Operating Principle • Signal Demodulation ： • Receiving antenna receives high-frequency signal sent by transmitter. The signal will go through capacitive coupling, frequency-selecting circuit to receiving demodulation unit. Finally, the demodulation module demodulates the code signal from the radio-frequency signal of transmitter and the code signal will be transited to MCU as control data signal.
