Today, the term IoT (Internet of Things) has become more popular, but what is IoT and how does it work? In this article, we will present the essence and helpfulness of the Internet of Things (IoT).

What is the Internet of Things, IoT?

The Internet of Things, or IoT, is a set of Internet-connected things that have the ability to receive and transmit over a network. An example of the Internet of Things is smart homes that can change lighting or heating levels. In simple terms, IoT refers to all objects and devices that are connected to the Internet, such as smart watches, refrigerators, security systems, etc.

How does the Internet of Things work?

The IoT system works by collecting and transmitting data in real time. It consists of the following components:

Smart device

They are the devices that have acquired new functions and capabilities thanks to sensors, processors, Internet connection and the support of certain technologies. Almost all smart devices have the following features: can collect and analyze data from built-in and external sensors, are connected to the Internet or other devices via Wi-Fi, Bluetooth, and can interact with other devices to exchange data and receive commands for execution.

IoT applications

An IoT application combines data from smart devices. Such applications use artificial intelligence technologies or machine learning to analyze the data received.

Where and how is the IoT system used?

The IoT system is considered a revolutionary technology that can radically change and improve many areas of our lives, creating a safer and more convenient environment.


IoT systems in agriculture can perform constant monitoring of precipitation levels, soil conditions, and exposure to chemicals. Special sensors can record waterfalls in the soil and independently activate the irrigation system. In agriculture, the IoT system can provide efficiency, prevent potential risks and reduce costs.


In production processes, IoT systems are also widely used and can ensure safety and improve the quality control process. With the help of built-in sensors, it is possible to automate and speed up complex production processes, manage the inventory process.

“Smart” city

The system can be used to monitor temperature, air humidity, environmental pollution, and predict natural disasters such as earthquakes or floods. Another option for integrating a similar system is the synchronization of street lights and cameras, for example, automatically detecting the presence of people and providing illumination.

These are just a few examples and, despite many challenges, the IoT system is likely to evolve by combining its platform with machine learning and artificial intelligence. It enables us to improve many areas of our life by providing security.
