A nine-step guide to designing and building Internet of Things solutions

A growing number of businesses are turning to the Internet of Things (IoT) to improve the way they operate. Metyis experts explain how to get started.

The Internet of Things is a concept that describes physical objects (or groups of objects) incorporating sensors, processing capability, software, and other technologies that connect and exchange data over the Internet.

The concept allows physical objects to communicate with the digital world, creating a data information network that can lead to improvements and advancements in multiple areas. The Internet of Things is already prevalent in homes, vehicles, medical areas, factories and more today – but as the technology matures, the number of use cases is increasing day by day.

Building an Internet of Things network, however, is easier said than done. Based on the pioneering work that Metyis is conducting in the Internet of Things landscape, the consultancy firm’s experts outline a nine-step journey that guides the successful development and deployment of IoT solutions:

1. Definition of needs
Every IoT network is unique in its specifications, requiring the manufacture of custom technologies, called embedded systems, a combination of computer hardware and software. The key is to ensure that the definition of requirements is framed and that the business and technical capabilities are brought together to achieve the desired end state with a system solution.

2. Block designs
The first step is to create the whiteboard block designs that form the architecture of the device, outlining the different components and how they will work together.

3. Firmware development and prototype assembly
The team then develops the firmware that will run inside the device, determining its behavior and communication protocol. Firmware development is an ongoing process; Although all boards are prepared to be fully functional, some features are added at different stages depending on the needs of the project.

4. Prototype terrain
During the prototyping phase, the focus is on the development of an industrialized product. This prototype demonstrates the possibilities of connecting sensors to the Internet.

5. Schematic designs
Schematic designs provide a more detailed view of all system components and how they are connected. It also includes the data stream and definition of signals that have been assigned. A schema can also contain a revision list showing changes made to the original design.

6. PCB design phase
Moving forward in the circuit board design phase, schematic designs are translated into physical connections by taking pre-existing chips and turning them into electronic boards, installing and distributing components on the board, and defining their sizes. Samples are then made with a view to industrialization.

7. Printed circuit board production
In this phase, the production of the printed circuit board begins. The printed circuit is the bed that will receive all the components; these are compiled and customized, preparing it to undergo an industrialized pilot.

8. Functional tests
The system then goes through rigorous testing, debugging and validation phases to ensure the device is effective and safe. Trust is of the utmost importance for any IoT solution, which can be vulnerable to information attacks.

9. Industrialized Pilot
The pilot validates if what is produced is suitable for industrialization, if the IoT network will operate in the desired environment and if the device can be mass-produced.
