The importance of pulse measurement and the limitations of existing pulse measuring instruments are first introduced. Then, the design scheme is detailed, including hardware design and software design. The hardware design part mainly includes the design of the signal acquisition module, data processing module, and display module. In the signal acquisition module, the pulse signal is obtained through sensors, and after amplification and filtering, a clear pulse waveform is obtained. The data processing module processes the collected signals through a single chip, calculates parameters such as heart rate, and displays the results on an LCD screen. The software design part mainly involves writing single-chip programs to implement signal acquisition, processing, and display functions. Finally, the design is experimentally validated, and the results show that the designed pulse measuring instrument has high accuracy and stability and can meet the practical needs of use. Keywords: Pulse measuring instrument; single chip; hardware design; software design; experimental verification.
