Abstract

The proposed project is to build a medical device which will be able to detect and display human heartbeat graphically on computer screen. There will be two parts of the project that is the hardware and software. Hardware part begins with the transducer to detect the heartbeat on fingertip, followed by amplify and analyses the signal and then interfacing it with the computer. Transducer well works as . an optical sensor consist of LED as light source and LDR as receiver/ detector. Amplifier and analyzer circuit may consist of several op- amps that serve the function of amplifier, differentiator, and integrator components. The purpose is to count the signal to voltage form, amplify and convert it into suitable form that can be read by software through parallel port. The software part begins when the heartbeat signal from the computer port is read and calculates as a heart rate. This software is suggested to be written in C or C++ as it is an easy to learn programming language and lot of example from internet that can be refer to as a guide.
