Remote control receiver 1
) The composition and functional circuit of the remote control receiver:
The remote control receiver is a special integrated circuit equipped with a photosensitive diode , model GK409. The photosensitive diode inside the integrated circuit
receives the infrared carrier signal from the transmitter, and the decoding circuit outputs the control signal. The working voltage V(l) of the infrared remote control receiver is 5v. Figure
18-9 is the schematic block diagram of the remote control receiver .
