Design of wireless motion monitoring device based on STM32
In order to collect,record and display the user's ECG information,the body surface temperature and the movement information stably,the control system is designed with STM32F103C8T6 single chip microcomputer.The system is composed of temperature sensor,six axis gyroscope,ECG detection module and so on.The design algorithm realizes the monitoring of human movement information through the contact temperature sensor LMT70 and high-precision analog front-end chip ADS1292.ADS1292 can transmit the user's ECG signal to the controller by collecting the bioelectrical signal and processing it with filtering algorithm.Read the MPU6050 acceleration sensor data to get the user's walking distance,and get the number of steps according to the step frequency,so as to meet the step counting requirements.Through the wireless module upload synchronization,achieve a variety of data in the server to achieve more intuitive display.The actual test shows that the scheme is effective and meets the design requirements of heart rate monitoring and motion measurement.
