Infrared communication is a common, inexpensive, and easy to use wireless communication technology. IR light is very similar to visible light, except that it has a slightlty longer wavelength. This means IR is undetectable to the human eye – perfect for wireless communication. For example, when you hit a button on your TV remote, an IR LED repeatedly turns on and off, 38,000 time a second, to transmit information (like volume or channel control) to an IR photo sensor on your TV.
This Mini Slim remote control provides 17 function keys with firing distances of up to 8 meters. IR receiver module can receive standard 38KHz modulation remote control signal, through programming, you can achieve remote control signal decoding operation.
