Smart watch K1

 Selling point 2: It uses an optical detection method: light is emitted by the machine to shine on the skin of the hand, when the blood flows through the capillaries, there is a slight change in the brightness of the light (the depth of red), the sensor detects the change in the reflected light, and through an algorithm the heart rate value can be derived. The sensor detects the change in the reflected light and uses an algorithm to derive the heart rate value. The colour is also used to determine which condition it currently belongs to, red for anaerobic endurance, orange for aerobic endurance, yellow for extreme and green for fat burning.

Application scenario: When you need to do aerobic or anaerobic exercise, you can always know your current heart rate value, so you can exercise more effectively.               Selling point 2.

No intervention, no operation is required to have 24 hours of testing data a day, this is the form of heart rate testing devices should be, more humane than similar products on the market with testing, and can generate daily, weekly and monthly heart rate reports, clearly understand whether your heart rate is up to standard, anytime and anywhere to understand their health status.                  Selling point three.

High-frequency continuous heart rate monitoring is what makes it medically valuable; not only is heart rate an independent factor in death in hypertensive patients, but sudden cardiac death, which seems to have no means of prevention, can actually be predicted by continuous heart rate monitoring, and high-frequency accurate monitoring of heart rate and collection of heart rate values over a continuous period of time can truly predict the occurrence of malignant cardiovascular events.

 Selling point four.

From the statistical values of heart rate during sleep one can even deduce which points in time one is not sleeping soundly, which points in time one is sleeping deeply and which points one is having nightmares, which is more helpful for one's own health detection!

Selling point five.

The continuous heart rate measurement allows you to record the entire process of heart rate values, which is very useful for both daily life and exercise. The heart rate values and statistics allow us to see how efficiently we are exercising when doing different exercises, so that we can make adjustments to the type and frequency of exercise. This is a killer feature for real fitness or weight loss users.
