Provided is an area monitoring sensor capable of recording sensing information of an intruder that has triggered to output an operation disable signal, and displaying the information as needed. The area monitoring sensor includes: an intruder sensing unit that emits detection light in different emitting directions and senses an intruder within a previously set monitor area based on reflection of the detection light; a signal output unit that outputs an operation disable signal based on a result of the sensing by the intruder sensing unit; a sensing history recording unit that stores a position of the intruder that has been sensed by the intruder sensing unit as sensing history; and a sensing history display unit that displays the sensing history in the sensing history recording unit based on an input signal from the operation input unit. |
