Internet of Things: Trends of 2021

The “Internet of Things” (IoT) is a set of buzzwords that are being used increasingly often to talk about digital trends in recent years. In essence, the Internet of Things can refer to anything that is connected to the internet. However, in common discourse, it is most often used to talk about objects that communicate with one another via the internet. Examples include security alarms that send updates to your phone or voice-recognition robots that can control your home’s speakers, lights, and heating.

Much the same as technology, in general, these days, the Internet of Things is moving forward at a rapid pace of development. In just a few short years, the internet has gone from being contained on desktops and services to making its way into a huge proportion of our everyday objects. In fact, at this rate, many envision that it is only a matter of time before just about every object in our daily lives – from our fridge to our toothbrush – is interconnected via the internet.

Being such an increasingly important aspect of both our individual lives and all of society, it’s no wonder that trends in the Internet of Things are a subject of fascination to many. Incredible manpower goes into collecting data to analyze the trends of how people are using and benefiting from objects connected via the internet. All this observation feeds back into further developing smart objects and helps to accelerate the pace of technological development.

Being a rather unique year in which much of people’s lives have been transferred onto the internet, the Internet of Things trends we are witnessing in 2021 is particularly interesting. Internet of things essay examples of past trends, as well as examples about IoT that are specific to this year, give great food for thought when it comes to the way our future will look. Across various areas of technology, these are the biggest trends when it comes to the Internet of Things and IoT devices of the current year.          

Revolutionizing transportation

Over the past years, it has become increasingly apparent of the Internet of Things’ potential to completely overhaul the way we get around. By gathering and analyzing huge sets of data, connected devices can completely change the average travel experience.

Smart, connected devices like self-driving cars are capable of being fed with real-time data from the internet. This means that moment-to-moment, these vehicles are able to make decisions about things like traffic and weather patterns. Furthermore, the more of these devices there are on the road, the more efficient the decisions the devices make become. If every car on the road was able to communicate instantaneously with one another, their collective operating system could use big data analysis to direct the flow of traffic so as to avoid any congestion!

The analysis of large-scale data patterns like this has also led to massive strides forward in transportation safety. The Internet of Things allows researchers, manufacturers, and municipal officials to develop a greater insight into the conditions that are most likely to produce transportation accidents. Big data analysis allows us to identify and mitigate against patterns that we may not have been able to notice before.


The expansion of the Internet of Things means that more and more of our daily objects continue to become connected to the online world. This, of course, means that these IoT devices become susceptible to cyber-theft and hacking. With an estimated 50 billion devices currently making up the network that is the Internet of Things, one must consider that if one point of the network’s security is compromised, it can pose a threat to the entire network.

The hot topic of cybersecurity is something that is routinely addressed in IoT education, with a common assignment being a cybersecurity essay. Papers such as these provide valuable insights on cybersecurity and its importance in the present day. Having more of our lives vulnerable to cyber-crime means that developing and improving cyber-security is at the heart of trends in the IoT, and this year is no exception.

Interconnected devices registered as belonging to one user help when it comes to creating better cyber-security. Multi-factor verification between devices is a simple but powerful tool that most platforms are now using to mitigate hacking and fraud on their IoT devices. Cutting edge computing is also able to use big data analysis to track things like malware and spyware – alerting users before the malware has even reached them.

Connected homes

As has been increasingly the case of the past decade, household items are a major part of how we experience the Internet of Things in our daily life. In 2021, the amount of extra time people have spent in their homes has led to many people investing in connected devices to make their living quarters more efficient and comfortable. In fact, just about half of all Millennials in the USA have at least one smart-home device.

Domestic smart objects include voice-controlled home assistants, smart lighting that responds to time and weather conditions, as well as countless other objects. The interconnectivity of these household objects means that your home is able to learn how to best serve you by analyzing your patterns and communicating with your other devices. This is one area of IoT technology that truly creates a sense of luxury for its users. Imagine a future where your laundry machine prepares your warmest sweater in preparation for a cold day, and your kettle starts boiling itself once you’ve woken up!

The Internet of Things offers humanity an entirely different approach to how we live our lives. There are, of course, those who warn that this kind of interconnectivity leaves us liable to all kinds of dangers we may not even see at present. From very real fears about data mishandling – to more fantastical worries of artificially intelligent robots taking over the world.

It’s unclear as yet exactly how our society will change as more and more of the tools we use become smarter and learn to communicate with one another, but it’s without a doubt that these changes will be revolutionary.
