Connection method: Bluetooth connection wii host Usage time: about 15 hour Power supply mode: built-in 2 AA alkaline batterie Motion Sensor: With kinetic energy sensing function, it can detect the change of the controller's stereo tilt. The G-Sensor accelerometer senses the movement of the handle to detect the swing force, direction and the tilt angle (linear gravity acceleration and center of gravity) of the Wiimote when the player controls the Wiimote. Built-in MotionPlus detects the real-time rotation direction and force (such as rotation vector and angular velocity) when the player controls the Wiimote. CMOS Sensor Sensor: detects the infrared light of the Sensor Bar, obtains the light point movement information, and provides the Bluetooth indicator movement information. Support the host sensitivity switching function, with a sound module inside to convey the sensing sound sent by the Wii game host. MotionPlus: Gyroscope can be used to detect the real-time rotation direction and force (such as rotation vector and angular velocity) of the player when manipulating the Wiimote, to increase the control fun in the interactive game. Connection terminal of expansion device: Nunchuk and other compatible peripheral devices can be connected. Packaging: 1. Left handle * 1/2 2. Right handle * 1/2 4. Instructions * 1/2 (As shown in the figure)
