Sensor device

A sensor device comprising:

• a plurality of sensors, each of which includes
• a sensor element configured to detect a change in a physical quantity, and
• a sensor-side communication circuit configured to transmit a signal having a response signal according to a detected value of the sensor element in response to a request signal, the response signal being transmitted in response to the request signal on a one-to-one basis;
• a controller including
• a controller-side communication circuit configured to transmit the request signal and receive the response signal, and
• an arithmetic processing unit configured to calculate detection data according to the response signal;
• and
• a plurality of communication paths connecting the plurality of sensors to the controller, respectively,
• wherein the arithmetic processing unit is further configured to calculate the detection data by adopting response signals acquired in parallel from the plurality of sensors,
• wherein:
• the sensor element in each of the plurality of sensors includes a plurality of sensor elements, and number of the plurality of sensor elements is k being an integer greater than or equal to 2;
• and
• the plurality of sensors transmits the response signals being signals according to respective detected values of a first sensor element to a kth sensor element included in the sensor element in a predetermined sequential order, and
• wherein:
• in-sensor detection data is data calculated by adopting the response signal including a (k−1)th nearest preceding response signal up to a present response signal generated in an identical one of the plurality of sensors;
• and
• the arithmetic processing unit is further configured to calculate the detection data by adopting a present value of the in-sensor detection data according to each of the plurality of sensors.
