Max30102 Heart Rate Sensor Module

A pulse oximeter measures blood oxygen saturation in the bloodstream. Becauseoxygen saturation can reflect early medical problems such as heart and lungs, thisreading is useful as a general health monitoring indicator.Its working principle is based on the absorption properties of hemoglobin in theblood. Oxygenated hemoglobin absorbs more infrared light than red light, whiledeoxyhemoglobin absorbs more red light than infrared light. Therefore, the red andinfrared LEDs in the oximeter alternately emit light, and the photodiode receivesan optical signal that is not absorbed. The ratio of red and infrared light received bythe photodiode is used to calculate the percentage of oxygen in the blood. Based onthe pulsating nature of the arterial blood flow, the pulse rate and intensity are alsodetermined and displayed during the measurement.
