Introduction
The SparkFun Pulse Oximeter and Heart Rate Monitor is an I²C based biometric sensor. Utilizing two chips from Maxim Integrated, the SparkFun Pulse Oximeter and Heart Rate Monitor has both the MAX30101 biometric sensor and MAX32664 biometric hub. While the former does all the sensing, the latter is an incredibly small and fast Cortex M4 processor that handles all of the algorithmic calculations, digital filtering, pressure/position compensation, advanced R-wave detection and automatic gain control. We’ve combined them and written an Arduino Library with example code demonstrating basic to advanced features to help get you started utilizing the SparkFun Pulse Oximeter and Heart Rate Monitor into your next project. Or if you’re looking to put these IC’s into a final product, Maxim has provided some features to get FDA approval. Let’s get started!”
