What is "IoT"?

An abbreviation of Internet of Things,
which means "the communication of various objects over the Internet"
such as home appliances, automobiles and keys for home.
　IoT devices are sometimes referred to as "Connected Devices".

IoT may not be familiar to you right now,
but it may be coming closer from the IoT side,
as the movie "Detective Conan Zero the Enforcer"
features "IoT terrorism".
The movie was interesting.

By connecting home appliances and other items to the Internet and
using the "big data" obtained, we can connect them together and efficiently connect information and
products that meet individual preferences.
Originally, the Internet was used to connect "computer to computer" and was used for personal computers and "Server".

These days, digital information appliances such as TVs, recorders, and "Smart Speakers" can be connected to the Internet.

Everything around the world connected to the Internet is becoming an information transmission channel for communication.



In addition to "internet" and "IoT Compatible Devices" The server is required "sensor" built into the device recognizes the situation, sends it over the Internet to a server, uses a database in the server to determine the appropriate action, and sends it over the Internet to the device, which then operates. That's how it works.
※From "IT Passport School by Professor Kayanoki (2019/1)".


"Communications" such as smartphones and communications devices, were the most popular Internet of Things devices in operation in 2017.
However, as the market is mature, relatively low growth is expected in the future.
In the future, high growth is expected in the following areas: the spread of connected cars is expected to advance IoT "Automotive and transportation equipment", the market for digital healthcare is expanding "medical care", and smart factories and smart cities are expanding "Industrial use (Plants, infrastructure, and logistics)".

From these words and graphs, we can see that "Internet of Things is here."

However, as the number of operations increases, the risk also increases.

The number of IoT devices is increasing.

What we can do with "IoT"

Various objects, machines, human behavior, and natural phenomena generate enormous amounts of information.
Now that sensors can quantify information that previously could not be visualized, collecting this information can solve a variety of problems.
So what can we do? Here are some of them.

Easily check the operating status of plant equipment.

Control your appliances from the go. It can unlock your house keys.

Order items at home with one button.

A survey of the time elapsed since the sushi was placed on the plate and the popular Sushi toppings

Drone autopilot. It is also possible to spray agricultural chemicals based on the shape of fields.

Based on information obtained from IoT devices, companies can create products that meet customer needs.

The possibilities are endless.

Summary

  • 「IoT」..."Internet of Things" means that various things communicate via the Internet.
  • Everything connected to the Internet is becoming an information transmission channel for communication.
  • The number of IoT enabled devices will increase. now and in the future. The IoT era is just beginning.
  • Now that sensors can quantify information that wasn't previously visible, that information may be key to solving the problem.
  • "IoT terrorism exists!" It was even featured in a movie!
