Assume that a lady wearing a high-tech spectacle walks into her kitchen. The moment she opens the door of her refrigerator, the refrigerator tells her spectacles that there is no more milk. Then, the refrigerator or the spectacles sends a tweet to her husband asking him to pick up a carton of milk on his way home.
When her husband reaches home, his car talks to the garage door which automatically opens. Hurrying in to catch the cricket game on TV, he forgets to lock the car. When he switches on the TV, it notifies him about the unlocked car.
Does it sound like a sci-fi movie to you? Wait for few years and it will become reality.
In the next few years, you’ll most definitely see changes, which will dramatic impact your life.
This is what we call “Internet of Things”
What is Internet of Things?
Internet of Things (IoT) is the network of devices and in general things
that are connected together
and communicating with each other
to perform certain tasks, without requiring human-to-human or human-to-computer interaction.
As we mentioned in the above example, Refrigerator is communicating with Spectacles, Spectacles is sending tweets automatically, Garage talks to Car and opens the gate when Car asks, TV can communicate with Car and send alert that Car is unlocked.
The Refrigerator, Spectacles, Garage and Car are “Things” and this network where everything is connected is called “Internet of Things”.
Another example of Internet of Things:
Imagine for a moment, living in a home where ‘everything’ is connected. As soon as you wake up, your connected bed or pillow tells the TV to switch on so you can watch the morning news. Meanwhile, the coffee maker goes to work, and depending on how well you slept, the machine adjusts how strong your coffee will be. When you get to the shower, the water will be set to the temperature based on how hot or cold the weather is. When you go to your bathroom mirror, it tells you if you need to shave, and reminds you to brush your teeth. When you get to the closet, the mirror helps you pick out your outfit for the day, taking into account when you’re headed too. Then before you head out, a screen or a window on your door reminds you of the things you need to bring, and issues your schedule for the day based on the data in your smartphone or tablet.
This is the future. This is Internet of Things.
History of Internet of Things:
Although the concept wasn't named until 1999, the Internet of Things has been in development for decades.
The first internet connected appliance was a Coke machine at Carnegie Melon University in the early 1980s. The programmers could connect to the machine over the Internet, check the status of the machine and determine whether or not there would be a cold drink awaiting them, should they decide to make the trip down to the machine.
The phrase “Internet of Things” was first coined by technologist Kevin Ashton
way back in 1999, when he used it to describe how data captured by humans would lead to a revolution once computers started generating and collecting data by themselves without any human input.
Since then, the vision of the Internet of Things has evolved due to a convergence of multiple technologies, ranging from wireless communication to the Internet and from embedded systems to micro-electromechanical systems (MEMS).
