The pulse which can reflect human’s physiological health is the most common and important physiological phenomenon. Many clinical diseases, particularly heart disease, can make the change of the pulse. Therefor, pulse information detection and processing has very important practical value and significance in clinical medicine. Traditional pulse detector almost use the form of online direct detection, so that the flexibility of detection devices is lower and not apply to ordinary families. Aiming at this problem, in order to improve the method of traditional measuring, the paper puts forward the proposals based on the research of wireless communication technology. The single chip microcomputer technology is the kernel of the signal collection, processing, wireless transmission and control. Acquisition unit is ST188 photoelectric sensor. Combining nRF24l01 wireless module, the paper realized the pulse data acquisition and processing, and the wireless transmitting and receiving and pulse data display through designing the hardware and software. Experiments states that the pulse detector has the advantages of accuracy detecting data and high efficiency. At the same time, pulse testing instrument is exquisite, easy to carry, low cost, and convenient to use for the ordinary families.
