Real-Time Health Tracking to Maintain Your Fit Life-Style

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. 

This powerful Blood Pressure Smart Watch and Heart Rate Monitor does not only inform you about your heart rate, but also detects various health problems as well!

Connect easily with your smart phone to get insights about your health using the mobile Health App present for both Android and iOS phones.


How does FitBand Smart Watch measure the heart beat on the wrist?

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.

This lets the device detect the amount of blood flowing through your wrist at any given moment. Because blood is red, it reflects red light and absorbs green light.


“When your heart beats, the blood flow in your wrist — and the green light absorption — is greater. Between beats, it’s less,”.

The sensor are designed to compensate for low signal levels by increasing both LED brightness and sampling rate. That’s why the heart rate sensor on the back of the device flashes its LED lights hundreds of times per second, helping the device calculate heart rates precisely.


But when it measures your heart rate every ten minutes, the Watch switches to using infrared light. And if it fails to provide an adequate reading while using the infrared light, the device switches back to the green LEDs.

In order for the sensor to work as advertised, the Watch must be close to your skin. The company advises tightening the band in case the sensors aren’t reading your heart rate accurately.

All in all, the heart rate sensor in the Watch is a great feature, especially if you’re something of a fitness buff. It checks your heart rate during workouts for an at-a-glance overview of both the intensity level and the heart rate change over time.

 For the problem that the bracelet can measure the heart rate in things and in the air, the following explanation is made:

1.At present, the mainstream heart rate bracelets on the market adopt the same measurement method. The principle is not complicated, that is, the PMG signal of the radial artery is obtained by the reflective photoelectric measurement method, and the fast Fourier transform is performed on the PPG signal to analyze the frequency domain. To achieve the detection of the human heart rate. To put it simply, it is to use a light to the artery and then reflect it back. Based on the change of the reflected light, the heart rate of the human body is calculated.

2.Due to many factors such as the physiological structure of the human body, the color of muscles and blood, green light is the color with the highest passing rate in the human body. Therefore, the light source of the heart rate sensor uses green light to achieve minimum loss and interference.

3.Heart rate wristband detection focuses on human tissue. Some data is also read for non-human objects. This is a known and normal phenomenon. After the data is based on the principle of light reflection, the heart rate detection will have a reading. This situation cannot be All avoided, so there will be problems with heart rate data in the case of heart rate bracelet (table) in the case of "air test".
