The datas for the design collected by photoelectric pulse sensor, the pluse sensor works by the transmission of light,to detect the change of blood concentration with the change of light intensity, result in voltage changing. The data converted to the digital signal on the bluetooth development board,and broadcast constantly .The application on the android could start bluetooth of the equipment and gained the broadcasting bluetooth signal, then established a connection and access to data services, received the pulse signal in realtime state. The data would be processed by algorithm in application, saved in the text file, and realtime waveform is given in the chart on the view of the wave form, the application could calculate the current heart rate of tester, and then application could show the the healthy condition of the tester according to the heart rate . Other functions such as registration, and static display can be achieved by adding the corresponding code in the application,such approach ensure the accuracy of the data and add the necessary function, enrich and perfect the application, make it can be widely used.
