The present invention provides a sensor system with which a change in the state of a workpiece which has occurred in a conveyance process can be detennined. The sensor system comprises: a plurality of sensors positioned along a line and measuring data indicating that a workpiece being conveyed upon the line has passed thereby; a plurality of slave units respectively connected to the plurality of sensors and acquiring the data measured by the plurality of sensors; and a master unit connected to the plurality of slave units. The master unit comprises: a storage part for storing the data in association with information which relates to the timing at which the data was measured; and a determination part for comparing the data transmitted from two or more of the plurality of slave units using the information which relates to the timing, and determining a change in the state of the workpiece.

Sensor system

Provided are a sensor unit and function activation method that make it possible to collectively activate the functions of a plurality of sensor units. A sensor unitwhich can be connected to other sensor unitsto form a unit series, comprises an activation unitfor activating a prescribed function on the basis of a signal from the outside and a signal output unitfor outputting a trigger signal for activating a prescribed function to the outside on the basis of a signal from the outside.
