MAXREFDES1043: How to Monitor SpO2 Levels Using the MAX30102


 Download Reference Design Document



Designed, Built, Tested

The Reference Design Document describes the hardware pictured below. It provides a detailed systematic technical guide to designing a device for measuring SpO2 using MAX30102. The hardware was built according to the linked Schematic, Bill of Materials and PCB Artwork. It was tested by Maxim’s expert applications engineering team in a state-of-the-art design lab and the Test Results are fully documented. Downloadable ECAD/EDA files are available in 7 different formats including OrCAD, Altium, Mentor DX Designer, Eagle and more.

Description

The MAXREFDES1043 is designed for SpO2 measurements based on Maxim’s new-generation biosensor—the MAX30102. The MAXREFDES1043 is a high-accuracy, low-power, small-size, and easily implemented design that can monitor SpO2 levels using red and IR LEDs. The MAX30102 is an integrated pulse oximetry and heart-rate monitor module. It includes internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection. The MAX30102 provides a complete system solution to ease the design-in process for mobile and wearable devices. It operates on a single 1.8V power supply and a separate 3.3V power supply for the internal LEDs. Communication is through a standard I2C-compatible interface. The module can be shut down through software with zero standby current, allowing the power rails to remain powered at all time.
