 `TiltSensor` sensor mode constants:
-- MODE_2AXIS_SIMPLE - use `callback(state)` for 2-axis simple state detect

-- MODE_3AXIS_SIMPLE - use `callback(state)` for 3-axis simple state detect
-- MODE_3AXIS_FULL - use `callback(roll, pitch)` for 2-axis roll&pitch degree values
-- MODE_BUMP_COUNT - use `callback(count)` to detect bumps
