Max30102 Module

English | 简体中文

---

Environment and Relevant Pins：

This program is based on STM32F103, with SCL pin connected to PC12, SDA pin to PC11, and the INT pin of MAX30102 connected to PB5.

Functionality：

It can measure heart rate (HR) and blood oxygen saturation (SpO2) and display the data on a 0.96-inch OLED screen every second.

Description：

The data is processed using the official algorithm, which calculates the results after collecting 100 data samples per second.

Limitation：

Before starting the calculation, the official algorithm collects 500 reference data samples. I currently believe that these reference samples should be based on the finger's infrared data. If anyone has other insights, feel free to share.
