Monitor and calculate your heart rate and blood pressure with this Blood Pressure Smart Watch and Heart Rate Monitor. Heart Attacks are the leading cause of death according to healthday.com so having a device that is able to inform you on your heart condition is very important.
The heart rate monitor is based on a difficult to pronounce technology called photoplethysmography, but it basically comes down to using green LED lights paired with light‑sensitive photodiodes to illuminate your skin and measures changes in light absorption.
