While the Barometer application involves basically all the environmental sensors on the SensorTile.box, the Compass&Inclinometer application is almost uniquely focused on inertial measurement. The app data processing is more complex that in the previous case, and the overall flow consists of Inputs (the Sensors), Functions (the data elaboration) and one Output (stream to BLE). The used function, the sensor fusion oriented to the calculation of the Euler angles (which describes the orientation of a rigid body in the 3D space), is widely described across ST literature (see for example UM2225, DT0060, DT0075). The source of the high accuracy of the described application are of course the sensors:
- 6-axis inertial measurement unit (LSM6DSOX)
- 3-axis accelerometers (LIS2DW12)
- 3-axis magnetometer (LIS2MDL)
The below pictures are really very beautiful... and accurate 😎 Have a look �?�
