Wireless remote control signal receiving module

The wireless remote control signal receiving module consists of ultra-regenerative wave detection, amplification and shaping circuits. Carrier high-frequency signal emitted by the remote control, by the receiving module capacitance and inductor, by the three-pole, etc. the receiving circuit sensing the signal amplification of the detection, sent to the three-pole amplification circuit for voltage amplification, and then sent into the integrated op amp for amplification, Data decoding after full recovery of the modulated signal in the remote control carrier signal is fed into the input pin of the microcontroller
