Abstract: A rear alarm sensor assembly includes: a sensing part that generates waves and a sensing signal, based on contents obtained by detecting an approaching object by the generated waves; a controller that generates a transmission signal including the sensing signal and an identifier for identification and transmits the generated transmission signal to a body control module, the controller including a plurality of identification terminals for changing the identifier according to a connection relation and a ground terminal that is grounded; and a determination device that is electrically connected to the ground terminal and moves so as not to be connected to the plurality of identification terminals or so as to be connected to one of the plurality of identification terminals. In particular, the determination device electrically connects the connected identification terminal and the ground terminal to change the connection relation of the plurality of identification terminals.
