Abstract
A sensor device comprises a sensor unit for generating a signal indicative of a physical quantity. The device comprises a processing unit for receiving the signal, in which the processing unit comprises a storage memory for storing data derived from the signal as provided by the sensor unit at at least two points in time. The device comprises a bus interface for communicating with an electronic control unit via a digital communication bus. When a read command is received from the electronic control unit, an estimate of the physical quantity is sent in response to the electronic control unit. The processing unit comprises an estimator for calculating the estimate at a reference point in time based on the data stored in the storage memory, in which the reference point in time differs from the point in time at which the read command is received by substantially a predetermined offset.
