Smart watch
Everyone's health awareness has been greatly improved. In addition to wearing masks and washing hands frequently, many people have begun to use the most advanced technology to monitor their health status. At the same time, smart watches, as the most suitable wearable devices for monitoring health, have gradually gone out of the public eye.
Although smart watches are similar in appearance to traditional watches, they provide far more functions than traditional watches. The latest smart watches provide functions including apps and notifications synchronized with smart phones, fitness and health monitoring, location services, voice commands, payment, and wireless charging.
Most smart watches on the market generally have problems in all aspects. They are either too old-fashioned in style, or they are not fully functional, and their battery life is not enough.
With the advantages of low power consumption and high performance, the control system with integrated circuit STM32F205 series microcontroller as the core can well meet and inprove the above requirements.
ST provides a series of solutions to meet the needs of the most advanced smart watch design.
