MAX30100 Pulse Oximeter Heart Rate Sensor Module TF Mini The LDR module also hasMAX30100 Pulse Oximeter Heart Rate Sensor Module MAX30100 Pulse Oximeter is 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. This particular LED colour combination is optimized for reading the data through the tip of ones finger. It is fully configurable through software registers, and the digital output
