IR decoding coded wireless serial transceiver module
Product Features :
( 1 ) using NEC format encoding can decode remote control codes, remote control home appliances ;
( 2 ) The default is 5V power supply , to use 3.3V power supply, please contact customer service description ;
( 3 ) The default serial port baud rate 9600 data bits, 1 stop bit , no parity , baud rate if other instructions , please contact customer service ;
( 4 ) 3 m effective communication distance, if the communication distance is more than 3 m in need of special instructions ;
( 5 ) at 9600 baud data transmission : 400ms interval of time pass 18 bytes , data loss does not occur ;
( 6 ) transceiver module structure, the yellow light flashes when data is sent , the red light flashes when data is received , more convenient test ;
( 7 ) in the industrial control , home appliances widely used, has a strong anti-jamming capability , information transmission reliability, low power consumption , and low cost ;
( 8 ) Module size : 50MM * 30MM * 15MM.
Module comprehensive details of the show :
The GND TXD RXD SCM system or computer system TXD pin serial port module , RXD and modules , GND and module to module provides power 3.3 ~ 6V , and can be used normally . As fixed baud rate of the serial port you can use the same to the "fixed baud , 8 data bits, no parity ," communication format of serial devices can be wired directly replace the original serial port without the need to modify the program
(1) serial communication functions: with two modules linked by the chart method is good, you can achieve infrared wireless serial communication, the method is suitable with wireless serial communication between the microcontroller and the microcontroller, but also for wireless communication between the microcontroller and the computer.
(2) Infrared remote control decoding functions: turn the infrared wireless serial module connected to the computer through a USB port, open the serial debugging software, set the baud rate and receives hexadecimal display with remote control at the receiver press the button, the corresponding key code can be sent to the display interface serial debugging software. This feature is limited to use NEC-coded remote control.
(3) appliance remote control function: first the need for remote control decoder, then the remote control key codes sent through the serial port module, you can achieve this key function.
