What are the functions of the smart band?
Step counting function
Use a 3-axis gravitational accelerometer to detect movement caused by the development and progress of wearable technology. In the future, wearable devices will use implant bumps to calculate the number of steps. Then eliminate the wrong count according to a certain principle to get the final result.
Heart rate monitoring
Use reflective photoelectric sensors to collect photoelectric signals to monitor and calculate changes in pulse blood volume. Then according to the relationship between the absorbance of the substance in the blood and the concentration is proportional. The calculation reflects the basic parameters of the human heart rate.
Body temperature detection
Use the thermistor to convert the temperature change into the resistance change. Then use the corresponding measuring circuit to convert the resistance into a voltage. Then the voltage value is converted into a digital signal, and then the digital signal is processed accordingly to obtain the temperature value.
Synchronously
Smart bands still cannot get rid of the dependence on terminal hardware and software. After all, after collecting a large amount of data, we still need to synchronize the data with the corresponding APP of the band. Only to be able to achieve permanent recording and analysis functions. Therefore, is the synchronization method between the smart band and the mobile phone or computer convenient enough? It is also a major factor affecting user experience.
