Open source bio-logger for monitoring and recording inertial movement
Résumé
There is a growing interest for bio-logging and the measurement of animal or human motion. However, most of the technical solutions are commercial and therefore fit hardly to particular needs. Here, we describe in details an Arduino-based stand-alone logger featuring a 32-bit microcontroller, an IMU, a Bluetooth link and a SD card. Angular speeds and 3D orientations measurements (roll, pitch and yaw angle) of the hydrofoil are done at a sampling frequency of 100 Hz while the kiteboard is moving in the open sea. Software and hardware design are made fully available on an open archive to facilitate the development of such device.
