AFE4490 PPG/SpO2 driver for ESP32-S3
What is incunest_afe4490?
incunest_afe4490 is an open-source driver for the TI AFE4490 pulse-oximetry front end on the ESP32-S3, computing SpO2 by the ratio-of-ratios method, heart rate three ways (peak detection, autocorrelation and FFT with harmonic product spectrum) and perfusion index, each with a signal-quality index. It is part of the IncuNest open neonatal incubator project and is not clinically validated.
