1. A sensor device for a diaper, the sensor device comprising:
a first protective layer;
at least one pad positioned on an upper part of at least a part of the first protective layer;
a flexible body layer positioned on upper parts of the at least one pad;
a shield plate layer positioned on an upper part of at least a part of the flexible body layer;
a second protective layer positioned on upper parts of at least a part of the shield plate layer and at least a part of the flexible body layer; and
a printed circuit board layer positioned on an upper part of at least a part of the second protective layer or at least a part of the flexible body layer,
wherein the sensor device is attached to an outer side of the diaper,
wherein the at least one pad is provided in a plural, and
wherein when measuring a change in capacitance value by using at least one of the at least one pad, a measuring power voltage is applied to a corresponding pad and a ground voltage is applied to remaining pads excluding the corresponding pad.
