Abstract: A sensor terminal includes: a vibration sensor; an L-shaped attachment main body portion on which the vibration sensor is mounted and that is detachably attached to a truncated quadrangular pyramid structure portion of a valve cap attached to an opening/closing shaft portion of a water regulating valve provided in a water service pipe; side surface magnets that are provided in the attachment main body portion; and an upper surface magnet that is attached to a lower surface of a base on which the vibration sensor is mounted. Further, the truncated quadrangular pyramid structure portion includes a quadrangular upper surface and four side surfaces, and the attachment main body portion of the sensor terminal is fixed using magnet to each of the upper surface of the truncated quadrangular pyramid structure portion and at least one side surface among the four side surfaces.
