Abstract
A sensor device has at least one first sensor element for detecting a touch and/or an approach, which is configured as a capacitive sensor element and which has a first electrode structure with a transmitting electrode and a reception electrode, wherein a first alternating electrical field emitted by the transmitting electrode may be coupled into the reception electrode,—at least one second sensor element, and—an evaluating device, which is coupled with the at least one first sensor element and with the at least one second sensor element, wherein the evaluating device is configured to evaluate a first signal tapped from the reception electrode of the first sensor element and at least one second signal provided by the second sensor element and to generate at least one detection signal dependent on the evaluation.
