| Abstract: | This article expose how to transform human's pulse signal into pulse voltage by applying photoelectricity transformation principle. How to divide the voltage in four frequency parts by frequency division and how to measure accuratcly the pulse interval after division by single chip microcomputer 89C2051. Finally reproduce the pulse heatiny per minute on the screen. |
