There is provided an automatic door sensor device () capable of preventing a door () which is transitioning from an open position to a closed position from being erroneously detected as an object by temporarily changing a detection area (A, C, C). The automatic door sensor device () includes a doorway area sensor () that detects the presence of an object in a doorway area (B) which includes at least a portion of an area defined by the path of a door (), detectors () that detect the presence and/or the movement of an object in changeable detection areas (A, C, C), and a detection area changer () that changes the detection areas (A, C, C) when it is determined, by using the doorway area sensor (), that the door () is transitioning from an open position to a closed position.

Automatic door sensor device

An automatic door sensor includes: at least one sensor module unit (sensor module) configured to detect optically an object or a human body and to output, according to the detection results, a signal to a door controller for controlling an automatic door to open/close; an accommodation unit (profile) capable of accommodating the at least one sensor module unit; a cover member (front cover) that is transmissive to light for use for the detection performed by the sensor module unit and configured to cover the accommodation unit in which the sensor module unit is accommodated; and a functionality expansion module (LED module) either side of which can be joined to the cover member and that is configured to expand functionalities of the automatic door sensor by performing communication with the sensor module unit.
