What you need to know about IoT

Imagine you leave your house and suddenly realize you forgot to turn off a major appliance or left some lights on. With the power of the Internet of Things however, your nerves are instantly calmed because with the single click of your phone you can control any IoT enable device in this day and age. In this article, we will talk about what the Internet of Things means, and different aspects you should care about within IoT to provide you a perfect guide.

Introduction

As we charge closer toward the Fourth Industrial Revolution, there are an estimated 36 billion interconnected devices installed worldwide as of the year 2021. Almost every one of these devices is connected to the internet with the help of the Internet of Things, and devices that are not connected nowadays will be connected with one another in near future. The Internet of Things, or IoT, is primed to be the source of the next industrial revolution. Analysts and technologists predict this technology is going to transform not only our lifestyle, but will also bring changes in technology as well. So let’s find out what actually the IoT is and why it is necessary.

What is IoT?

How big is the IoT and how fast is it growing? The number of connected things, from computers to household monitors to cars, is projected to grow at an annual compound rate of 23.1% between 2014 to 2020, reaching 50.1 billion things in 2020. - Gil Press, Forbes.

Internet of Things, or 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 with other devices and systems on the internet. IoT is also defined as the system of interrelating computing devices that are provided with UIDS or unique identifiers so they can transfer and store data without any human assistance. Electronic devices are usually connected with the help of different sensors, software, and other technologies, and this system operates with the help of the internet. According to a survey published by Forbes, nearly 60% of organizations in 2016 took initiatives to invest in IoT, and one can only imagine how this process has multiplied in recent times.

How IoT Works

The Internet of Things has become part of our lives, and whether consciously or unconsciously, we are all using it. For example, you are possibly reading this article on your device that is connected to the internet. Consider your device and all of the different kinds of sensors and software powering them. These are used to collect and transfer data such as location, images, and locations, and then convert said data into practical application in real-time.

IoT devices can be categorized into two ways

  • General IoT devices
  • Sensing IoT devices

General IoT devices are considered the main component of a data hub, and are connected through either wireless or wired interfaces. For example, home appliances usually are related to this category. On the other hand, sensing IoT devices are sensors and activators that measure factors such as temperature, pressure, humidity and other telemetric data. Both of these devices make the connection with the help of gateways that process information and transfer data to the cloud. Once collected, final actions are performed on this data and inferences, and the connection is facilitated by different devices such as WIFI devices, etc. For example; You want to check your room temperature on a regular basis. Instead of the old way of using a thermometer, nowadays with the help of your internet connect thermostat you can check the temperature and manipulate it with the help of an IoT gateway. This data is stored in the Cloud and can be used for convenient things such as trend analysis, cost reduction, gains in efficiencies, and more. This is the way by which IoT is reducing the burden of human beings in different industries.

Benefits of IoT

Increase in efficiency of resource utilization

Across many industries, businesses are reducing costs and increasing efficiencies via the deployment and collection of IoT sensor data. Logistics companies deploy sensors in delivery vehicles to track fuel economy, engine maintenance, driver utilization, and more. In the home, consumers install smart devices to save costs on heating and power bills. All these use cases contribute to a reduction of resource utilization. In essence, IoT is a green technology.

Save precious time

As we know, time is money and we can save time by using IOT as well. For example, in the previous example the time businesses used to spend manually tracking logistics data has been reclaimed. IOT can help us save our time with efficient work within a short duration.

Fewer burdens on human beings

IoT reduces the burden on human beings by providing results with less effort. For example, instead of manually checking the temperature outside every day, you can simply get all the climate data you want with a single click. Similarly, due to human nature, data can only be as good as the process which collects it, which can introduce errors. However IoT can eliminate the human error component in data collection.

Security

IoT sensors can be used to provide physical security in public or private places. Many IoT enabled door notification systems provide motion-captu

re enabled video surveillance in millions of homes across the world. Businesses use IoT enabled security cameras to track suspicious cu

stomer or employee behavior, resulting in reduced theft of goods and services.

Easy to use

IoT is very user-friendly. A common layman can easily use it to monitor activities. For example, if you need to track the temperature of a particular area, IoT can send reports that you can easily read without any technical jargon.

Disadvantages

Privacy

IoT can seriously affect personal privacy. For example, a person using a device that may be malicious can experience a severely compromised digital identity. Sometimes devices contain sensors that can continuously share data without permission, which is also a possible disadvantage of using IoT.

Complexity

Installing and setting up IoT devices for the first time can be complicated, and in the case of any error you encounter, you run the risk of improperly deploying the device. Similarly, internet, software, and hardware-related problems can be complex sometimes for the non-technical individual which can lead to improper deployment or security vulnerabilities (E.G. default passwords, config, etc.).

The dangers of unemployment

Some human-based jobs are in danger of being augmented with IoT devices, and down the road in the future this can increase the unemployment rates. For example, instead of hiring a person to regularly track telemetric data, a business can save money by deploying IoT sensors to collect and aggregate automatically. This will also reduce job opportunities.
