Design and implementation of wearable oxygen saturation monitoring system

In this paper, a wearable oxygen saturation detection system based on MAX30102 and STM32F411 is designed. In the process of system design, MAX30102 integrates multiple LEDs, photodetectors, optical devices and low-noise electronic circuit with ambient light suppression, which improves the anti-interference ability of the detection module, the running speed and signal processing ability of the system, reduces the development time and power consumption of the system, and provides multi-platform support for the intellectualization of the system. In the signal processing algorithm of the system, a variety of filtering algorithms are designed for comparison, and the algorithm with better performance suitable for the system is selected to achieve a more accurate design of wearable oxygen saturation detection system.
