An aircraft passenger service unit (2) for being installed in an overhead position in an aircraft passenger cabin (102) comprises an infrared sensor (30), which is configured for detecting infrared radiation and for providing a corresponding sensor output; and a controller (35), which is configured for receiving and evaluating the sensor output provided by the infrared sensor (30). The infrared sensor (30) is an infrared sensor array (30) configured for detecting infrared radiation emitted within a plurality of spatial sectors (34) covering a detection area (32) below the aircraft passenger service unit (2); and the infrared sensor array (30) is configured for detecting the infrared radiation individually for each spatial sector (34) and for providing individual sensor signals for the plurality of spatial sectors (34). The infrared sensor array (30) is configured such that each passenger seat (80a, 80b, 80c) arranged within the detection area (32) is covered by at least two of the plurality of spatial sectors (34), respectively; and the controller (35) is configured for determining a passenger seating position within a passenger seat (80a, 80b, 80c) from the individual sensor signals.
