Since the power consumption of the light sensor is smaller than the power consumption of the display screen, the power consumption of the display screen set in the smart lock is solved. The smart lock consumes faster technical problems and achieves the technical effect of saving smart lock power consumption.

Specifically, the first optical signal detected by the plurality of optical sensors 10 may be an optical signal change trajectory formed by a plurality of sensors changing according to a certain regularity, and may be a light change signal having a certain changing frequency, such as a flicker having a certain frequency.

Optionally, a plurality of light sensors are arranged in an array. The 3*3 array shown in FIG. 2 may also be a 4*4 array as shown in FIG. 3, and the arrangement pattern of the array may be set as needed, which is not limited herein.
