Abstract
An electronic device for detecting presence includes a housing and an infrared (“IR”) sensor. The housing includes an outer surface having an opening formed thereon. The IR sensor is disposed in the housing and adjacent to the opening. The IR sensor has an unobstructed path and line of sight through the opening to outside of the housing. The IR sensor is configured to receive heat emitted by a person from outside of the housing via the opening and to generate a signal in response thereto.
