IOT (Internet of Things)

 W h a t   i s   I O T

 The Internet of Things (IOT) describes the network of physical objects - things that are embedded with sensors, software and other technologies for the purpose of connecting and exchanging data.

This devices range from ordinary households to sophisticated industrial tools.

the form of connection – could be through a WIFI

 or Mobile data.)

INTERNET OF THINGS (Devices that have sensors,

 that are programmed to act in a certain way,

 are connected together to achieve a certain result)

 How IOT works

 Here are the 4 fundamental component of IOT

 system , which tells us how IOT works.   

 1.Sensor / Devices

 First Sensors or devices collect data from their

 environment. 

 2.Connectivity

Once the data is collected it is transferred to the

 cloud infrastructure ( also known as IOT

 platform) via Bluetooth,

Wifi , Cellular Network etc.

3.Data processing

 Once the data get to the cloud , software

 performs some kind of processing on it. 

 4.User Interface

   Next , the information is made useful to the end 

– user in some way. This could be via an

 alert to the user (email,text notification etc)     

  Three Layer IOT Architecture

It is a very basic architecture and fulfills the basic idea of IOT.

 1. Perception Layer

     It is known as sensor layer. It has the

      responsibility to identify things and

      collect the information from them.

  2.Network Layer

       Network layer is also known as

       transmission layer. It acts like a bride

       between perception layer and application

       layer.

  3.Application Layer

      Application layer defines all applications

      that use the IOT technology or in which

      IOT has deployed
