fitness tracking device with the help of the Adafruit 9-DOF BNO055 motion sensor and Node MCU to keep track of the physical models, in this case, a human in vector space. The data from the sensors was wirelessly transferred to the Arduino IDE with the help of Internet protocols using a WiFi module built within Node MCU. From that data, the linear acceleration and velocity was calculated, and noise and integration errors were mitigated with the help of the Kalman filter and complementary filter. Finally, that data was transferred to modeling software from a database.
