This universe of connected objects has resulted in the concept known as Internet of Things (IoT). This paradigm suggests that all objects that surround us are interconnected through Internet, having their features and uses globally and ubiquitously available. Therefore, IoT can be considered a technological ecosystem that can be used in order to resolve multiple problems and generate new services.
Thanks to the use of IoT, is possible to obtain more information on systems and their processes, reduce costs, create new city or company management services or even increase accessibility to information by the citizens. Perhaps, maybe due to its origins, IoT can be easily explained, in a simplistic way, as an asset of electronic devices that, through Internet, can obtain information and interact with people in a specific context. However, the real potential of IoT is way broader and barely known as of today. Initiatives surrounding IoT are nowadays on the rise, and they hold high expectations of expansion and economical and social impact. To a certain degree, it could be said that IoT supports (or even absorbs in some cases) other concepts such as Smart City, Industry 4.0, wearables, etc.
