Internet Of Things (IOT)

INTRODUCTION

It is a matter of fact today that a number of IoT products have surpassed a huge number of humans on this planet.

Approximately there are around 7.62 billion humans on our planet, but to your surprise, by the year 2022 with an increasing graph of IoT devices, there may be around 20 billion IoT smart devices up and running with an increase in the demand of 5g network.

What is the Internet of Things (IoT)?

        The term IoT, or Internet of Things, refers to the collective network of connected devices and the technology that facilitates communication between devices and the cloud, as well as between the devices themselves. 

How does IoT work?

    A typical IoT system works through the real-time collection and exchange of data. An IoT system has three components:

💻Smart devices

  💻IoT application

                   💻A graphical user interface

📞Smart devices:

        This is a device, like a television, security camera, or exercise equipment that has been given computing capabilities. It collects data from its environment, user inputs, or usage patterns and communicates data over the internet to and from its IoT application.

📞IoT application:

        An IoT application is a collection of services and software that integrates data received from various IoT devices. It uses machine learning or artificial intelligence (AI) technology to analyze this data and make informed decisions. These decisions are communicated back to the IoT device and the IoT device then responds intelligently to inputs. 

📞A graphical user interface

        The IoT device or fleet of devices can be managed through a graphical user interface. Common examples include a mobile application or website that can be used to register and control smart devices. 

Examples of IoT devices:

1) Google Home Voice Controller

        Google Home Voice Controller is a smart IoT device which allows the user to enjoy features like media, alarms, lights, thermostats, control the volume and much more functions just by their voice.

2) Amazon Echo Plus Voice Controller

        Amazon Echo Plus voice controller is a popular and reliable IoT device. It is capable to run songs, do phone calls, setting timers and alarms, ask questions, providing information, checking the weather, managing to-do & shopping lists, managing house instruments, and several other things.

3) Amazon Dash Button

Amazon Dash Button is basically a device that gets connected over internet Wi-Fi and makes sure that the user does not lack important household items like soft drinks, grocery material, medical and personal care, kids and any pet items ever again.

If a user wants to fully utilize the Dash Button, then the user must be an Amazon Prime member.

4) August Doorbell Cam

August Doorbell Cam is an effective IoT innovation. August Doorbell Cam allows you to answer your door from anywhere or remote location. It constantly checks your doors and also captures motion changes in your doorstep.

5) August Smart Lock

August Smart Lock has proven to be a reliable security IoT device. It allows the user to manage their doors from any location hassle-free. It helps the user to keep thieves away and family in your home.

6) Kuri Mobile Robot

Kuri is the first sort of home robot and most popular too. It is specifically designed for entertainment. Kuri interacts with the users and captures moments all around the house daily.

7) Belkin WeMo Smart Light Switch

The WeMo Light Switch helps a user to manage your home lights from the wall, your mobile or by using your voice. This smart light switch connects to your existing home Wi-Fi network to give wireless access of your lights – with no subscription or hub required.

8) Footbot Air Quality Monitor

Foobot is a reliable IoT device which is helpful in measuring indoor pollution and leads to improved air quality in houses, workplace, and indoor public spaces. It often gives accurate results.

9)  Flow by Plume Labs Air Pollution Monitor

Flow Air pollution is an amazing discovery in the IoT market. It is a personal air quality tracker which informs the user in which area the air quality is bad and polluted and vice versa. It shows all the results in the map available in its app.

10)  Nest Smoke Alarm

Nest Smoke Alarm is a very useful IoT device. It is a smoke alarm that thinks, speaks and alerts your mobile phone about any un-wanted emergencies in your home. It automatically tests itself.

11) Nest T3021US Learning Thermostat Easy Temperature Control

It helps to control the home’s temperature and cooling environment with no effort from the user for Nest thermostat. It adapts according to your activities and manages room the temperature automatically based on your routine.

12) Philips Hue Bulbs and Lighting System

Philips Hue is a very famous IoT device and is used as a personal wireless lighting system that allows to control your light and create the right ambiance for every moment.

It makes the smart home to live with the most connected lights in the world.

13) Bitdefender BOX IoT Security Solution

Bitdefender Box is a very useful IoT device. It is the Smart Home Cybersecurity Hub that prevents various Internet-connected devices from malware, stolen passwords, identity theft, spying etc.

14) Ring Doorbell

Ring Doorbells is a reliable IoT product and allows the user to answer the door from any place using your smartphone. Protect your home with security cameras from Ring video doorbell.

15) WeMo Insight Smart Plug

WeMo smart plug is a good IoT product which helps to turn on your lights, turn appliances on/off and provides the ability to monitor them from anywhere remotely.

16) Logitech Harmony Universal Remote

Logitech Harmony is a powerful and useful IoT smart device for daily purposes. It is a universal remote which lets you control your house media, lighting, and other smart devices from one location remotely.

17) Particle Photon Wi-Fi with Headers

This is the particles IoT board which provides everything that a user needs to build a connection project. It makes prototyping simple and easy due to plugins.

18) NETGEAR Orbi Ultra-Performance Whole Home Mesh Wi-Fi System

It is an extremely powerful Internet of Things device which maintains the whole-home mesh Wi-Fi system that is capable to cover the whole house with fast WI-FI. It can work with the existing internet service provider.

IoT Life Cycle:

     IoT has a very simple lifecycle of development.

    Deployment followed by monitoring, servicing, managing, which is followed by regular updates and decommissioning at the end.

Advantages Of IoT Devices:

• IoT encourages the interaction between devices called as a machine to machine interaction.
• It provides good automation and control.
• Integrated with more technical information, so it is better to operate.
• IoT possesses strong monitoring feature.
• It saves a lot of time.
• IoT helps to save more money by reducing manual task and time.
• Automating daily life tasks makes good monitoring of devices.
• Increased efficiency and time-saving.
• With good features make a better quality of life.

Disadvantages of IoT Devices: 

• Internet of Things devices does not have any international compatibility standard.
• They may become highly complex resulting in failure.
• Internet of Things devices may get affected by privacy and security breach.
• Reduced safety for users.
• Reduction in the employment of manual tasks thus resulting in job reductions.
• Internet of Things device may take control of life in due course of time with increasing AI technology.

Frequently Asked Questions For The Internet Of Things Devices

    Some of the Frequently Asked Questions for the Internet of Things devices are enlisted below for your reference:

1) What are IoT devices?
