+
+- `name`: This field defines the string name used by `wb_robot_get_device()` to get the `WbDeviceTag` handle of this sensor. Its default value is "accelerometer".
+
 - `lookupTable`: This field optionally specifies a lookup table that can be used for mapping the raw acceleration values [m/s²] to device specific output values.
 By default the lookup table is empty and therefore the raw acceleration values are returned (no mapping).
 See the section on the [DistanceSensor](distancesensor.md#lookup-table) node for more explanation on how a `lookupTable` works.
