INTRUSION SENSOR

摘要

An intrusion sensor includes: a microwave sensor (110) for transmitting a microwave toward a detection area and receiving a reflected wave of the microwave from an object existing in the detection area, so as to output distance information corresponding to a distance to the object and output perpendicular angle information corresponding to the direction of the object; detection object existence judgment means (120) for judging that a detection object exists in the detection area when the distance information is within a predetermined distance range decided according to the perpendicular angle information and height information on the set position; and alarm signal output control means (130) for outputting an alarm signal when the detection object existence judgment means has judged that a detection objection exists.
