Design of Wireless Motion Sensor Node

Abstract

The wireless transmission node designed in this report receives the data generated by the ECG detection module, temperature measurement module, and exercise statistics module by using the STM32 single-chip microcomputer system. STM32 sends the results after digital signal processing and algorithm calculations to the mobile terminal, realizing the dynamic display of electrocardiogram, body temperature, exercise volume and monitoring of arrhythmia. We separately debug the function and stability of each module and finally integrate it into a system. Experimental tests show that the system can display various data more accurately and achieve corresponding functions.
