-All student had to know about the presentation and the proposal as well as the submition date of both .

-Get the information about the methodology .

Methodology

              in this project ppg is a sensor placed on a thin part of the patient's body, usually a fingertip. Light of two different wavelengths is passed through the patient to a photodetector. The changing absorbance at each of the wavelengths is measured, allowing determination of the absorbances due to the pulsing arterial blood alone, excluding venous blood, skin, bone, muscle, fat, and in most cases nail polish .With this sensor it is possible to measure both oxygenated and deoxygenated hemoglobin on a peripheral scale .

  

This project is aimed to design and construct an interfacing circuit for data acquisition using a commercial pulse oximeter sensor.  The oximeter sensor which comprises of a red LED, an infra red LED and a photo-detector is to detect the pulse volume change to monitor the change in blood vessel re-activity  And also required to design the driver circuitry. utilize a NI DAQ card and to program using Labview for circuit control, data acquisition and data saving for future data processing .

Result & Analysis

-Get he knowledge about the methodology of this project .
