A pulse measuring instrument based on STM32
Abstract：Pulse, as one of the parameters reflecting the important physiological information of human body, has become an indispensable part of modern medicine. This paper introduces a pulse measuring instrument based on STM32F103 core board and Bluetooth technology. The measuring instrument adopts the photoelectric sensor to realize the acquisition of the pulse signal, after the pulse signal processing, the data is displayed on the LCD1602.A mobile APP compiled by the easy for android development platform can easily realize the bluetooth transmission of the pulse signal and the subsequent data display and record, achieve one-button, automated pulse measurement. Compared with the traditional pulse measurement system, this measurement system is more concise and convenient, which meets the needs of daily self-examination. Moreover, it is low-cost, accurate and easy to record.
