What is the Internet of Things?

The title that would best describe the concept of IoT (Internet of Things) would be: “Everything connected!”. Almost any physical object can be converted to an IoT device, if it can be connected to the Internet to control or communicate information. Connecting all these different objects and adding sensors to them adds a level of digital intelligence to devices, allowing them to communicate data in real time.

The most important? With the IoT platform, each connected object acquires its digital existence. Collecting data from them allows us to gather information, make timely decisions, automate processes, and more. Gradually, we can integrate networked objects into Artificial Intelligence and Machine Learning Systems. Thus, information becomes catalysts for continuous improvement and maximization of efficiency and adequacy of resources in the production process.

A light bulb that can be turned on via a smartphone app is an IoT device, as well as a motion sensor or smart thermostat in your office or a connected traffic light, an electronic precision screwdriver, or even an irrigation system in a field. On an even larger scale, sensors are being placed in smart city projects to help us understand and control the environment. The Internet of Things makes our surroundings smart and interactive, connecting the digital with the physical world.

How big is the Internet of Things?

Big enough and constantly growing – there are already more connected things than people in the world. Technology analyst IDC predicts that there will be a total of 41.6 billion connected IoT devices or “things” by 2025. It also suggests that industrial and automotive equipment represents the greatest opportunity for connected “things”, but also sees strong adoption of smart home and mobile devices in the near future.

Below you can see its most common applications and some more innovative ones!

Industry (IIoT, Industrial Internet of Things)

The IIoT scope covers a wide range of connected “things” both inside and outside the factory. For example, IoT projects include holistic intelligent factory solutions with many elements such as production monitoring, use of wearables and Augmented Reality, remote PLC control or automated quality control systems. “Outdoor” projects are the remote control of connected machines, equipment monitoring or the management and control of entire remote industrial facilities such as oil rigs.


Typical applications include telematics and fleet management solutions connected to the in-car operating system for vehicle diagnostics / monitoring, such as battery monitoring, tire pressure monitoring, driver monitoring or simply vehicle monitoring.


The majority of projects focus on power distribution, network optimization, remote asset monitoring and management, forecasting and creating more transparency for better informed customers.


More and more retailers are recognizing that they can improve their cost-effectiveness and in-store customer experience through innovative IoT use cases. There is a growing industry interest in digitizing stores and creating smart processes. Typical IoT retail solutions include in-store digital signage, customer tracking, merchandise tracking, inventory management, and smart vending machines.


Smart cities are thriving and flourishing in all parts of the world. The IMD Smart City Index ranked Singapore, Zurich and Oslo as the 3 smartest cities in 2019, followed by Geneva, Copenhagen, Auckland, Taipei, Helsinki, Bilbao and Dusseldorf, finishing in the top 10. Typical IoT projects in Smart Cities include connected traffic (smart parking, traffic management), utilities (smart waste, lighting), public safety (CCTV, Facial Recognition) and environmental monitoring (air pollution).

Health Sector

The IoT has spread slowly in healthcare. However, things seem to be changing in the light of the COVID-19 pandemic. Preliminary data show that COVID-19-related digital health solutions are on the rise. Demand for specific IoT health applications such as telematics, digital diagnostics, remote monitoring and robot assistance is growing. Typical IoT healthcare projects in hospitals / clinics include medical device monitoring, health team coordination, workflow optimization, and outpatient solutions include patient monitoring, assisted living, geriatric care, and medication management.

Supply chain

As supply chains become more and more end-to-end, resulting in more complex flows of goods that are more complex in delivery, logistics providers are increasingly integrating connected digital solutions to address complexity. Typical IoT projects in the supply chain include asset monitoring, condition monitoring (eg refrigeration chain, medical supplies), inventory management, automated guided vehicles, connected workers.

The Covid-19 pandemic highlighted the value of IoT monitoring throughout the supply chain. Unfortunately, recent months have shown the volatile reality that even vital medical equipment can be depleted as global supply chains are disrupted. This awareness is expected to be a great guide to IoT solutions in the supply chain to help companies stay in control and respond quickly to challenges.


By 2050, it is estimated that a population of nearly 10 billion people will need up to 70 percent more food than today. One way to meet this challenge is through smart farming. IoT sensors can help farmers make more informed decisions to achieve higher crop yields, better quality products and cost savings by reducing the use of fertilizers and pesticides.

Smart farming projects include precision agriculture, animal monitoring, irrigation management and automated farm tracking, field mapping, crop spraying, etc. The analysis of case studies suggests that innovative technologies such as LPWAN pave the way for the development of Smart Agriculture in the Internet of Things landscape. LPWAN provides a number of features in terms of power consumption and long range, ie the main network requirements for key applications in the field.

LPWANs are ideal for collecting data on local agricultural conditions such as weather, soil moisture, soil chemical composition and other environmental conditions at a much lower overall cost. In addition, LPWANs make it possible to extend coverage per acre and track more assets due to the simplicity of development and cost reduction.


Connected Building projects include installation – automation and monitoring for building systems (HVAC, lighting, elevators, smoke alarms, fire extinguishers), use and security of buildings (room use, access, surveillance).
