Zest_Sensor_IMU
Overview
The Zest_Sensor_IMU is an electronics development board for 6TRON open source platform, that provides a 9-DOF (nine degree of freedom) absolute orientation system and an environemental sensor (humidity, pressure, temperature).
The board includes the following elements:
-
BNO055 provides an absolute orientation system. This component also integrates a data fusion core.
-
BME280 measures hygrometry, temperature and pressure. It can be used for thermal drift compensation.
-
3 axis axelerometer, magnetometer and gyroscope
Two gyroscopes can be used, which may help to compensate angular acceleration drift. The temperature / pressure sensor can be used for thermal drift compensation.
Since multiple sensor can be used all together, the Zest IMU provide redundancy and can be used to test complex data fusion algorithms.
The onboard EEPROM can save calibration data. Optionaly, the Zest IMU can wake the Zest Core up on motion.
