Development and Realization of Heart Rate Detection System

A heart rate measurement system is developed with pure hardware method and the heart rate measurement is realized through the collection and processing of Electrocardiograph(ECG,the same below). The test results show that the system can obtain clear ECG,accurately measure and display the heart rate. It is not only comprehensive and practicable,but also the accuracy require-ments and cost of components are low. Therefore,it is very suitable for the experimental project of electronic circuit teaching in univer-sities. The training of this project can not only improve students' ability to design circuits and solve practical problems,but also culti-vate students' systematic research ability and innovative spirit.
