Smart Bracelet features pedometer function, heart rate monitoring, temperature detection, energy consumption, sleep monitoring, synchronization mode, network function.
1, pedometer function: the use of 3-axis gravity accelerometer, detection of movement caused by With the development and progress of wearable technology, the future wearable devices will be implanted bumps to calculate the number of steps, and then according to certain principles to exclude the wrong counting so as to get the final result.
2, heart rate monitoring: the use of reflective photoelectric sensors, the collection of photoelectric signals to monitor the calculation of pulse blood volume changes, and then according to the absorbance of substances within the blood is proportional to the concentration of the relationship, the calculation of the reaction to the basic parameters of the human heart rate.
3, body temperature detection: the use of thermistor temperature change is converted into a change in resistance, and then the corresponding measurement circuitry to convert the resistance into voltage, and then the voltage value is converted to a digital signal, and then the digital signal to the corresponding processing can be obtained temperature value.
4, energy consumption, sleep monitoring: the sensor through contact with the wrist, monitoring human movement, heart rate and frequency of body movement, the calculation of the subject to be informed of the state of sleep and energy consumption, the algorithm is different for different products.
5, synchronization: smart bracelet still can not get rid of the end of the hardware and software dependence, after all, in the collection of a large amount of data, we still need to synchronize the data with the corresponding APP bracelet, in order to achieve a permanent record and analysis of the function. Therefore, whether the synchronization of smart bracelets with cell phones or computers is convenient enough is also a major factor affecting the user experience.
6, network function: smart bracelet also has a social network sharing function, for example, users can sleep quality, diet and exercise and mood records through the binding application to share. For the elderly, it is also a protector. Through the built-in GPS connector, it can always inform the relevant hospital or family members of the physical condition and location at any time.
