ChapTeR 1 ■ The InTeRneT Of ThIngs and daTa

On the left side of Figure 1-3 are the IOT devices. These could be a simple sensor, an entire sensor
network, a device with one or more sensors, an embedded microcontroller solution with sensors, a more
sophisticated microprocessor-based solution, or even a device such as a microwave oven, alarm clock, or
television. Some devices will connect directly to the Internet, as shown at the top of Figure 1-3. These devices
are the more sophisticated devices with built-in networking capabilities. At the bottom are devices that will
connect to intermediate nodes such as data aggregators, computers, and so on, that filter, augment, and
store the data prior to either presenting it via an Internet connection or sending the data to cloud services.
At the far right is a user accessing the data via the Internet or a cloud service. Naturally, this can be any type
of device such as a laptop, desktop, tablet, phone, watch, or other smart device or appliance (including
another IOT device).
