Infrared Transmitter and Receiver Module

This is infrared receiver module can
receive the modulated infrared signal of
38KHz that is sent by the IR transmitter
module and demodulate it into logic
level, ie, when it gets the modulated
infrared signal, it outputs one negative
pulse and returns to normalcy (High
level). The infrared receiver module and
transmitter module can complete the
infrared remote control with the codec
program.
