1. A wearable device comprising:
a housing comprising a transparent part;
a circuit board which is disposed in the housing and comprising:
a first surface facing the transparent part, and
a second surface opposite to the first surface;
a processor connected to the circuit board;
a first sensor module comprising:
a first light emitter configured to emit light toward the transparent part,
a first light receiver configured to receive light from the transparent part,
a first integrated circuit (IC) layer comprising a modulator electrically connected to the first light emitter and the first light receiver so as to modulate light received on the first light receiver and in which at least one of the first light emitter or the first light receiver is disposed, and
a second IC layer electrically connecting the first IC layer to the processor and disposed on the first surface or the second surface of the circuit board; and
a second sensor module comprising a second light emitter and a second light receiver,
wherein the first light receiver and the second light receiver are respectively disposed at opposite peripheries of the first IC layer,
wherein the first light emitter and the second light emitter are disposed between the first light receiver and the second light receiver, and
wherein the circuit board, the second IC layer, and the first IC layer are sequentially stacked in a direction perpendicular to the first surface or the second surface.
