One aspect of the invention relates to a method of supplying power to a sensor arrangement including a first sensor and at least one second sensor which in each case have a first and a second supply terminal, and which can be operated in a first and a second operating mode. The first and at least one second sensor can be connected via their supply terminals to a voltage supply arrangement in the first operating mode. The first and at least one second sensor can be connected in series with one another via their supply terminals in the second operating mode and the series circuit with the first and at least one second sensor is connected in series with a current source.
