A motion-detecting module includes a PCB, a light-emitting unit, and a light-sensing unit. The light-emitting unit is electrically disposed over the PCB. The light-sensing unit has a light-sensing die electrically disposed on the PCB and a package cover covered on the light-sensing die, and the package cover has a through hole corresponding to the light-sensing die and a transparent element disposed in the through hole. The present invention does not need extra package protection body of the prior art for protecting the light-sensing die during the transport of the light-sensing module. The present invention use original package cover to prevent the light-sensing die from being damaged by external force, and the original package cover shelters the light-sensing die from extra stray light.
