Lets take a simple example of fan, light at your home. To switch it on you should get to the switch next to it (tightly coupled with each other)…
What if you could access them from your mobile maybe you could switch it on from anywhere around the world or it could automatically switch off and on when people stay in the room.
Yes, it is possible with the Internet of things!!!
that was just a basic idea,
Let’s say your armband can detect if there is a possibility of you getting a mild stroke or heart attack.
It could automatically send the analyzed heartbeat data to the hospital nearby so that they can send you an ambulance on time.
Get your operation theatre and all equipment’s required before you reach the hospital.
The concept of Internet of things was found in 1999 by Kevin Ashton
But how actually is this done?
The mantra behind Internet of things !!!!
THINGS + SENSE & COMMUNICATE
We as human beings, we interact and collaborate with other people using sense (hearing, touch, smell, tastes, view)
If the same could have been achieved by things,
Yes, it is possible using sensors. Luckily we have already got a bunch of it.
You will not believe how many sensors your phone has. It can sense, hear, always has an eye on you – smarter than you.
There are 4 steps in IOT – simplified
Sensors play a vital role. The main purpose of the sensor is to communicate with the surrounding environment.
Sensors can hear what you speak, able to find the temperature of a room, humidity, etc.
Devices are the heart piece of Internet of things.
The sensor which is being used should be connected to the devices by any means such as wires or signals.
The most commonly used Devices are Arduino, raspberry pi, mxchips and a lot more.
3.Gateway & protocols
The primary purpose of a gateway is to provide a bridge between different types of communication.
The best example would be the router or modem we have in our home, where it allows us to connect your home to the internet.
The same concept is used in IOT Gateway where it connects your devices through internet or intranet to the cloud
Data moving to the cloud or vice versa goes through the gateway.
Finally, the data from the sensors has reached your database or cloud.
For example, a text alert to your phone when the temperature is too high at home. It is up to you to decide about the UI.
Basically, the entire concept of IoT comes to a point where it can be used effectively and gain control over things or the environment.
The process can be reversed to send instructions to the devices…
If we could use them in a standard way we could find earthquakes and tsunami before it could hit the shores and lots more…
why can’t machines sense when people can?
