Description
This optical sensor provides raw red and infrared (IR) light reflection values for developers and researchers aiming to build their own algorithms for oxygen saturation (SpO₂) or related physiological metrics.
Unlike standard SpO₂ sensors, this device does not compute oxygen saturation values directly instead provides the raw sensor output. This enables custom algorithm development in domains requiring high-fidelity optical biosignal data.
Applications span biomedical studies, algorithm prototyping, wearable research, psychophysiology, and more.
Compatibility: This sensor requires a biosignalsplux data acquisition system to function, which is sold separately.
