PLUX Blood Oxygen Saturation (SpO2) Versatile Sensor with 4- & 8-Channel Hubs

The Blood Oxygen Saturation (SpO2) Versatile Sensor with 4- & 8-Channel Hubs is designed for oxygen saturation level estimations in the finger using two LEDs, one in the red region and the other in the infrared region of the spectrum. The reflected light of each one of these LEDs is absorbed by a photodiode that converts this current into a digital value, from which the blood oxygen saturation can be derived.
