: rgb(33, 33, 33); This is a MAX30100 Pulse Oximeter sensor module. It is an integrated pulse oximeter and heart-rate monitor sensor solution. It's an optical sensor that derives its readings from emitting two wavelengths of light from two LEDs-a red and an infrared one-then measuring the absorbance of pulsing blood through a photodetector. The pulse oximetry subsystem in MAX30100 Pulse Oximeter Module consists of ambient light cancellation (ALC), 16-bit sigma delta ADC, and proprietary discrete time filter. It has an ultra-low-power operation which makes it ideal for battery operated systems. MAX30100 operates on a supply in the range of 1.8 to 3.3V. Pin Configuration VIN - Input voltage (1.8V to 5.5V) SCL - IIC-SCL SDA - IIC-SDA INT - MAX30100INT IRD - MAX30100 IR_DRV RD - MAX30100 R_DRV GND - Ground Specifications High Sample Rate Capability Fast Data Output Capability I2C interface plus INT pin It is an integrated pulse oximetry and heart rate monitor sensor solution. Integrated LEDs, Photo Sensor, and High-Performance Analog Front -End Complete Pulse Oximeter and Heart-Rate Sensor Solution Simplifies Design Measures absorbance of pulsing blood Ultra-Low-Power Operation Increases Battery Life for Wearable Devices Programmable Sample Rate and LED Current for Power Savings Ultra-Low Shutdown Current (0.7uA) High SNR Provides Robust Motion Artifact    : rgb(33, 33, 33);
