DIY Blood Oxygen Meter

via Random Stuff We Make on instructables

The main component of this project is:

Max30102 Oximeter Sensor: The MAX30102 is an integrated pulse oximeter and heart rate monitor biosensor module. It integrates a red LED and an infrared LED, photodetector, optical components, and low-noise electronic circuitry with ambient light suppression. – The MAX30102 features a 1.8V power supply and a separate 5.0V power supply for internal LEDs for heart rate and blood oxygen acquisition in wearable devices, worn on the fingers, earlobe, and wrist.

We will be connecting our sensor with the ESP32 board to take inputs & show the monitored oxygen level in Blynk app on our smartphone.
