Measuring SpO2 and Heart Rate Using MAX32664C


The MAX32664C is a variant of the MAX32664 sensor-hub family, which is specifically targeted for measurement of SpO2 and heart rate. Combined with the MAX86141 optical sensor and a 3-axis accelerometer, it provides the sensor’s raw data, as well as calculated SpO2 and heart-rate data, to a host device through its I2C slave interface. This document provides step-by-step instructions that enable a user to communicate with the MAX32664C and to calibrate, configure, and receive measurement and monitoring data.
