MAX30100 Heart Pulse Sensor

 

With the MAX30100 integration of this sensor, it offers a pulse-oximeter and heart rate sensor together. The LEDs on it send two lights of different wavelengths (Red and Infrared), and it measures the absorption in the blood circulation with these lights and the photodetector on it. With this sensor, you can reach accurate results with fingertip measurements.

 

The signal from the LEDs can be used with Arduino or another microcontroller along with the I2C output. INT Pin is also available. It can be powered by 3.3V.
