While the concept of the IoT has been around for quite a long time, most of the people are still not familiar to it. If you’re also one of them, this comprehensive guide is for you. Covering everything essential you need to know about the Internet of Things, this detailed guide is fabricated to help you learn what IoT actually is, how it , its use cases and advantages, with appropriate real-life .

Let’s get started!

What is the Internet of Things (IoT)?

The Internet of Things, or IoT, is essentially an ecosystem of physical devices, vehicles, appliances, and other things that have the ability to connect, collect and exchange data over a wired and wireless network, with little or no human-to-human or human-to-computer intervention. Allowing integration and data exchange between physical devices and the computer, this new wave of technology focuses on making human life more simplified and comfortable with the right mix of efficiency and productivity.

To be more specific, taking advantage of cutting-edge technologies like Machine Learning, Machine-to-Machine (M2M) Communication and Artificial Intelligence (AI), IoT aims at extending connectivity beyond standard Internet supported physical devices (smartphones, tablets, desktops, and laptops) to a wide spectrum of non-internet-enabled physical devices and everyday objects, such as coffee makers, washing machines, door locks, etc., so you can remotely monitor and control them with the help of a mobile or tablet device.

How Does IoT Work?

Since the mechanism of IoT devices is highly technical, so for many it’s quite confusing how an IoT system actually works. Well, just like any other system has predefined steps and components to make it work, so the Internet of Things has its own. A complete IoT system is made up of four distinct components that work together to deliver the desired output. Let’s look at each component and understand what it does.

How does iot work?

1. Sensors/Devices

First of all, sensors or devices collect very minute data from the surrounding environment. The collected data could be as simple as a geographical location or as complex as health essentials of a patient.

To pick up the most sensitive changes in data, one can bundle multiple sensors together to be a part of a device that is capable of doing more than just sense things. For instance, the mobile phone is a device with several built-in sensors such as GPS, Camera, Accelerometer, without which the phone is not able to sense things.

Thus, be it a standalone sensor or a device having multiple sensors, the first step involves the collection of all the minute details from the surrounding environment.

2. Connectivity

Once the data is collected, it is sent to a cloud infrastructure aka an IoT platform with the help of a medium. That’s where several wireless and wired networking technologies, such as Bluetooth, Wi-Fi, Cellular Networks, LPWAN, Ethernet, etc come into handy. While each of these connectivity options represents a tradeoff between power consumption, connection range, and bandwidth, choosing the best one to transmit data to the cloud solely depends on the complexity level and specific requirements of an IoT application.

3. Data Processing

Once the data gets to the cloud infrastructure, it is stored, analyzed, and processed securely using a Big Data Analytics Engine for better decision making. This analysis can be as simple as checking whether or not the temperature reading on an AC or heater is within an acceptable range, or as complex as identifying intruders in your house with the help of surveillance cameras. The processed data is then used to perform immediate, intelligent actions that turn our ordinary physical devices into exceptionally smart devices.

Data Processing

4. User Interface

The last step involves notifying the end user about the action through an email, text, notification, or alert sound triggered on their IoT application. Depending on the complexity of the IoT system, the user can then either leave the automatically performed action intact, proactively check in on their IOT system, or manually perform an action to backfire or affect the system. For instance, if the user detects some changes in a particular room, he can remotely adjust that room temperature via an IoT app installed on his phone.

6 Benefits of IoT

While the ultimate goal of the Internet of Things is to automate human life to make it more insanely efficient and productive, there are countless benefits of IoT for both businesses and consumers. Mentioned below are just a few of them:

1. Access to High-quality Data

Everyone, especially marketers and entrepreneurs, loves data and with the invention of IoT devices, companies now have greater access to data related their customers and products than ever before. They can take advantage of these real-time operational insights to monitor consumer behavior, deliver better customer experiences and make smarter business decisions. Technically, the more information you have, the easier it is for you to take the right decision.

2. Better Tracking and Management

Whatever the industry is, IoT makes tracking and management a breeze for organizations. From keeping track of inventory item by item to monitoring road traffic and weather conditions to notifying the concerned authorities about any suspicious behavior, IoT revolutionizes the way how we currently track and manage our business assets. In fact, IoT is not just about the smart homes anymore, but it is now also about smart offices, smart warehouse, and smart anything else.

3. Efficient Resource Utilization

Be it home, office, hotel or car, IoT facilitates an efficient utilization of assets for improved productivity. Leveraging the power of machine-to-machine interaction, an IoT system collects real-time data with the help of sensors and actuators so you can further use it to improve process efficiency and minimize human intervention. As a basic example, if any of your Home Appliances notifies you about the task completion, you need not worrying about the inefficient consumption of the electricity.

4. Automation and Control

Automation is the need of the hour and IoT is renowned for the same. Since most of the IoT devices are connected with each other through a wireless infrastructure, they are able to operate on their own with little or no manual intervention. For instance, home appliances such as air conditioner, washing machines, ovens, and refrigerators can be automatically get operated and you can even monitor and control them remotely.

5. Comfort and Convenience

We live in a fast-paced world where busy people don’t even care about small things like switching on/off lights and reading energy meters, and this is where the Internet of Things comes in. The interconnectivity of devices and aggregation of data provides you full control over your all devices that are connected with each other through the IoT system. Since you’re able to control all your devices just through one centralized device like your phone, this leads to greater convenience and comfort.

6. Saves Time and Money

The concept of IoT revolves around getting more done in less time by automating tasks and requiring little to no human intervention. Allowing you to accomplish cumbersome tasks faster and with optimum utilization of energy, IoT not only saves your precious time but also your hard-earned money. For example, if your kitchen electronic appliance has the ability to turn off itself after the task is done, this saves your time and efforts required to manually switch off the appliance as well as extra expenditure caused by the unnecessary use of electricity.
