Sensor-Based IoT Architecture

Before its recent rebranding as “IoT,” the Internet of Things concept began emerging with devices like the now famous Coke® machine at Carnegie Mellon University (CMU), which since the 1980s has been self-monitoring its internal stock of soft drinks. It monitors how long each bottle has been cooling in the machine and stores this information on a server for access via faculty and students’ computer terminals before they make the long trek to their beloved fueling station.
