<p>This invention provides a detection sensor, which enables a communication of setting information without a dedicated communication means, and a setting information acquisition method therefor. In particular, the output of the output signal Sc as well as the reception of the setting information data D are conducted using the common external connecting terminal 15d, by means of selectively enabling the second output circuit 21, whom the pressure sensor 10 essentially includes, and the input circuit 22 commonly connected to the external connecting terminal 15d that is connected to the second output circuit 21.</p> |
