I Took an IoT Module… Now I’m Thinking of Moving Back Into a Cave
Understanding the Internet of Things and why connected devices are quietly taking over our world.
Until a few weeks ago, I had only a vague idea what the Internet of Things actually meant. I assumed it was either a broadband upgrade, a complicated Wi-Fi setting, or possibly a new cryptocurrency someone was trying to push on me.
It turns out it’s none of those things.
Instead, the Internet of Things (IoT) is the quietly expanding universe of everyday objects that are connected to the internet and constantly collecting and sharing data.
And once you start noticing it, you realise something slightly unsettling.
They’re everywhere.
The Day I Realised My Watch Was Judging Me
Like most people, I already owned an IoT device without really thinking about it. My smartwatch, for example.
On the surface it’s very helpful. It counts steps, monitors heart rate, and occasionally congratulates me for walking the same distance that I used to cover naturally before I owned a device that reminded me how little I move.
But that watch is part of a much bigger ecosystem.
Today IoT devices include things like:
- Smart watches and fitness trackers
- Doorbell cameras
- Smart heating systems
- Connected cars
- Agricultural sensors in fields
- Traffic management systems in cities
- Industrial machines in factories
In other words, the internet has quietly moved out of the computer and into everything else.
I used to think the internet lived in my laptop.
Now it appears to live in my thermostat, my car, my watch, and possibly even my toaster.
The Scale of the Internet of Things
When I started studying IoT during my course, the numbers got interesting very quickly.
There aren’t a few million of these devices.
There are tens of billions.
Estimates vary depending on the source, but globally we are already well beyond 20 billion connected IoT devices, and the number continues to grow every year.
That means the objects around us are starting to outnumber the people.
Which raises a slightly philosophical question:
At what point do the things in your house become more digitally active than the people living in it?
The Quiet Data Collection Machine
One of the reasons IoT technology is so powerful is that these devices constantly collect data.
Your smartwatch collects health data.
Your car collects driving information.
Your heating system learns your temperature preferences.
Smart meters monitor energy consumption.
Cities track traffic patterns and environmental conditions.
Individually, each device gathers small pieces of information.
Collectively, they create enormous datasets that can be analysed to improve efficiency, reduce waste, optimise systems, and even predict problems before they occur.
In theory, now I say in theory mmmmm, this data can help everything run more smoothly — from farms to factories to entire cities.
At this stage the only appliance in my house not collecting information about me appears to be the toaster.
And I’m not entirely convinced about that.
Why IoT Matters for the Future
Despite the jokes about smart kettles and talking fridges, the Internet of Things is becoming a major part of modern infrastructure.
IoT systems are already helping to:
- Improve energy efficiency in homes and buildings
- Monitor crop conditions in agriculture
- Track patient health in healthcare
- Optimise traffic systems in cities
- Predict equipment failures in industry
In simple terms, IoT allows physical systems to generate data, and data allows systems to become smarter.
And that’s a powerful combination.
Final Thoughts: The Smart Cave Problem
After a few weeks studying the Internet of Things, I’ve come to three conclusions:
- Everything is becoming connected.
- Everything is collecting data.
- Everything is getting smarter.
It’s an extraordinary technological shift, and we’re only at the beginning of it.
Personally, I’m considering moving back into a cave and communicating exclusively through handwritten letters.
Unfortunately, knowing the direction technology is going, someone will probably invent a smart cave with environmental sensors, energy monitoring, and a cloud dashboard.
And at that point, even the cave will be online. Any comments, drop them in down below, would love to hear your thoughts.
