Biosignalsplux – Versatile Sensor for Measuring Blood Oxygen Saturation (SpO2) 4- and 8-channel Hubs

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

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 high-precision 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.

Special Features:

• Raw Data Output: Provides unprocessed red and infrared spectral reflection data 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 their own or experimental SpO₂ algorithms.
