Abstract
Apparatus and methods for detecting presence and motion by an electronic device are disclosed. In an example device, the device includes a housing defining an opening, an infrared (“IR”) sensor located within the housing and generating an indication signal when the IR sensor detects an IR signal. The example device may further include a mirror disposed within the housing and having an unobstructed path and line of sight to outside of the electronic device via the opening and oriented to direct the first IR signal towards the IR sensor.
