Working Principle of MAX30100

The MAX 30100 works based on photoplethysmography (PPG). The sensor emits red and infrared light into the skin using its LEDs. Blood flow changes with each heartbeat, altering the amount of light absorbed or reflected. The photodetector measures these changes, and internal signal processing converts them into heart rate and SpO2 data.

• Heart Rate: Detected by pulse-induced blood volume changes

• SpO2: Calculated using absorption differences between red and IR light

This non-invasive method allows safe and continuous monitoring.

SpO2 Measurement Explanation

SpO2 represents the percentage of oxygenated hemoglobin in the blood. The MAX30100 calculates this by comparing how red and infrared light are absorbed by oxygen-rich and oxygen-poor blood. This technique is commonly used in medical pulse oximeters.
