Měření vlastností BOSU v průběhu rehabilitace

Abstract

The issue of the thesis is realized by measuring the pressure and orientation in a space on rehabilitation utility BOSU with wireless transmission via BLE to PC. The wireless data transmission was choosen OLP425i – 04 connectBlue from U – blox. For measuring the pressure inside the BOSU was selected a pressure sensor 2SMPP – 03 from Omron. For measuring the space orientation was choosen inertial sensor MPU9250 from TI. Data transmission is performed using an external serial SPI bus and A/D converter. The circuit is powered by a four AA battery with a total voltage of 6 V. Electrical connections are on two PCBs. Job description realization of a functional prototype for measuring orientation in a space and create the user interface for displaying and saving data to csv file for further processing.
