Introduction to Internet of things

What is internet of Things?

Internet of Things is becoming increasingly growing concept that has a potential impact on every one’s life. As name indicates its network of all objects connected and communicated via internet. Internet of things is a computing concept built with the network of physical objects connected to the internet to communicate with other things in their internal or external environment.

IOT is an ecosystem of technologies that monitors the physical device, capture meaningful data and even communicate the data with other devices via IP networks to software applications. All the devices in network will have unique identifier to be able to identify themselves with other devices. Also, each and every object connected in the IOT network has the ability to transfer data over a network even without the requirement of human to human or human to computer interaction.

IOT technologies:

Initially when any object is connected to the IOT network, first it has to be augmented with an Auto-ID technology, referred as RFID tag to make it uniquely identifiable. These RFID tags allow the object to wirelessly communicate information to other devices. In fact, an object also referred as smart object will be embedded with RFID tag and also a sensor. These sensors measure data like capturing fluctuations in the surrounding temperature, changes in quantity, or other types of information. Once these smart objects transfer information, the data moves over IP networks, then gets stored in a central database and finally will be sorted into a human readable format at the destination.

In order to establish communication between the devices and objects, IOT needs few necessary components. Wireless technologies, Micro-Electromechanical systems (MEMS) and the internet are the main aspects responsible for such an intelligent invention. Some of the others include smart objects, RF technologies, central hub of information, and machine to machine communication etc.

Applications of IOT

IOT not only connects with the traditional devices like laptops, desktop computers, smartphones and Tablets but can connect and communicate with any other real world device. Things in IOT refer to wide variety of objects including pets and persons. IOT devices include heart monitoring implants, automobiles with built-in sensors, biochip transponders on farm animals, electric charms and even field operation devices to assist fire-fighters to search and rescue.

All these devices gather all useful information with various technologies and autonomously transfer the information to other devices in the network. Some of the examples wherein IOT is successfully implemented are smart thermostat systems, washers / dryers that use Wi-Fi for remote monitoring etc.

Other examples of IOT include connected security systems, electronic appliances, thermostats, cars, alarm clocks, speaker systems, vending machines, lights in household and commercial environments and more. There are various other applications yet to be applied among which Home automation is one of most awaited concept that implement IOT to control and manage objects in your home via remote assistance.

IOT can connect to anything and communicate with any device, which describes numerous technologies that enable internet to reach out to connect real world physical objects. Once the object is connected to IOT it no longer belongs just to you; but will also be connected to surrounding objects and database data.
