Shown is a miniature remote control receiver and control circuit. The remote control signal reception, amplification, filtering and shaping circuit adopts MC 3373 integrated
circuit. The infrared photodiode receives the control signal from the remote control transmitter and is input through pin ⑦. The signal input from pin ⑦ is amplified by the automatic gain control amplifier in the integrated circuit
, and then undergoes frequency selection, filtering and shaping. Pin ① outputs the control pulse and sends the pulse signal to
the @ pin of the control integrated circuit. The control circuit @, The @, ⑤, @, ◎ pin output control signals control the relays K1-K4 through the drive transistors, and then the relays control
other parts.
