MAX30101 Heart Rate Sensor¶
A sensor application that demonstrates how to poll data from the max30101 heart rate sensor.
Building and Running¶
This project configures the max30101 sensor on the Hexiwear board to enable the green LED and measure the reflected light with a photodiode. The raw ADC data prints to the console. Further processing (not included in this sample) is required to extract a heart rate signal from the light measurement.
