Description
MAX30100 Pulse Oximeter Heart Rate Sensor Module
The MAX30100 Pulse Oximeter Sensor Module is an integrated solution for measuring both pulse rate and blood oxygen saturation (SpO2). It functions as an optical sensor, using two onboard LEDs—red and infrared—to emit light through a finger or earlobe. A photodetector then measures the varying absorbance caused by pulsing blood, allowing it to calculate real-time heart rate and SpO2 levels accurately.The MAX30100 module includes a complete pulse oximetry subsystem featuring ambient light cancellation (ALC), a 16-bit sigma-delta ADC, and a proprietary discrete-time filter to ensure precise measurements.
