Abstract: The invention refers to a sensor (10) for presence detection, and a method for presence detection, in a detection area (18) comprising at least an image generator (14) for generating an image on a detection area (18) formed by illuminated structures reflecting from said detection area (18), a detector (20) for detecting signals of the image reflected from the detection area (18), an image processing unit (24) for comparing the signals based on the reflected and received image with signals of a reference image stored in storing means of the image processing unit (24), wherein the image generator (14) generates a pattern (16) on the detection area (18) having illuminated and non-illuminated zones, the image processing unit (24) uses triangulation technique to detect changes of the pattern (16) within the detection area (18) over the reference image.
