Abstract
A side looking occupancy sensor is incorporated in a conventional wall switch mounted into a switch box adjacent to a door. The side-looking proximity sensor preferably is mountable to either side of the doorjamb to make the side-looking proximity sensor face the door opening. During operation, the side-looking sensor monitors the door movement or senses the passage of a person for indication that a person is entering or leaving the space. Entry and exit determination is made based on activation of the side-looking sensor.
