1. An electronic device comprising:
a sensor comprising a first node and a second node; and
a control circuit,
wherein the first node includes first electrodes and a part of third electrodes in a form of a metal mesh, and is operated as transmission electrodes,
wherein the second node includes second electrodes and another part of the third electrodes in a form of a metal mesh, and is operated as reception electrodes,
wherein the control circuit is configured to:
detect touch information related to an external object, at least based on a change of a capacitance between at least some first electrode of the first electrodes and at least some second electrode of second electrodes, and
detect hovering information related to the external object, at least based on a capacitance related to at least some third electrode of the third electrodes,
wherein the first node and the second node are disposed on a first layer, and
wherein the third electrodes are connected to each other through at least one bridge included in a second layer that is adjacent to the first layer.
