Measuring Blood Pressure, Heart Rate, and SpO2 Using MAX32664D

Abstract: The MAX32664D is a variant of the MAX32664 sensor-hub family, which is specifically targeted for finger-based measurement of blood pressure, heart rate, and SpO2. Combined with the MAX30101 pulse oximetry and heart-rate monitor module and powered by Maxim's BPT algorithm, it provides sensors’ raw data, as well as calculated systolic and diastolic blood pressure, 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 MAX32664D, and to calibrate, configure, and receive measurement and monitoring data.
