The invention discloses a wireless sensor interface for a steering wheel. The object of the invention to overcome the problems according to the state-of-the art will be solved by a wireless sensor interface for a steering wheel with steering wheel components comprising on a transmitter side a wireless transmitter coil of a transmitter integrated circuit on a stationary printed circuit board; on a receiver side a wireless receiver coil of a receiver integrated circuit on a movable, rotating receiver printed circuit board, wherein the transmitter and receiver coils are mounted close to each other and concentric to a rotation axis of a steering column of the steering wheel, whereas an inductive coupling between the transmitter and receiver coils are used for wireless powering the steering wheel components and transmitting data of the steering wheel components back to the transmitter integrated circuit by means of modulating the received energy.
