Pulse Oximeter Demonstration Kit Using dsPIC33FJ128GP DSC Family

dsPIC33FJ128GP Family Pulse Oximeter Demonstration. The ability to measure heart rate and blood oxygen level is now being added to consumer products. These measurements can be taken using pulse oximeters that are intended for home medical use and by integrated wrist-worn fitness activity trackers. A pulse oximeter is a device that uses a non-invasive method for measuring the oxygen saturation level of a person's blood, as well as their heart rate. LEDs in pulse oximeter demonstration transmit two wavelengths of light through a finger to a photo detector. The pulse oximeter demonstration can measure changing absorbance at each of the two wavelengths, process and then filter the data to determine the blood oxygen saturation level and heart rate. The Pulse Oximeter Demonstration Board was implemented using the dsPIC33FJ128GP802 Digital Signal Controller
