Abstract
An electronic device includes: a first sensing device, for selectively detecting a state of motion of an object at a first frequency; a second sensing device for selectively detecting the object to determine whether the object is in a specific space at a second frequency, wherein the second frequency is different from the first frequency; a light emitting device, for illuminating the object to make the first sensing device able to detect the state of motion of the object; and a control unit, coupled to the first sensing device and the second sensing device, for controlling operating states of the first sensing device and the second sensing device.
