Abstract
The invention relates to a Sensor (10) for controlling an automatic door, where the sensor (10) comprises a laser scanner (12) for detecting the presence of an object, with at least one laser curtain (22, 32, 34) in a predefined detection area of the scanning field, where the sensor (10) comprises a distance data acquisition unit (13) that is embodied to acquire the distances of the points of reflection of the reflected signal by evaluation of time of flight, a presence detection unit (15), where the result of the distance data acquisition unit (13) is fed to the presence detection unit (15), where the distance data acquisition unit (13) forwards the distance data information to the presence detection unit (15), where the presence detection unit (15) evaluates, if an object is detected within the predefined detection area by analysing the distance data, where a presence detection information is created and fed to an at least one sensor output port (18, 18b). The invention is characterized in that the sensor further comprises an object information unit (11) comprising a human body identification unit (16), where the object information unit (11) receives the distance data, and the hu…
