Abstract

A sensor array and a method are provided for operating a sensor array with a first sensor and a second sensor, the second sensor being designed for an operation at an ambient temperature, the first sensor representing a heated sensor, which is designed for being operated at an operating temperature that is above the ambient temperature, the first and the second sensor being connected to each other via a carrier, the carrier bringing about thermal coupling between the first and the second sensor, the first sensor being heated to the operating temperature during a first phase, and a measurement being carried out by the first sensor during the first phase, the heating being switched off or at least being reduced in a second phase, and a measurement being carried out by the second sensor during the second phase, an increased temperature of the second sensor as a result of the heating during the first phase being taken into account when evaluating the measurement of the second sensor.
