substances based on the amount of the tracer substance detected to facilitate controlling the amount of the scented substance being emitted. The emission management component also can control emission of the scented substance in a defined area based on the tracer substance and environmental conditions in the defined area. The tracer substance can be safe, colorless, and/or odorless with respect to people.
