What is the Internet of Things?

The Internet of Things, or IoT, is a comprehensive system of interconnected devices, machines, animals, people, and objects with unique identification codes (UIDs) and the capability to transmit data over a network without needing human-to-human or human-to-computer interaction.

Thanks to the diligent efforts of technicians who began adding sensors and processors to objects in the 1990s, we can now connect and automate all kinds of things. However, the process was initially slow, as the required chips were large and expensive. Initially, RFID tags were valuable equipment, but as technology evolved, these chips became smaller, faster, and more intelligent.

In the Internet of Things, an object could be anything, ranging from a toothbrush to a cow with a chip or a car with built-in sensors that alert the driver when tyre pressure is low. In essence, anything that can be assigned an Internet Protocol (IP) address and transmit data over a network can be considered a "thing" in IoT.

Moreover, it's worth noting that even humans could join the Internet of Things if we had chips implanted in our bodies to transmit data over a network. This could potentially revolutionise how we interact with technology and the world around us, but it raises ethical concerns regarding privacy and security. Nevertheless, the possibilities of IoT are vast and continue to expand as technology advances.

How does the Internet of Things work?

The fundamental concept behind the Internet of Things (IoT) involves linking everyday objects to the Internet through processors and sensors. These sensors can gather data on environmental and usage variables such as temperature, movement, and utilisation. This data is then conveyed to a central system through a wireless connection like Bluetooth or Wi-Fi.

Subsequently, the central system processes and evaluates the incoming data with software designed to function with IoT. This software can conduct automated functions, such as illuminating or extinguishing lights or transmitting notifications to a mobile phone.

Moreover, the central system can be integrated with other systems, including the Internet and other networked devices, thus enabling data interchange and application integration.

IoT can unify and automate various objects, resulting in many benefits, such as enhanced efficiency, saved time, augmented safety, and improved decision-making capabilities. As technology continues to evolve, the potential applications of IoT are boundless and may significantly transform how we interact with the world around us.

IoT components

An IoT system operates through the real-time collection and exchange of data. In essence, this system comprises three main elements:

Smart Devices

Any object that connects to the Internet, such as a television, security camera, vehicle, baby monitor, or kitchen appliance, can be integrated into an IoT network. A given device gathers data on its surroundings, user interactions, or usage trends and transmits it via the Internet.

IoT Application

An IoT application comprises a set of services and software that combine data from various IoT devices. This data is analysed with machine learning or artificial intelligence (AI) algorithms to generate well-informed decisions. The IoT device then responds intelligently to the inputs fed back to the device.

Graphical User Interface (GUI)

An IoT device, or even an entire network, can be managed through a user-friendly GUI. This interface can take various forms, such as a mobile app, website, or hybrid app, enabling users to register and control smart devices.

Why is IoT important?

The Internet of Things (IoT) is significant as it connects various devices, machines, and sensors to the Internet, allowing them to communicate. This enables companies and organisations to work more efficiently, enhances data collection and analysis, and accelerates decision-making. Furthermore, it can improve the quality of life by creating smart homes and enhancing healthcare services.

IoT allows companies to automate processes and decrease labour costs, reduce waste and improve services, make the production and delivery of goods more affordable, and provide transparency in customer transactions.

IoT is one of the most crucial daily technologies, and its usage will continue to expand as more companies recognise the potential of connected devices to maintain their competitiveness.

IoT Applications and Examples

Let's look at some examples of IoT systems used today.

Smart Home

Starting with the most common use of IoT currently: smart homes. IoT makes it possible to create homes that can be remotely controlled and adjusted. For example, a smart thermostat can be operated via an app to automatically adjust the temperature in the house based on your preferences and outside temperature. It is also possible to remotely control lighting, security, and entertainment systems.

Healthcare

IoT technology can be used to monitor and improve people's health. For example, wearable devices like smartwatches can collect data about a person's activities, such as heart rate, blood pressure, or sleep quality. This data can be shared with a doctor or nurse. Sensors can also be placed in the homes of older people to monitor whether they are behaving normally and whether they need help.

Transportation

IoT can even be used to improve transportation. This can be done through smart traffic lights that adjust depending on traffic intensity to keep traffic flowing smoothly. Vehicles can also be equipped with sensors that collect data about their performance, which can be shared with the manufacturer or carrier. This can contribute to a more efficient and safer transportation infrastructure. 

Education

An example of how the Internet of Things can be used in schools is by implementing smart classrooms. This can be done by installing classroom sensors that collect data on student attendance, temperature, humidity, and light levels. This data can then be shared with teachers and the school board, who can use it to optimise the learning environment. If the sensors indicate the humidity is too low, the humidifier can be turned on automatically. Or if the sensors indicate that consistently too few classrooms are available, the board may decide to build additional classrooms.

In addition, it can also increase safety at school. Smart cameras can be installed to monitor the school grounds, and access to buildings can be managed through an access control system linked to a smartphone app or smart card. This technology can also facilitate direct communication between teachers, parents, and the school board.

Businesses

The versatility of IoT technology means it can be applied to a wide range of industries, from business-to-business (B2B) to business-to-consumer (B2C). By improving efficiency, productivity, and customer experience, IoT transforms how companies operate and interact with their clients.

IoT technology allows for creating smart factories using sensors on machines and production equipment to collect data on their performance and condition. This data can be stored within databases to be used later or shared in real-time with relevant parties, including management, to increase productivity, plan maintenance, and quickly solve problems. For instance, if sensors detect that a machine is overheating, the company can perform maintenance promptly to prevent the machine from shutting down.

In addition, IoT technology can also be used to improve a company's logistics by tracking the location and status of trucks, ships, or aeroplanes using GPS sensors. This can help businesses increase efficiency and reduce costs.

Another example is the use of IoT in the retail industry, such as in a supermarket where sensors are placed in the store to monitor how many products have been sold, which products are running low, and which products are often purchased together. Based on this information, stores can better manage their inventory, adjust their product range, and offer personalised to customers.
