Hua Yun 36 Key Universal IR Video Remote Control HY-053
The general remote control device is composed of infrared transmitter and receiver two parts. In the TV world, we now call this transmitter the TV remote control. The remote control can be used to control household appliances within 10 meters. The operation process is: 1. The infrared light wave emitted by the infrared transmitter contains the remote control signal; 2. 2. After receiving the signal, the infrared receiver on the TV will demodulate the low-frequency control signal in the modulated infrared light wave and send it to the switch controller to complete the function to be controlled by the user.

Customized 38 Key Wireless Universal IR TV Remote Control HY-182
Operation of infrared remote control:
First of all, the principle of the infrared remote control is that the transmitting head transmits signals, the receiving head receives signals, this is obvious, everyone knows. The transmitter transmits the modulated signal, this point also needs to be clear, that is, the encoded carrier signal.
Remote control no matter learning, or actual work, is the transmission of signals. When learning, the signal of each protocol is transmitted, because the receiving head can only receive the fixed protocol, so only the fixed protocol will respond.
In actual operation, there will be overlap. At this time, you will find that there is some misoperation.
