An aperture ratio measurement sensing device is provided. The aperture ratio measurement sensing device comprising a light sensing module and a signal measurement module is used for measuring a distance/angle to which a motion object in a use state is moved/opened with respect to an opening portion. The light sensing module is disposed on a structure of a building near the motion object. The signal measurement module is used for measuring a light signal received by the light sensing module, and determining the aperture ratio of the opening portion according to the intensity of the light signal. |
