The infrared receiver module has a built-in infrared receiving tube and it can receive the infrared light signal sent by the infrared transmitting module.
The infrared receiving module has a built-in infrared receiving tube, which can convert the optical signal emitted by the infrared transmitting tube into a weak electrical signal. The signal is amplified by an IC internal amplifier, and then restored to the original code emitted by the remote control through automatic gain control, bandpass filtering, demodulation and waveform shaping, which is input to the code recognition circuit on the electrical apparatus through the signal output foot of the receiving head. It can identify and receive the digital signal emitted by infrared.
The nature of its work is similar to that of IR emitter, except that it is a transmitter and a receiver, which are combined and used together to achieve infrared wireless data transmission.
It can cooperate with the IR emitter module, or use the infrared remote control to send the signal, and the IR receiver module receives the signal.
