The operating temperature range of the module is -40C to +85C.
LED Current range 0mA to 50 mA.
LED Pulse width range from 200us to 1.6ms
The MAX30100 Pulse Oximeter is a medical device that is used to measure blood oxygen saturation levels, heart rate, and pulse strength.
It uses a non-invasive method to measure oxygen saturation levels in the blood.
This module has a pair of LEDs (Light Emitting Diode) that emit a monochromatic red light at a wavelength of 660nm and infrared light at a wavelength of 940nm.
As the photodiode emits light, it falls on the finger and gets absorbed by the oxygenated blood rest light is reflected through the finger and falls on the detector.
The detector detects and processes the signals and gives the output.
The MAX30100 sensor works on the I2C Serial Communication protocol
