Abstract:The traditional electrode-lead heart monitoring systems are wired, and contact with skin, high power consumption. This paper form the non-contact, light, low-power, to conduct a suit based on MSP430-RF wireless heart monitoring system development. This paper designs the hardware functional circuit, and completes the PC preparation process. The system can measure the pulse waveform to the body in real-time, and calculate the number of heartbeats per minute, with a graphical interface displayed. The system has been achieved and can be run.
