Through smart watches, users can record exercise, sleep and health (heart rate, blood pressure, blood oxygen, body temperature, etc.) data in real time, synchronize these data with iOS or Android devices, and guide the role of healthy life through the data.
Step counting function
Using a 3-axis gravitational accelerometer to detect movement caused by the development and progress of wearable technology, in the future wearable devices will be implanted bumps to calculate the number of steps, and then according to certain principles to eliminate the wrong count to get the final Results.
Heart rate monitoring
Use a reflective photoelectric sensor to collect photoelectric signals to monitor and calculate the changes in pulse blood volume, and then calculate the basic parameters that reflect the human heart rate according to the relationship between the absorbance of the substance in the blood and the concentration.
Body temperature detection
Use the thermistor to convert the temperature change into the resistance value change, and then use the corresponding measuring circuit to convert the resistance value into a voltage, and then convert the voltage value into a digital signal, and then perform the corresponding processing on the digital signal to get the temperature value.
Energy consumption, sleep monitoring
The sensor monitors the person's movement, heart rate and body frequency by touching the wrist, and calculates and knows the sleep status and energy consumption of the subject. Different products have different algorithms.
The smart bracelet also has a social network sharing function. For example, users can share sleep quality, diet and exercise status, and mood records through binding apps. For the elderly, it is also a protector. Through the built-in GPS connector, it can notify the relevant hospital or family members of the relevant physical condition and location at any time.
