1. A sensor comprising:
a processor;
a control circuit configured to be set to a first operation mode in which an operation is prepared by receiving a clock signal and an operation command from the processor, wherein the control circuit is configured to generate a first signal including a result of an operation corresponding to the operation command, and a second signal indicating completion of the operation; and
an interface circuit configured to transmit the first signal and the second signal to the processor, wherein
the control circuit is further configured to be set to a second operation mode due to not receiving the clock signal, which is discontinued by control of the processor in response to a transmission of the second signal and
wherein, after receipt of the second signal, the processor is configured to evaluate, based on the first signal, whether a motion of an object has been detected.
