MAX30003 is a single lead ECG front-end chip that has an inbuilt function for heart rate detection (R-R detection). This  makes it perfectly suited for any wearable application that can detect the ECG signals of the heart.

So what makes it perfect for most wearable applications is that there is low power consumption ie. just 85 uW of power and can work from 1.1v. Also for the fact that you do not need three electrodes and can very well do without the third leg (Black). This device becomes ideal for clinical as well as any fitness applications. Heart rate stands for the number of times the heart pumps blood per minute. Keeping this in mind the chips is designed to measure the R-R detection between two successive peaks in the QRS complex of the ECG. The board is a easy to use device that does not require any kind of microcontroller to aid in Heart rate computation.

Note: This is a not a medical certified device nor is it intended to be used as one. While this product has the potential to work as a full-fledged patient monitor, careful calibration has to be performed and safety precautions need to be taken. We recommend usage only with a battery power source or an isolated source.
