IR Infrared transmitter receiver

The infrared decoding and encoding module adopts MCU+infrared emitting head+infrared receiving head, which leads out the serial port of MCU to connect other devices that need infrared control, and can be used as infrared wireless data communication and data transmission. It has NEC format infrared code transmission function, which can control 99% NEC infrared format equipment, such as most TV sets, set-top boxes, DVDs, electric fans and other electrical equipment. It only needs to use the serial communication knowledge of the single chip microcomputer to send the specified command through the serial port to transmit the control module; the infrared decoding operation is performed through the serial port receiving mode to obtain the remote control coding information. You can also use the store’s USB to TTL combined with the computer to control other devices. After connecting the circuit, the computer host computer software can simply send and receive commands to realize the codec function. Two modules can complete the transceiving operation.
