Idea
This project aims to build a sensor to detect the oxygen concentration in the blood.
Blood oxygen sensors typically operate on optical principles. The most common type of blood oxygen sensor is the pulse oximetry (SpO2) sensor. The SpO2 sensor utilizes the light absorption characteristics to measure the oxygen saturation level of hemoglobin. It works by emitting two different wavelengths of light (usually red and infrared) through the skin into the blood, and then measuring the intensity of the light that is reflected back through the skin using corresponding photoelectric sensors. Based on the difference in absorption of red and infrared light, the oxygen saturation level in the blood can be calculated.
