Abstract: This paper introduced the design of a wireless PCG monitor based on nRF24L01.The controller is STC12C5A60S2with a 8bit MCU.10bit ADC in STC12C5A60S2is used to convert the PCG signal which has been out of the amplifier and filter.The data will be writen in the memory of nRF24L01and be transmitted.The receiver takes the data and sends them to computer for display and analysis.The result of testing shows that the indoor communication is well and waveform of PCG meets the requirements.In addition,the communication protocol and the program were also analyzed.

Key words: Wireless transmission,nRF24L01,Phonocardiogram(PCG)
