Design of Smart Bracelet System Based on STM32 for People Prone to Thermoplegia

As the global greenhouse effect intensifies, summer temperatures continue to rise in some areas, leading to a surge in the risk of thermoplegia among outdoor workers. In view of this, this paper designs a smart bracelet system based on STM32, which includes an external sensor module, a communication module, a display module, and an alarm module, when the user works outdoors, the bracelet judge whether the user is at risk of thermoplegia through the health data collected by the external sensor module and transmits the data to the Android APP through the communication module, and issues a warning if there is a risk. In the physical test, it is found that the heart rate data processed by the original algorithm of the heart rate sensor (MAX30102) fluctuates greatly, based on this improving the original algorithm to reduce the data fluctuation by 44%. According to the results of physical testing, the optimized bracelet system has excellent performance and can meet the actual user requirements.
