What is IoT? Internet of Things : Explained

Imagine the world where all your devices are being connected to each other be it your car, office or your home. The world where the door opens on its own when it detects a person incoming and locks when detects a stranger. The car lights automatically turn on when it’s in the driveway. What if you can control the household devices with a click on your mobile phone? Well, we have seen all this in science and we have been listening to this more than a decade now. But, guess what it’s no more an imaginary science it’s turning out to be a reality and that is what we call as an Internet of Things(IoT). There are so many applications to IoT which we will cover later in this article.

How IoT Works?

It’s a network of products which are connected to the internet and have their own unique IP address to connect with other devices to automate simple tasks.

How big is IoT?

IoT is much beyond than connecting your laptops and smartphones. IoT is a hub for connecting all your devices at one place. This device will be connected cars, smart homes, wearables, smart cities. According to Gartner report by 2020, there will be nearly 20.6 billion IoT devices connected to different technologies which are a huge number in itself. By 2017 around 40% people who are living in “smart cities” will be in “smart homes”.

History of IoT?

The term Internet of Things (IoT) is 16 years old but the actual idea implementation was done back in the 1970s.Previously this idea was known as “embedded internet” or “pervasive computing“. The term Internet of Things was founded by Kevin Ashton in 1999 during his work. Ashton wanted to seek the attention of senior management and Internet was the hottest term used back in 1999 and it somehow made sense. He gave his presentation the name “Internet of Things”.

How will IoT help us to make our lives easier in future?

As people are getting lazy nowadays and they want automation in everything. So, I think IoT is the best automation thing which would help people achieve their goals easily in near future.

Here are some applications of IoT which will help us in future:

  • Smart Homes, Smart Cities.
  • Connected Cars.
  • IoT in healthcare
  • Agriculture.
  • Energy Engagement.
  • Business Industries.

Now, let’s look into applications of IoT in detail.

Smart Cities

Smart cities are one to the application of IoT which will help solve problems like city pollution, energy shortage, traffic congestion by having better and smarter energy management, automated transportation and reducing pollution.

Basically, by installing the sensor and using the web application it will help people know where to better use their energy and how to save energy because an average man only thinks for 6 mins in a year about energy saving. Also, it will help in guiding about parking slots where can u park your vehicle what are the risks of parking in some restricted area.

By enabling mobile communication it can directly send a message to municipal when a bin needs to be emptied.


You must be wondering how the body can be an application of IoT? But yes it is.

With IoT now you can keep a watch on your baby’s breathing, skin, and baby’s position. You can remember to take your medicines properly at the time which you are comfortable with a wireless chip which provides service which helps people stick to their schedule.

What’s next?

You can also monitor an old aging person by simply having a metered alarm and some few sensors into your house which will start beeping when the person finds any difficulty in their normal schedule.


Due to increasing demand of food government is helping farmers to reach the needs but it’s still a difficult job to fulfill all the needs. That is why agriculture is one the biggest applications of IoT.

With IoT in agriculture now farmers will be able to check data for detecting the soil moisture and nutrients. Proper water supply for plants growth and determining custom fertilizers.


Companies like Samsung and Apple have invested a lot in this technology. But how do they work?

The science is all about IoT, this wearable first collects data with sensors and software and knows about the nature and demands of the user. This data after extracting is being processed to provide better insights to the user and give them a better user experience.

These devices mainly focus on fitness, health, and entertainment.

Energy Management

The power grids are becoming smarter and powerful that it will now analyze data from IoT devices and will better judge the electrical consumers and suppliers which will help improve efficiency.

Smart Grid is the concept behind it.

Here is a small video for you to understand it quickly.

Wrap Up

IoT is the future of technology connected devices and automation. Let me know in the comment section what you think about Internet of Things(IoT).
