In 1995 Nonin Medical revolutionized pulse oximetry with the Onyx. Hundreds of thousands of people trust Onyx, the first self-contained digital fingertip pulse oximeter.

The graph below shows the total number of publications each year in Low-Power Photoplethysmography Sensors and CMOS Technology.

This project reads raw RED and IR photodiode values from a MAX30102 pulse oximeter sensor via I2C, using an STM32F103C8T6 (Blue Pill). The data is transmitted over UART to a computer, where a Python ...
