wireless wearable pulse oximeter sensor

Abstract

This project aim is designing a wireless wearable plus oximeter .there is two unit , the first one to measure ,calculate and transmit the heart rate and the oxygenation (sensor unit). The second unit contains from the receiverand PC to receive the data and display it in the PC using graphical user interface (PC unit) . the design is unobtrusive comfortable for long term wear ,portable ,low power consummation and remote monitor .there are many people who will benefit from the ability to have a constant with plus oximeter that does not interfere with their daily activities . similar products are expensive and offer Less options. The sensor unit is consists of a soft silicon ,preprocessing circuit ,processing unit and transmitter circuit . the soft silicon houses the LEDs (light emitting diode ) and photodiode necessary for obtaining plus oximeter data ,preprocessing circuit for convert the current to voltage and filtering the signal , processing unit to calculate the heart rate and the oxygenation and transmitter circuit to transmit the data using radio frequency to the second unit . The PC unit consists of RF receiver , microcontroller unit ,USB to UART and PC .The RF receiver to receive the data from transmitter in wave form ,the microcontroller unit to obtain the data from the signal ,the USB to UART to convert the data from serial to UART and contact the receiver circuit with PC and PC using for display the data using GUI.
