What Is IOT (Internet Of Things) and How IOT Works?

What Is IOT (Internet Of Things)? – The Internet of Things (IoT) is an important and emerging topic in the field of technology, economics and in society in general. It is referred to as the web of connected devices, made possible from the intersection between machine-to-machine communications and big data analytics.

The IoT is a future-facing development of the internet and abilities of physical devices that are eventually narrowing the gap between the virtual world and the physical world. This section deals with some of the Important IoT concepts which one should be familiar with to understand the advanced topics covered later in this module.

What Is IOT (Internet Of Things)?

Internet of Things (IOT), also known as Internet of Everything (IOE) refers to the network of devices with an IP address that have the capability of sensing, collecting and sending data using embedded sensors, communication hardware and processors.

In IOT, a thing is referred to as the device that is implanted on natural or man made or machine-made objects and having the functionality of communicating over the network.

Internet of Things (IOT), also known as Internet of Everything (IOE) refers to the computing devices that are web-enabled and have the capability of sensing, collecting and sending data using sensors, and the communication hardware and processors that are embedded within the device. In IoT, a thing is referred to as the device that is implanted on natural or man-made or machine-made objects and having the functionality of communicating over the network.

IOT utilizes the existing emerging technology for sensing, networking, and robotics, therefore allowing the user to achieve deeper analysis, automation and intergration within a system.

With the increase in the networking capabilities of machines and everyday appliances used in different sectors like offices, home, industries, transportation, buildings and wearable devices, they open up a world of opportunities for the betterment of business and better customer satisfaction. Some of the important key features of IoT are connectivity, sensors, artificial intelligence, small devices, and active engagement.

How IOT Works?

IoT technology includes three primary systems such as IoT devices, gateway system, data storage system using Cloud and remote control using mobile apps. These systems togethar make the communication between two end points possible.

Disscussed below are some of the important components of IOT technology that play an essential role in the working of an IoT device:

Sensing Technology

Sensors embedded in the devices sense a wide variety of information from their surroundings like temperature, gases, location, working of some industrial machine as well as sensing health data of a patient.

IoT Gateways

Gateways are used to bridge the gap between the IoT device (internal network) and the end user (external network) and thus allowing them to connect and communicate with each other. the data collected by the sensors in IOT devices send the collected data to the concerned user or cloud through the gateway.

Cloud Server/Data Storage

The collected data after travelling through the gateway arrives at the cloud, where it is stored and undergoes data analysis. the processed data is then transmitted to the user where he/she takes certain action based on the information recieved by him/her.

Remote Control Using Mobile App

The end user uses remote controls such as mobile phones, tabs, laptops, etc. installed with a mobile app to monitor, control, retrieve data, and take a specific action on IoT devices from a remote location.

Example:

  1. A smart security system installed in a home will be integrated with the gateway which in turn helps to connect the device to the internet and the cloud infrastructure.
  2. The Data storage at the cloud has the information of each and every device connected to the network. The information possessed includes device’s id, the present status of the device, who all accessed the device and for how many times. it also includes information like how many times. it also includes information like how long the device was accessed last time.
  3. The connection with the cloud server is established through web services.
  4. The user on the other side, who has the required app to access the device remotely on his mobile phone, interacts with it, which in turn makes hime interact with the devices at home. Before accessing the device, he is asked to authenticate himself. if the credentials submitted by him match those saved in the cloud, he gets an access. Otherwise, his access is denied ensuring security. the cloud server identifies the device’s id and sends a request associated with that device using gateways.
  5. The security system that is currently recording the footage at home, if it senses any unusual activity, then it sends an alert to the cloud through the gateway, which matches the device’s id and the user associated with it and finally the end user gets an alert.
