This Blood Pressure Smart Watch with Heart Rate Monitor is the perfect tool to help you keep tabs on your heart rate and blood pressure. According to healthday.com, heart attacks are among the top causes of death, so having a device to warn you on your heart condition can be a real life saver.

This ThinkBand Smart Watch will do even more than simply warning you on your heart condition, as it can detect other health problems as well.

How do Smart Wrist Watches detect your heart beat on your wrist?

The name of the technology that powers such devices is called photoplethysmography. Despite of its fancy name, it actually boils down to using green LED lights and light-sensitive photo-diodes that measure light absorption changes on the surface of your skin. 

This enables the device to measure how much blood flows through your vessels at any given time. Since blood is red, it absorbs green radiation and reflects red one. 

As your heart beats, it pumps more blood through your wrists, resulting in a greater absorption of green radiation. Between two beats, the blood flow decreases.

The sensors are able to compensate for low signal levels, this being the reason why these LED lights flash hundreds of times per second. The result is an excellent accuracy of the measurements.

When the device measures your heart rate at ten minutes intervals, it switches to using infrared radiation. If this method fails to provide proper readings, the watch switches back to the LED lighting method.

If you want the sensor to work as claimed by the manufacturer, you have to wear your watch close to the skin. The manufacturer recommends that you tighten your wrist in case you notice that the sensors aren't doing their job as they should.

In conclusion, the heart rate sensor in this device is a very useful feature, particularly for fitness aficionados. If you enjoy checking your heart rate during workouts, this watch will offer you the accuracy and the reliability you need to track your vital parameters at any given moment.
