Imagine at home, your refrigerator connected to the internet and have a temperature sensor, that sensor provides information about the temperature inside the refrigerator through your phone. As you noticed that it is now easy to control its temperature wherever you are, all you have to do is to get a good connection to the internet.

But what does it mean? From a technological point of view, the refrigerator -in this case- is an IoT device. As a concept, it is any device being connected to the internet and easy-controlled. If you have multiple devices, they form a system which attempts to create a great connection between the physical and digital worlds.
