Biosignalsplux finger sensor for measuring blood oxygen saturation (SpO2) 4- and 8-channel connection

This optical sensor provides raw data on red and infrared (IR) light reflection for developers and researchers who want to develop their own algorithms for determining oxygen saturation (SpO₂) or related physiological measurements.

Unlike conventional SpO₂ sensors, this device does not directly calculate oxygen saturation values, but rather provides the raw sensor output data. This enables the development of custom algorithms in areas where highly precise optical biosignal data is required.

Applications range from biomedical studies and algorithm development to research in wearables, psychophysiology, and much more.

Compatibility: Operation of this sensor requires a Biosignalsplux data acquisition system, which is sold separately.

Features:

• Raw Data Output: Provides unprocessed reflection data in the red and infrared spectral range for algorithm development.
• Flexible Use in Research: Finger clip version for conventional setups; versatile version for experimental sensor placements.
• Suitable for multimodal research: Fully compatible with all biosignalsplux acquisition systems and combinable with other biosignalsplux sensors.
• Developer-Oriented: Ideal for researchers developing custom or experimental SpO₂ algorithms.
