ABSTRACT:
A human body sensing device capable of sensing not only the presence of the human body, but, also the human body's position. The device includes a lens unit, for dividing a room to be monitored into a plurality of lateral and vertical zones and projecting an infrared ray emitted from an object present in one of the zones, a filter unit, for filtering only an infrared ray emitted from the human body from infrared rays received from the lens unit, and an infrared sensor unit for sensing the human body's position, based on the infrared ray received from the filter unit.
