Abstract: The blood pressure and the pulse are two of important physiology parameters of human body, accurate measurement of the blood pressure and the pulse are playing vital role to the human body health. The principle of this instrument is pulse wave characteristic of time. It chooses the special pressure sensor BP300 which converts precisely the pressure signal to voltage signal and makes signal processing by the 8-bit SCM——ATMEGA16. The LED displays circulatory the results——systolic pressure, diastolic pressure and pulse. The instrument can be used conveniently and the results are presented obviously.
