The Internet of Things (IoT) is a network of physical objects that are embedded with sensors, software, and network connectivity to collect and exchange data. These objects are referred to as IoT devices or connected devices. For example, an IoT device in your car can identify the traffic ahead and send out a message automatically to the person you are about to meet of your impending delay.
The IoT is rapidly growing, with billions of devices now connected to the internet. This growth is being driven by the increasing availability of low-cost sensors and connectivity, as well as the growing demand for more connected devices in our homes, businesses, and cities.
As of 2021, there were 21.7 billion active connected devices in the world today, out of which more than 11.7 billion (54 percent) are IoT devices.
In this blog, we will delve into the world of IoT.
What is IoT ?
The internet of things, or IoT, is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
A thing in the internet of things can be a person with a heart monitor implant, a farm animal with a biochip transponder, an automobile that has built-in sensors to alert the driver when tire pressure is low or any other natural or man-made object that can be assigned an Internet Protocol (IP) address and is able to transfer data over a network.
How does IoT work?
An IoT ecosystem consists of web-enabled smart devices that use embedded systems, such as processors, sensors and communication hardware, to collect, send and act on data they acquire from their environments. IoT devices share the sensor data they collect by connecting to an IoT gateway or other edge device where data is either sent to the cloud to be analyzed or analyzed locally. Sometimes, these devices communicate with other related devices and act on the information they get from one another. The devices do most of the work without human intervention, although people can interact with the devices -- for instance, to set them up, give them instructions or access the data.
Types of IoT
The networking, communication and connectivity protocols depend largely on the specific IoT application deployed. Just as there are many different IoT devices, there are many types of IoT applications based on their usage. Here are some of the most common ones:
Consumer IoT - Primarily for everyday use. Eg: home appliances, voice assistance, and light fixtures.
Commercial IoT - Primarily used in the healthcare and transport industries. Eg: smart pacemakers and monitoring systems.
Military Things (IoMT) - Primarily used for the application of IoT technologies in the military field. Eg: surveillance robots and human-wearable biometrics for combat.
Industrial Internet of Things (IIoT) - Primarily used with industrial applications, such as in the manufacturing and energy sectors. Eg: Digital control systems, smart agriculture and industrial big data.
Infrastructure IoT - Primarily used for connectivity in smart cities. Eg: infrastructure sensors and management systems.
Importance of IoT
As IoT grows exponentially year on year, companies are leveraging the tremendous business values it can offer. Here are some of the most important benefits of IoT:
- To generate new business models and revenue streams
- To improve business decisions through data-driven insights from IoT data
- To increase productivity and efficiency of business operations
- To enhance customer experience
Although the worldwide spending on IoT has been significantly impacted by the economic effects of the COVID-19 pandemic, a study by IDC shows that it will achieve a CAGR of 11.3 percent over the 2020-2024 forecast period.
The Future of IoT
Looking ahead, the Internet of Things shows no signs of slowing down. As technology advances, the number of connected devices will continue to skyrocket, creating a more interconnected world. The integration of artificial intelligence and machine learning will enable IoT devices to make smarter decisions, analyze vast amounts of data in real-time, and adapt to user preferences.
5G networks will play a pivotal role in supporting the growth of IoT, providing faster and more reliable connectivity. Edge computing.
Here are some of the most promising IoT trends for the future:
The growth of smart cities: Smart cities are using IoT devices to collect data about traffic, pollution, and other aspects of city life. This data can be used to improve the efficiency of city services and to make cities more livable.
The rise of the Internet of Everything: The Internet of Everything (IoE) is the next generation of the IoT. The IoE will connect not only physical objects, but also people, data, and processes. This will create new opportunities for businesses and organizations to innovate and improve their operations.
The development of new IoT applications: The IoT is still in its early stages, and there are many new applications that are still being developed. Some of the most promising new applications include
- IoT-based healthcare: IoT devices can be used to monitor patients' health remotely, which can help to improve patient care and reduce costs.
- IoT-based transportation: IoT devices can be used to track the location of vehicles and optimize traffic flow. This can help to reduce congestion and improve air quality.
- IoT-based agriculture: IoT devices can be used to monitor crops and livestock, which can help to improve yields and productivity.
The IoT is a rapidly growing technology that has the potential to change our world in many ways. It is important to be aware of the benefits and challenges of the IoT, and to take steps to mitigate the challenges. With careful planning and execution, the IoT can be a force for good in the world.
