Abstract
An overhead occupancy sensor assembly includes a housing, a lens disposed in the housing, a sensing element disposed behind the lens and configured to detect light, and a light blocking element, the light blocking element being configured to block light from reaching the sensing element. The light blocking element is a re-shapeable filter element or a rejection pattern of the lens. A continuous range of motion extension adapter may be included to allow optimal positioning of the sensor device for improved detection.
