SOUND WAVE SENSOR, CORRECTION VALUE SETTING DEVICE, AND DISTANCE DETECTING DEVICE

摘要

A sound wave sensor (10) in a distance detecting system determines the presence of an object and the distance to the object by receiving, at a preset sensitivity, a reflected wave obtained from a transmitted sound wave reflecting off the object. A correction value for correcting the sensitivity of the sound wave sensor is acquired from outside the sound wave sensor, and this correction value is used to correct the sensitivity (S210, S220).
