1. A sensor device for transmitting, to an external device installed external to the sensor device, sensing data generated from monitoring a target, the sensor device comprising:
a sensor unit configured to generate sensing data including background noise data, the background noise data representing noise from a cause other than the target;
an extraction unit configured to extract the background noise data from the sensing data by sorting the items of sensing data generated at a plurality of times into sorted arrays of element values based on values indicated by the items of sensing data, the background noise data comprising the sensing data in the sorted arrays whose sort order is equal to a predetermined order; and
a transmission unit configured to transmit the sensing data and configured to transmit the extracted background noise data to the external device separately from transmitting the sensing data, wherein
the background noise indicates a reliability of the sensor device;
the background noise is generated in response to a request,
the sorted arrays include same segments representing the background noise, and the sensing data for the sorted arrays includes different signal patterns, and
the reliability of the sensing data of the sensor device and the state of the sensor device are determined based on the element values of the transmitted extracted background noise using the same segments in the sorted arrays.
