Infrared remote control emission schematic diagram

This section introduces the microcomputer infrared air conditioner remote control composed of 80 pins using Samsung's THBT-T01/THBT-R01 dedicated transmitter/receiver chip . KFR-24GW(J) type is an electronic control system for wall-mounted air conditioners, which uses wireless remote control and LCD display. The remote control consists of an infrared remote control
transmitter and an infrared remote control receiver.
    (1) Remote control transmitter 1) Remote control transmitter function and composition: The front of
    the remote control transmitter is equipped with an infrared command signal radiation window of purple organic transparent glass. The function of the transmitter is to generate and transmit to the front space a modulated 38kHz modulated signal. The infrared ray is used to control the operation and shutdown of the air conditioner to better realize various functions of the air conditioner, and can display wind speed, temperature, timing and other functional symbols on its own LCD screen. Figure 18-7 is the schematic block diagram of the transmitter .
