Measuring Heart Rate and Blood Oxygen Saturation with Arduino UNO: High Accuracy!
This project uses an Arduino UNO board connected to the MAX30102 module (pulse oximeter and heart rate monitoring module), along with an OLED display and a buzzer for BPM measurement.
BPM stands for "beats per minute", which is about 65-75 for a normal person at rest, and may drop below this during sports activities. SpO2 indicates the oxygen saturation level, which is generally above 95% for a normal
