      Enable the sensor framework so accelerometers, gyros, temperature sensors,
      etc. can register unified data channels. Depends on GPIO for interrupt
      pins. Disable if no sensors are present.

        help
          Opt in to the redesigned sensor framework (v2) that updates the device
          APIs and CLI tools. Only enable if your BSP/drivers support it.

        help
          Build the shell command helpers for listing and testing sensors. Useful
          during bring-up; disable to save a bit of code.
