Aiming at the problems of the existing pulse acquisition devices being expensive, large in size, poor in flexibility and scalability, this paper proposes to use CC2530, which integrates microprocessor and RF functions, as the main control chip of the pulse sensing node. CC2530 controls the signal acquisition, processing and transmission of the sensing node, and realizes power consumption management and task management. The experimental results show that the sensing node designed has the characteristics of low power consumption, high accuracy, strong real-time performance, stability and reliability, small size, high flexibility and easy operation.
