As figures compiled by Statista show, the growth of the IoT has been growing for the last few years and is set to skyrocket within the next year or two, with both businesses and consumers adapting smart technology on a massive scale.
You will find more statistics at Statista.
That sounds pretty cool, right? But all this does beg the question of what the Internet of Things actually is, beyond the marketing speak uttered by CEOs and the buzzword of the day on tech blogs.
In this article, Cloudwards.net is going to take a look how the Internet of Things works and whether it’s really going to change our lives the way so many people tell us it is.
We’ll do so by using language that goes light on the technobabble and we’ll include a picture here and there to help you along, as well.
Just in case, we also made a video which goes through some of the most important issues associated with the Internet of Things.

To get started properly, let’s first take a look at what IoT actually is.
What Is the Internet of Things?
In brief, the “things” in Internet of Things are the everyday objects in your house, only hooked up to the internet. It’s really that simple.So think a thermostat that can be controlled from an app on your smartphone (handy on those cold winter mornings) or a coffee maker that switches itself on when it can tell you’ve gotten out of bed.Those two are pretty prosaic examples, but we’re using them because these already exist for people that can afford them: a Dutch energy supplier has launched an app that lets you control the heating in your home from your phone, while there is also a coffee maker that knows when you’re up thanks to its ability to gauge and remember your behavior.More advanced examples that you may end up seeing in your home within the next few years are a fridge that reminds you to get milk when you’re out (or, knowing our audience, when it has expired) by scanning the RFID chips in products or a garage door that opens when it detects you have driven onto your street.There are almost endless examples to pick from when you start looking at IoT projects under development now and all of them have one thing in common: in all cases the devices in your home, at your office and in your pocket are able to “talk” to each other and make limited decisions based off that information.
We say “limited” because they are still just machines, after all. Though we have come a long way since the purely binary decision-making of yesteryear, computers are still, essentially, quite stupid and can only work their way sequentially through a set of problems; we’ll talk about this in depth later on.
With that said, you should have a reasonable idea of what the Internet of Things actually is. Let’s take a look at what it can do.
Applications of the Internet of Things
The benefits of the IoT are first and foremost found in industry. In a way its manufacturing that has led the charge here, as letting machines talk to each other directly rather than through humans has brought about a serious uptick in production across the board. So now some factories basically run themselves, with machines telling each other what they need and when.
Though that specter may make chills run down the spine of union organizers, it’s been positively great for the people that run those businesses, allowing them to turn out more products for a lower cost. The rise of the robots that is going to influence the labor market quite strongly over the next few decades is in large part due to IoT technology.
For regular people the changes are slightly less obvious — except for the resulting unemployment, of course — but we can expect more and more everyday things to be controllable remotely, usually through your phone. After all, why bother with a TV remote when you have a digital device capable of broadcasting over WiFi in your pocket (and hands) all the time?
Since control chips are the size of pinheads these days, almost every imaginable object could become part of the Internet of Things, all you need is to think up a reason why a table or chair should have a chip and all you need to do is build it. The chips are also getting smaller, too, as the machines take over in the factories: right now a form factor (think of it as size) of 10 nanometer is the cutting edge, but Samsung is working on 8nm processes as you read this (note: that’s really frickin’ small).
So, if you think the phone-controlled thermostat and the fridge with a memory are cool, wait till you see self-controlling diabetes pumps that feed you extra insulin when the pantry tells it that you just unwrapped a chocolate bar. How about a store that has no human personnel, yet does all its stock taking perfectly? The possibilities are, to coin a phrase, endless.
Since the elements necessary are so small — and thanks to the revolution in chip manufacturing, not to mention DIY circuit boards like Raspberry Pi so very, very cheap — pretty much anyone can get some parts together and put an IoT device together in their basement. It’s a real sea change in computing and the way we interact with the digital world.
How Does the Internet of Things Work?
Now that we’ve established what the IoT is and the kind of cool stuff you can do with it, let’s take a look at how it works. In essence the Internet of Things is one huge cloud. Though the tiny chip in that coffeemaker is dumb as a rock, thanks to its WiFi connection with a proper computer — or a linked-up system of them — it’s as smart as any supercomputer, allowing it to do its thinking other than in its own brain.
So, imagine you just being you, but next time that you’re faced with a large equation — you never know — you can borrow Stephen Hawking’s brain for a few seconds. Imagine all the things you could do if you had that ability. Be envious of digital devices, because they can do exactly that.
