20 * A model representing a tree of sensors that are available from the daemon.

22 * This model exposes the daemon's sensors as a tree, based on their path. Each
23 * sensor is assumed to be structured in a format similar to
24 * `category/object/sensor`. This model will then expose a tree, with `category`
25 * as top level, `object` below it and finally `sensor` itself.
