Pulse Oximeter Project

Overview

This project aims to develop a wireless pulse oximeter using Arduino and various electronic components. The pulse oximeter measures oxygen saturation levels and pulse rate, transmitting the data wirelessly to a PC for display and analysis.

Objectives

• Measure oxygen saturation (SpO2) and pulse rate.
• Utilize Arduino and MAX30101 sensor for data acquisition.
• Implement wireless communication using XBee modules.
• Display and analyze sensor data on a PC.

Components

• Arduino Uno R4
• MAX30101 Sensor
• XBee Modules
• LED and Button Shield
• Breadboard and connecting wires

Setup and Installation

1. Hardware Setup:

   • Connect the MAX30101 sensor to the Arduino using the I2C interface.
   • Attach the XBee modules to the Arduino for wireless communication.
   • Ensure the LED and button shield is properly connected.

2. Software Setup:

   • Install the Arduino IDE.
   • Install necessary libraries: Wire, SoftwareSerial.
   • Upload the provided Arduino sketches to the respective boards.

Project Structure

• src/: Contains all the Arduino code for different stages of the project.
• pdf/: Includes datasheets for the MAX30101 sensor and other components.

Usage

1. Data Acquisition:

   • Place your finger on the MAX30101 sensor.
   • The sensor will measure the oxygen saturation and pulse rate.

2. Data Transmission:

   • The Arduino will transmit the sensor data wirelessly using XBee modules.

3. Data Display:

   • Use the MATLAB scripts to visualize and analyze the received data.
