Blood Oxygen Saturation (SpO2) Sensors

A biosignalsplux SpO2 sensor designed for oxygen saturation level estimations in the finger.  Using two LED’s, one in the red region and the other in the infrared region of the spectrum the reflected light of each one of these LED’s is absorbed by a photodiode that converts this current into a digital value, from which the blood oxygen saturation can be derived.

The finger clip form-factor enables a user-friendly application on the finger (commonly the index finger), without any additional accessories being required for the use of this sensor. The individual intensities of the LEDs can be controlled both using the OpenSignals (r)evolution software, Biosignals Studio (Android app) or the biosignalsplux APIs, enabling a location-specific light intensity configuration of this sensor.

Various versions of this sensor are available:

• Finger Clip Sensor (4 & 8 Channel Hubs)
• Finger Clip Sensor (Hybrid 8 Hub)
• Versatile Sensor (4 & 8 Channel Hubs)
• Versatile Sensor (Hybrid 8 Hub)
