Introduction to the Internet of Things (IoT)

This blog aims to provide you with a thorough introduction to IoT. It presents the key ideas of IoT, fundamentals in utilizing and conveying IoT frameworks. Connection between any two computers is called Internet. In this real world any device can be connect with another device is called Interconnection of Things.

IoT (Internet of Things) is an advanced mechanization and examination framework which misuses networking, detecting, big data, and artificial intelligence technology to convey complete systems for a product or service. These frameworks permit more transparency, control, and performance when connected to any industry or framework.

IoT describes a system where items in the physical world, and sensors within or attached to these items, are connected to the Internet via wireless and wired Internet connections. These sensors can use various types of local area connections such as RFID, NFC, Wi-Fi, Bluetooth and Zigbee. Sensors can also have wide area connectivity such as GSM, GPRS, 3G and LTE.


The Internet, is a worldwide system of computer networks – a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers). It was conceived by the Advanced Research Projects Agency (ARPA) of the U.S. Government in 1969 and was first known as the ARPANet. The original aim was to create a network that would allow users of a research computer at one university to “talk to” research computers at other universities. A side benefit of ARPANet’s design was that, because messages could be routed or rerouted in more than one direction, the network could continue to function even if parts of it were destroyed in the event of a military attack or other disasters

What exactly is the Internet of Things?

The Internet of Things (IoT) is such a sweeping concept that it is a challenge to even imagine all the possible ways in which it will affect business, economies and societies. Sensors and actuators embedded in physical objects are linked through wired and wireless networks, often using the same Internet Protocol (IP) that connects the Internet. The Internet of Things will:

  • Connect both inanimate and living things. Early trials and deployments of Internet of Things networks began with connecting industrial equipment. Today, the vision of IoT has expanded to connect everything from industrial equipment to everyday objects. The types of items range from gas turbines to automobiles to utility meters. It can also include living organisms such as plants, farm animals and people. For example, the Cow Tracking Project in Essex uses data collected from radio positioning tags to monitor cows for illness and track behavior in the herd. Wearable computing and digital health devices, such as Nike+ Fuel band and Fitbit, are examples of how people are connecting in the Internet of Things landscape. Cisco has expanded the definition of IoT to the Internet of Everything (IoE), which includes people, places, objects and things. Basically you can attach a sensor to anything and establish connectivity to participate in the new connected ecosystems.
  • Use sensors for data collection. The physical objects that are being connected will possess one or more sensors. Each sensor will monitor a specific condition such as location, vibration, motion and temperature. In IoT, these sensors will connect to each other and to systems that can understand or present information from the sensor’s data feeds. These sensors will provide new information to a company’s systems and to people.

The focus on connected devices and endpoints in the Internet of Things:

The Internet of Things enables the Internet whereby smart devices and other endpoints get connected via Internet technology. The endpoints, ‘things’, physical devices, sensors and controllers are the best known part of the Internet of Things as they are the most visible, certainly in consumer applications. While the devices and things get most attention, the really interesting part starts when we move from devices and connectivity to data, applications, outcomes and actions.

IoT Devices & Products:

IoT platforms for business and custom-made or proprietary tools for specific purposes. Here I have mentioned some IoT devices,

1.Smart Door Locks
2. Smart Bluetooth Trackers
3. Smart Bike Locks & Trackers
4. Smart Home Apps

You immediately see why the Internet of Things is really good and if you’re a beginner or new to the Internet of Things understand why it’s not just a ‘thing’ but really a very diverse reality that covers much more than connected devices.
