SENSOR SUBASSEMBLY AND METHOD FOR SENDING A DATA SIGNAL
First Claim
1. A sensor device comprising:
- a memory circuit configured to store sensor data values of the sensor device, wherein each sensor data value represents a measured value of an oscillating quantity; and
a transmission circuit configured to send a first data signal to an external receiver in a first state of a read-out-mode of the sensor device, if an oscillation period of the oscillating quantity is longer than a period threshold, wherein the first data signal contains at least information on a current sensor data value representing a measured value of the oscillating quantity measured between a last preceding measured local maximum value of the oscillating quantity and a next succeeding local minimum value of the oscillating quantity,wherein the transmission circuit is configured to send a second data signal to the external receiver in a second state of the read-out-mode, if the oscillation period of the oscillating quantity is shorter than the period threshold, wherein the second data signal contains information on at least one of a first local extremum sensor data value and a succeeding second local extremum sensor data value.

Abstract
A sensor device includes a memory circuit and a transmission circuit. The transmission circuit sends a first data signal to an external receiver in a first state of a read-out-mode of the sensor device, if an oscillation period of the oscillating quantity is longer than a period threshold. Further, the transmission circuit sends a second data signal to the external receiver in a second state of the read-out-mode, if the oscillation period of the oscillating quantity is shorter than the period threshold. The second data signal contains information on at least one of a first local extremum sensor data value and a succeeding second local extremum sensor data value.
