Bluetooth Pulse Oximeter using Max30100, and Arduino Nano– In this tutorial, you will learn how to use the Max30100 Pulse Oximeter with Arduino Nano and display the Heart Rate and Blood Oxygen on a 16×2 I2C supported LCD Module and also send the blood oxygen and heart rate or Pulse rate values to the android application designed in Android Studio using the wireless Bluetooth technology. The Heart rate or Pulse rate or Heart beat is measured in BPM which is also known as the beats per minute while the Blood Oxygen Concentration is measured in percentage.
In this picture above you can see the BPM and SpO2 values on the I2C supported 16×2 LCD. You can also monitor the same values on the android cell phone application.
If you are near to the circuit, you can directly read the Blood Oxygen and BPM values on the LCD, and if away, then you can use your android cell phone application and monitor the Blood Oxygen and BPM values wirelessly.
