EASY plug IR Receiver Module


Infrared receiver is a component with functions of reception, amplification, and demodulation. The internal IC has already been demodulated so that can directly output digital signal.
Well, it will be also easy to make your own IR controller using IR transmitter.
This module should be used together with EASY plug control board.

Special Note:
The sensor/module is equipped with the RJ11 6P6C interface, compatible with our keyestudio EASY plug Control Board with RJ11 6P6C interface.
If you have the control board of other brands, it is also equipped with the RJ11 6P6C interface but has different internal line sequence, can’t be used compatibly with our sensor/module.
