1. A method for determining a sensor value of a sensor, the method comprising the steps:
- supplying a first electrical supply voltage to the sensor,detecting a first electrical resistance of the sensor when being supplied with the first electrical supply voltage,supplying a second electrical supply voltage to the sensor, the second electrical supply voltage being different from the first electrical supply voltage,detecting a second electrical resistance of the sensor when being supplied with the second electrical supply voltage, andautomatically determining the sensor value depending on the first electrical supply voltage, the second electrical supply voltage, the first electrical resistance, and the second electrical resistance.

Abstract
For determining a sensor value of a sensor (13), a first electrical supply voltage (VS1) is supplied to the sensor (13) and a first electrical resistance of the sensor (13) is detected. Then, a second electrical supply voltage (VS2) is supplied to the sensor and a second electrical resistance of the sensor (13) is detected. The second electrical supply voltage (VS2) is different from the first electrical supply voltage (VS1). The sensor value is automatically determined depending on the first electrical supply voltage (VS1), the second electrical supply voltage (VS2), the first electrical resistance, and the second electrical resistance.
