1. A contactless motion device comprising:
a substrate including at least one hole;
a body unit including a sensor unit, which is disposed around the hole in a plan view; and
a control unit connected to the sensor unit,
wherein
the sensor unit includes a first sensor, which transmits a first signal, and a second sensor, which receives the first signal,
the control unit is configured to determine whether a target object is inserted in the hole, based on the first signal received by the second sensor, and
the hole completely penetrates the substrate in a thickness direction, and
wherein the control unit is configured to determine whether the target object is inserted in the hole, if an intensity of the first signal received by the second sensor is repeatedly detected at least twice as being less than an intensity of the first signal transmitted by the first sensor by as much as a threshold value.
