Why doesn't Wukong remote control have a verification code?

The reason why Wukong remote control has no verification code is that there is no pairing response. The battery is low. It is recommended to replace the battery of the remote controller, and then press the reset button to reset. Whether the polarity of the remote battery is reversed. The place where the remote controller is placed is beyond the remote control range, or the remote control signal cannot be sent because there are foreign objects blocking the remote control transmitting window and the remote control signal receiving window. The remote control doesn't display, it's humid, so it's recommended to blow dry with a hair dryer or direct sunlight, and then change the battery for observation.

Remote control principle

The remote control system generally consists of three parts: the transmitter remote controller, the receiver and the central processing unit (CPU), in which both the receiver and the CPU are on the TV. The TV remote controller generally uses infrared emission control information with the wavelength of 0.76 to 1.5 micron, and its working distance is only 0 to 6 meters, and it propagates along a straight line. In the internal circuit of the remote controller, corresponding to each key on the remote controller, the internal circuit adopts a specific coding method to correspond to it.
