Wireless internet connection validating identity
For example, a stepper motor can be set to a specific direction that might be represented in device state data, while a microphone might be steadily sampling data in terms of frequencies, which is best transmitted as telemetry.
These components are connected to the logic systems of the device through a hardware interface.
Each form of information might best be handled by a different backend system, and each system should be specialized around the data rate, volume, and preferred API. Examples of metadata fields include: State information describes the current status of the device, not of the environment. Operational information is data that's most relevant to the operation of the device as opposed to the business application.
This section lists and describes common categories of information found in Io T scenarios. This might include things such as CPU operating temperature and battery state.
The specific requirements of your application will help you understand whether something that generates information should be treated as a device, and therefore deserves its own ID, or is simply a channel or state detail of another device.
As an example, consider a project that has the goal of monitoring the temperature of rooms in a hotel.
Internet of Things (Io T) is a sprawling set of technologies and use cases that has no clear, single definition.
If you are doing gas detection, the type of gases that the sensor can accurately detect matters.
Note the average temperature field in the second example. Is metadata from each sensor most valuable on its own, or do the separate pieces of metadata make more sense applied to the room as a whole?
What if the room was a suite and the three locations were the bathroom, lounge, and bedroom?
The specific use cases and opportunities across different industries are numerous, and in many ways the world of Io T is just getting started.
What emerges from these scenarios is a set of common challenges and patterns.

Common examples of platforms include single-board-computers such as the Beaglebone, and Raspberry Pi, as well as microcontroller platforms such as the Arduino series, boards from Particle, and the Adafruit Feather.
