SpO2 Sensor (with clip)

SpO2 Sensor (Finger Clip )

The SpO2 (peripheral capillary oxygen saturation) sensor uses two emitting 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 that is sent via SPI. This sensor can be used to estimate the oxygen saturation level on the blood with +/- 2% accuracy compared to a medical sensor.
