1. A sensor that is connected to a control apparatus via one of two communication buses formed in a moving body and is identified by a unique identifier, the sensor comprising:
a communication terminal that is connected to either one communication bus or another communication bus of the two communication buses, and communicates with the control apparatus;
a plurality of identification terminals each having a connection state that is one of an open state in which the identification terminal is not connected to any potential and a grounded state in which the identification terminal is connected to a ground potential; and
an identifier setting section comprising one or more processors that execute computer-executable instructions stored in a memory, wherein the one or more processors execute the computer-executable instructions to cause the identifier setting section to set the identifier of the sensor according to the connection states of the plurality of identification terminals and a difference in the communication bus to which the communication terminal is connected, wherein:
the one or more processors execute the computer-executable instructions to cause the identifier setting section to set the identifier with a different pattern according to whether the communication bus to which the communication terminal is connected is the one communication bus or the other communication bus,
the control apparatus includes a first control apparatus that controls a first control target and a second control apparatus that controls a second control target; and
between a case where the sensor is included in a first sensor group that communicates with the first control apparatus and a case where the sensor is included in a second sensor group that communicates with the second control apparatus, a correspondence relationship between the communication bus to which the communication terminal is connected and the connection states of the identification terminals is interchanged.
