Fitness tracker
Health is always the most concerned topic.
Products such as exercise trackers have become very common wearable devices in our lives. They can collect our daily exercise data and sleep conditions, and then help us develop a healthier lifestyle.
Most exercise trackers have built-in accelerometers and gyroscopes, and can also calculate calorie burning and sleep tracking.
In addition to these basic functions, it can even measure the height of our climbing stairs, daily food intake, etc., and even some have built-in GPS positioning functions, which can track exercise data more accurately.
The main design challenge faced by such devices is how to provide low power consumption and high accuracy in a cost-effective manner in order to track common activities, specific exercises, heart rate, and calorie consumption.
With the advantages of low power consumption and high performance, the control system with integrated circuit STM32F103 series microcontroller as the core can well meet and inprove the above requirements.
