  • Publication number: 20180308349
    Abstract: A bidirectional wireless infrared relay control device includes an infrared reception module connected to a microprocessor module. A remote controller of an external electric appliance is sent by the infrared reception module to the microprocessor module for decoding. A selection module is connected to the microprocessor module and provides the microprocessor module with a set code signal of transmission or reception. A first wireless processing module is connected to the microprocessor module. The microprocessor module cooperates a code from the selection module to generate a radio frequency signal to be transmitted by the first wireless processing module. A second wireless processing module is connected to the microprocessor module. The second wireless processing module is set by the microprocessor module and the selection module to receive the radio frequency signal. An infrared transmission module is connected to the microprocessor module. A control method of using the control device is also disclosed.
