If you look around, you’ll find at least one thing that has the ability to connect to the internet. It may be your phone or maybe a laptop, your TV, or even your fridge, internet of things generally refers to the collection of all those devices. But now just, you can argue that anything that has the ability to connect to the internet and collect and share data is a part of the internet of things or IoT in short.

what is IoT?
So just as we discussed IOT is the collection of all those devices that have the ability to connect to the internet and collect and share data. Hence the name internet of things. So basically we have a device that collects data from its surroundings, using sensors and actuators, and sends this collected data to the internet where the processing of that data can happen.
There are many devices that can be included in this classification. An example can be phone laptops, watches, DVS refrigerators, washing machines. Cars and even homes. Yes. Whole homes themselves can be a part of IoT too. Most IoT devices have the word smart at the start of their names, smartphones, smartwatches, smart DVS, smart refrigerators, and smart homes.
So now that we have a clear idea of what IoT is, we can move to the next question.
Why do we need IoT? Or how does it help us in short?
It helps make our lives. Easier and more comfortable.
If we take an example, we had listed earlier, like smartphones, smartphones have more use cases than I can, you know, list here without going on for ours and ours, it can call, it allows us to watch movies. It allows us to connect to the internet, interact with strangers on veered forums shop or things. We need general entertainment. You get the idea, but let’s take a better example for our understanding.
A smart house has many different features that we can talk about. One of the features is automatic lights, where the lights automatically detect your presence in the room and get switched on, or they can be voice-activated. You can say activate and they’ll get searched, John. And it also has his name next-gen security to keep your house safe, but it allows only authorized people to enter your and locks up everything.
When you leave. Then it has entertainment management, fair using devices, such as Google Home, Alexa echo to keep track of your chores, to play movies and songs, etc. It also keeps track of temperature management, the house automatically adjusts to the most, you know, temporary too, based on the surrounding climate.
So you can see how it brings luxury into our lives and makes it more comfortable for us to live. Now, this is at an individual level, at a larger scale. It benefits society as a whole too in industries. Such as healthcare, it has many use cases, doctor, patient interaction, for example, it allows for remote interaction between patients and doctors. So if a patient has any sort of a deadly disease, the doctor doesn’t necessarily have to come in close contact to help the patient out.
IoT in medical and healthcare
Another example here is that data analysis is improved greatly. Now doctors make amazing decisions and based on the time and the data they’ve been given, but computers can sometimes make better decisions. And combining doctors and computers can give us the best diagnosis possible. Follow the patient. So it helps us out a lot in the healthcare industry. Farming, not farming has been one of the industries that have stayed with us since the beginning of human civilization itself.
And right now is the correct time to improve upon our traditional methods and shift into modern farming to provide food for our evergreen population. Smart technologies have definitely helped us increase productivity through new devices like smart trackers and analysis devices. That will help us to get a better data analysis of soil, then gums, manufacturing industry.
Now this industry has already taken IoT with open arms. It already has automation replacing many menial jobs. I already even not only increase the interactivity but also boost efficiency, add production as well. In this industry then comes the education industry. Now better methods to teach children are already being implemented out there that are in conjunction with IoT.
A good example is augmented reality. Being used in some classes to give students a better experience of real-life animals, and even extinct animals. Hence having IOT will not only be beneficial to us individually but also be beneficial to us as a society. Then comes the next question.
How does IOT work?
Let’s discuss IoT architecture.
There are basically four layers to it.
- Sensing the Slash Device
The first layer is sensing the slash device there, which is basically the thing part of IoT. This thing is basically the, with the device. It has sensors and actuators that collect the data from surroundings based on specific functions. Examples, preachers, sensors, atmospheric pressure sensors, and light sensors. They basically collect all the data and they give it to the embedded.
- Connectivity Layer
The device now after the data has been collected through the sensing device layer, it goes to the connectivity layer, very descent to the cloud. Using the internet.
This connection is generally me through one of the methods like via
Bluetooth cellular, RFID, or NFC.
- Data Processing layer.
After that comes to the data processing layer. Now the data, once it reaches the cloud is subject to the real meat of the whole process. That is the analysis part of the data.
The different types of algorithms are used. Based on the type of data collected and other assumptions to get meaningful insights and patterns, then a decision is made based on the insights gained. Once the hard part is over the result of the decision is conveyed
to the thing or the IoT device.
- Interface The last Layer
Similarly changes made user interface and application. Yeah, it’s the last layer. This is a layer that most of us will actually see. It is a layer we used to with the dietary device. It can be the touch screen or the buttons that are on the device. It’s basically the front end to all the back end processing, which included the previous level.
Example explaining IOT
Now a good example to explain
This process, let’s say a fridge, a smart fridge. Now sensors in the smart fridge, collect data from the surrounding. They see what kind of temperature it is. Let’s say it’s 34 degrees.
And what kind of item is being stored inside the fridge? Once it collects all of this data, it sends it to a central cloud where the processing happens based on this collected data. The system decides the inside temperature of the fridge. It should be 20 degrees and we can see the result of this on the interactive screen, on the fridge. Now we had no involvement in this process, but we saw the result that we wanted. This is how IoT works in adjust.
What kind of feature does IOT have?
It would not be crazy to see that we may live in the future. Heart Lake Howard is depicted in sci-fiction movies, not the star or Skype, but more like the blatant and Ironman kind. But everything we touch on, everything
we used is connected to the internet, buried with central cloud, where all of our data is being collected and being utilized to make a lie, Anna society a much better place.
You can assume almost everything is going to be automated and connected to the internet, everything, your table, your phones, which are already are your
doors, your hangers, you know, examples. And you can see that all of them are going to be a part of IRD in the future.
And there is definitely much space for growth. So if you’re thinking of a career in this field, not at all a bad idea, it will be both satisfying and challenging. And it will be used to make our lives easier. Every person, no problem what background or what profession they are from will be affected by it in both good and bad ways, it will be, or rather it is the advent
