Design of wearable sports monitoring equipment based on low-cost sensor

Abstract

Physiological parameters during the exercise are instructive. According the heart rate, body temperature and etc, users could improve their sport performance, and be beneficial to their health. In addition, such equipment is generally large and weight, inconvenient to carry, and relatively expensive. Therefore, it is of practical significance to study and design a health feedback device with light weight, easy to carry and low price, and use its physiological parameters to guide exercise. Therefore, this article designs a sports monitoring device based on Low-cost sensor, controlling the number of steps, heart rate temperature sensor through MCU, and feeding back the physical parameters such as distance, steps, average speed, heart rate, body temperature and other physiological parameters through LCD in real time to improve the effect of sports. After the hardware circuit is simulated by Multisim, use Altium Designer to design the PCB board of the circuit, and realize the system function with the help of Keil uVision5 modular programming. The system test results show that the system works normally, runs stably, and can accurately provide various physiological parameters. In addition, the whole device is light in weight and high in performance, which can well meet the portability under sports conditions and has certain practical value.
