Featuring a 14mm x 14mm PCB mount size and supported by example C code for Arduino and mbed, it enables easy integration into wearable health devices. Its dual LED system alternates red and infrared light to measure oxygen levels and pulse rate non-invasively, making it ideal for next-gen biometric applications. ## Description Description: A pulse oximeter measures blood oxygen saturation in the bloodstream. Because oxygen saturation can reflect early medical problems such as heart and lungs, this reading is useful as a general health monitoring indicator. Its working principle is based on the absorption properties of hemoglobin in the blood. Oxygenated hemoglobin absorbs more infrared light than red light, while deoxyhemoglobin absorbs more red light than infrared light. Therefore, the red and infrared LEDs in the oximeter alternately emit light, and the photodiode receives an optical signal that is not absorbed. The ratio of red and infrared light received by the photodiode is used to calculate the percentage of oxygen in the blood. Based on the pulsating nature of the arterial blood flow, the pulse rate and intensity are also determined and displayed during the measurement.

However I marked it down because of this: 1. Heart actually tracks pretty good with a store-bought unit and I included a TFT display to show HR over time as I moved about. 2. O2 shows as 100% continuously and it should be 96% based on the store-bought unit. 3. Ambient temperature is reasonably accurate but body temp is a few degrees below my body temp. Maybe skin resistance??? I have not looked to see if there is a way to calibrate for O2 readings.
