A motion-detecting module for combining a light-emitting function and a light-sensing function together includes a chip unit, a cover unit, and a light-guiding unit. The chip unit has a PCB, a light-emitting chip, and an image-sensing chip, and both the light-emitting chip and the image-sensing chip are electrically disposed on the PCB. The cover unit covers the light-emitting chip and the image-sensing chip. The cover unit has a receiving space for communicating the light-emitting chip and the image-sensing chip, a first opening for exposing the light-emitting chip, and a second opening for exposing the image-sensing chip. The light-guiding unit is disposed under the cover unit, and the light-guiding unit at least has a first refraction surface, a second refraction surface, a third refraction surface, a fourth refraction surface, and a reflection surface.
