- This project report describes the design and implementation of a system that measures blood oxygen saturation (SpO2) and heart rate (BPM) using the MAX30102 pulse oximeter and heart rate sensor module. The MAX30102 module is a highly sensitive and accurate sensor module that detects the light transmitted through the blood vessels in the fingertip to measure SpO2 and BPM. The hardware design of the system includes the MAX30102 module, an Arduino Uno board, and an OLED display. The MAX30102 module is connected to the Arduino Uno board through the I2C interface, and the OLED display is connected to the Arduino board through the SPI interface. The system is powered by a USB cable connected to a computer. To ensure that the MAX30102 module operates correctly, a voltage level converter is used to convert the 5V signals from the Arduino board to 3.3V signals that can be used by the MAX30102 module. The software design of the system includes a MAX30102 library and a main program written in Arduino IDE. The MAX30102 library is a set of functions that controls the MAX30102 module, including functions to initialize the module, configure the LEDs and photodetector, and read the raw data from the module. The library also includes functions to process the raw data and calculate the SpO2 and BPM values. The main program reads the raw data from the MAX30102 module and processes it using the functions provided by the MAX30102 library. The SpO2 and BPM values are then displayed on the OLED display. The paper concludes that the MAX30102 module is an effective and reliable sensor module for measuring SpO2 and BPM values and can be used in various health monitoring applications. The system can be further improved by integrating wireless communication modules, such as Bluetooth, to enable remote monitoring and data storage. Additionally, the MAX30102 module can be integrated into wearable devices for continuous health monitoring.
