Abstract
Systems and methods of using active infrared (AIR) sensors to map a room of a home or building and determine whether an external portal (e.g., window and/or door) of the room is open or closed are provided. In particular, the systems and methods include outputting infrared (IR) light from an IR light source of an active infrared (AIR) sensor, receiving reflected IR light with a light sensor, and determining, with a processor coupled to the light sensor, whether a window of a room is open according to the received reflected IR light.
