A sensor device for transmitting a sensor parameterization between sensors. The sensor device includes a first sensor with a sensor parameterization and a second sensor. The first sensor and the second sensor communicate with each other via a communication link. The first sensor sends the sensor parameterization to the second sensor via the communication link. The second sensor receives and accepts the sensor parameterization. The second sensor further provides the first sensor with the energy required to transmit the sensor parameterization via the communication link.