If we stick to the smart coffeemaker in this scenario, that machine has everything you’d expect from one — a glass jug, a filter holder, all that — but also is outfitted with some computer hardware, most likely a small circuit board with a weak processor (technically it’s not a processor, but a SoC), a network card of some kind and, most likely, some kind of sensor that helps it tell if there is already coffee in the pot.
The coffee pot in this scenario is the physical part of the IoT, the one you physically have in your house. On top of comes the cloud, in which all these machines interact with each other. There are also communication protocols in place so your car can’t send messages to your coffee machine and vice versa.
All this is controlled through some kind of control device, most likely an app on your phone or tablet. Ideally this would be one program that gives you an overview of every IoT device you have, but in practice you’ll probably have an app running for each device you own, at least until some whizkid figures out a way to combine them all.
These concepts behind the Internet of Things aren’t too difficult to grasp, but they aren’t what makes the IoT as powerful and impressive as it is. For that, we have to look at what these devices do with the information they collect.
The Internet of Things, Analytics and Machine Learning
As you can imagine, being wired up all the time an IoT device is at risk of experiencing a serious informational overload. Being as dumb as it is, it leaves the thinking up to a cloud of some kind, be it a network of uncountable tiny devices, a big, badass supercomputer or a combination of these.
No matter where all this data is processed, there’s so much of it that the brain of the outfit needs to sort through it all and decide what’s relevant and what isn’t. Your coffee maker can use the information from your alarm clock to know what time you’re getting up in the morning, but knowing that your car is low on gas is of no use to it.
Through a process of analysis, which you’ll often see referred to as “analytics,” an IoT brain can decide what it needs to know and what it doesn’t. This process is often guided by human programmers, but more and more it is also inspired by devices themselves through what is now often called machine learning, but you may also recognize as deep learning.
Machine learning is a type of artificial intelligence that can, you guessed it, learn from its environment and the data fed to it and attach consequences to its choices in a very limited manner. Without machine learning, you’d have to program each and every IoT device by hand for every possible scenario; that’s doable for coffee makers, but impossible for, say, a car.
If you think of the IoT, try and think of it as standing on a tripod: if one leg goes missing, the whole thing falls over. If machine learning is one leg, then the cloud and chip miniaturization technology are the other two.
Risks of the Internet of Things
The threat of Skynet aside, there is a real risk inherent to the Internet of Things. However, it’s not as sexy as your self-driving car trying to kill you and is therefore a little underreported. It centers around the same question that always pops up when large, in this case huge, amounts of data are at stake: namely, what happens to all that information?
By letting an IoT device in your home, you’re basically installing a bug, one that can gather data from other digital devices, maybe even hear and see you. This isn’t that bad in and of itself, it needs to fulfill its purpose after all, but what happens with the data it gathers?
This question reared its ugly head during the United States Senate debate about ISPs being allowed to spy on their customers and the fact is, all this data is out there: the more IoT devices you have in your home, the bigger the chances are that certain data regarding your life is recorded somewhere. If someone has seen it is a second concern, but it does exist.
In fact, certain IoT gurus have touted this data gathering as a major plus to the Internet of Things for marketers and the like, as by knowing your habits, it will be easier to target ads at you. If you’re even remotely concerned about your privacy, this will likely be a terrifying thought.
After all, when you boil it all down, we all have something to hide somewhere and it’s going to be all the easier to find by having all that data floating around. On the flipside of that, how will it affect your behavior if you know you’re being spied on all the time, and by the devices you paid for with your own money? Will you still be able to lead the life you’ve always wanted?
Final Thoughts
The Internet of Things is a truly amazing development that is likely going to change our lives for the better: it’s already bringing about massive positive changes in industry, healthcare, logistics and our own homes. However, as with all such developments, there is a darker side that we need to deal with as well.
Thing is, when it comes to digital security, the white hats are always going to be a step behind the black hats: the only proof you need is the recent WannaCry ransomware attack that put several corporations as well as governments out of business for a few hours.
Imagine that had happened to every single device you own: your coffee maker would not pour a pot unless you paid some cybercriminal a couple of bucks and your car wouldn’t start until you purged its memory of a few viruses.
Though the Internet of Things is a wonderful development that will bring a lot of improvement to both our lives as well as the way business is conducted, the risks associated with it should not be ignored or downplayed.
Whether it’s unemployment due to automation or even more of your personal data being hawked on the open market or simply criminals being able to mess with more facets of your life, the IoT is not something consumers should embrace blindly without knowing about all the risks.
