Device for sensing and collecting wrist motion

The invention discloses a wrist motion sensing and collecting device which is provided with a shell, the shell is provided with a panel and a back plate, a sensing area is arranged in the shell, and a sensor comprises a light-transmitting plate on the back plate, a lens group above the light-transmitting plate and a two-dimensional matrix photoelectric sensor above the lens group. A pulse time sequence light source is arranged on the side face of the lens barrel in the shell, a lens set is arranged between the pulse time sequence light source and the induction area, and a light source emitted by the pulse time sequence light source is emitted out of the transparent plate through the lens set. The wrist motion sensing device is suitable for wrist motion sensing collection under the motion condition, the two-dimensional matrix photoelectric sensor is used as an information collector, a folded light path is adopted, the height of the device is greatly reduced, and the device can be assembled in a wristwatch. 本发明
