ChapTeR 1 ■ The InTeRneT Of ThIngs and daTa
Notice here you see things connected to the Internet in logical groupings. Observe the connected
plants. The drawing depicts several sensors, but each sensor isn’t necessarily connected directly to
the Internet. It is more likely and more practical to connect the sensors from one or more plant to an
intermediate node that sends the data either to a service on the Internet or perhaps to another node in the
network for later processing. Figure 1-3 shows how this would look in a logical form.
