Beschreibung
Zusammenfassung:	An electronic device (1) for measuring an ambient temperature (T air ) of the environment (51) of an electronic device is described. It comprises at least one integrated infrared sensor (2), a blinded window (20) preventing infrared radiation to directly impinge on the integrated infrared sensor and being in thermal contact with the environment as well as with a cover (50) of the device resulting in the blinded window (20) being at a surface temperature (T surface ). The at least one integrated infrared sensor is adapted for sensing the temperature of the blinded window (T surface ). The device also comprises at least one absolute temperature sensor for measuring a temperature of the at least one infrared sensor (T sensor ) itself, and a processing means for determining a temperature difference (T) between the sensed surface temperature (T surface ) and the temperature of the infrared sensor (T sensor ) and for calculating based thereon the ambient temperature (T air ).
