Pulse monitoring system was designed with integrated AD module in micro-controller chip and the feedback algorithm. HK-2000B-type sensor was used for collecting the pulse signal. Customize the design process, some components, the preparation of the LCD driver and display the menu; in addition, by using the results of the feedback signal sampling algorithm improves the measurement accuracy. After a long and diverse system of the test, the accuracy and stability while significantly reduce the measurement time, with high practical value.
