What is Internet Of Things (IoT)? And how does it work?

The internet of things, or IoT, is a network of connected computers, mechanical and digital machines, objects, animals, and even people. Each of these things has a unique identifier (UID) and can send and receive data over a network without the need for human or computer interaction.

A thing in the internet of things can be a person with a heart monitor implant, a farm animal with a biochip transponder, a car with built-in sensors that tell the driver when the tyre pressure is low, or any other natural or man-made object that can be given an Internet Protocol (IP) address and can send and receive data over a network.

IoT is being used more and more by businesses in a wide range of industries to run more efficiently, learn more about their customers to provide better customer service, make better decisions, and increase the value of their business.

How does IOT Work?

An IoT ecosystem is made up of smart devices that can connect to the internet and use embedded systems like processors, sensors, and communication hardware to collect, send, and act on data they get from their environments. IoT devices share the sensor data they collect by connecting to an IoT gateway or other edge device. From there, the data is either sent to the cloud to be analysed or is analysed locally. Sometimes, these devices talk to each other and act based on the information they get from each other. Most of the work is done by the devices without human help, but people can set them up, give them instructions, or access the data.

Why does IoT matter?

People can live and work smarter and have more control over their lives with the help of the internet of things. IoT is important for business, and it also has smart devices that can be used to automate homes. IoT gives businesses a real-time look at how their systems really work, giving them information about everything from how machines work to how the supply chain and logistics work.

IoT lets businesses automate tasks and cut down on labour costs. It also cuts down on waste and improves service delivery, which makes it cheaper to make and ship goods and gives customers more information about their transactions.

IoT is one of the most important technologies in everyday life, and it will continue to grow as more businesses realise how connected devices can help them stay competitive.

Internet of Things (IoT) benefits and drawbacks

Some of the pros of the Internet of Things are:

  • access to information from anywhere, at any time, on any device.
  • better communication between electronic devices that are connected.
  • saving time and money by sending data packets over a network that is already connected.
  • By automating tasks, a business can improve the quality of its services and reduce the amount of work that needs to be done by humans.

Some problems with IoT include:

  • As the number of connected devices grows and more information is shared between them, hackers will have more chances to steal private information.
  • Enterprises may have to deal with tens of thousands or even millions of IoT devices in the future. It will be hard to collect and manage the data from all of these devices.
  • If there is a bug in the system, it is likely that every connected device will become corrupted.
  • There isn’t an international standard for IoT compatibility, so it’s hard for devices made by different companies to communicate to each other.

Top IoT frameworks

Google’s Brillo/Weave

is a platform that makes it easy to get IoT apps up and running quickly. The platform is made up of two main parts: Brillo, an Android-based operating system for developing low-power embedded devices, and Weave, an IoT-focused communication protocol that allows the device to communicate to the cloud.

Best IOT Real-world applications

The internet of things has several real-world applications, including consumer IoT, enterprise IoT, and manufacturing and industrial IoT. (IIoT). In addition to automotive, telecommunications, and energy, the Internet of Things (IoT) has applications in many other fields as well.

1. Agriculture and Pest Control

Since we’re looking at IoT applications and use cases, let’s start with farming. Agriculture is crucial for human survival, but the growing population makes it difficult to continue large-scale farming without a big revolution.

IoT applications in agricultural can help enhance production and keep up with the global population boom. IoT applications can result in precision farming, using analytical data to understand soil moisture level, climate fluctuations, plant requirements, etc., to enhance production and encourage efficient use of resources.

2. Environment

We’re growing more mindful of the environment and human-caused destruction. We’re slowly correcting our faults and addressing environmental challenges. We can do this with IoT apps.

IoT helps save bees. Honey Pollution endangers bees. They’re affected by climate change. Beekeepers can better preserve hives with IoT devices. Using IoT and connected sensors, beekeepers can monitor hive temperature, food levels, and pollen harvest. IoT can be utilised in trash management to improve the environment.

3. Smart Home Applications

Smart homes are likely the most common use case for the Internet of Things. The internet has been at the centre of the idea of smart homes for a long time. Many people thought that their dream of having a smart home could actually come true.

IoT applications are used in a smart home to make it work. Smart home devices collect information and share it with each other through an integrated platform. They also take actions automatically based on what the owner wants. So, it’s clear that they go through a learning process to figure out what their owner likes.

Smart home appliances have a lot of IoT use cases, but one of them can be Smart Thermostats, which monitor and control the temperature of a home to make the owner feel comfortable. There is also “smart lighting,” in which the lights change themselves based on the user’s preferences and the lighting outside.

4.Safe Driving

Car accidents have become more tragic as the number of people who use cell phones has grown. Distracted driving has been linked to these wrecks. Even though people have been told not to use cell phones while driving, many drivers don’t listen. But with IoT technology, it is possible to keep track of what drivers are doing on their phones while driving and block apps that could be distracting.

IoT apps can also be used to figure out how drivers act and help them improve based on how they drive. IoT is now being used to build cars that don’t need people to drive them. Even though it seems like something from the future, cars that don’t need a driver are already being made. All of the sensors and gyroscopes in these cars are linked to the cloud and the internet.

Using this platform, the driverless car can get information from many different sources about traffic, potholes, sharp turns, speed breakers, and other things that are useful for driving. Self-driving cars can be a great addition to a Smart City to make sure traffic flows smoothly.

5. Health Care

When IoT is used in healthcare, it can change the way healthcare is done as a whole. Doctors, patients, hospitals, and health insurance companies are all part of the healthcare industry as a whole. IoT can help each of these groups and make their lives better. Patients can already get help with their health from things like fitness bands and blood pressure monitors that they can wear.

There are also alarms in these devices that let doctors or family members know if something is wrong. Through the IoT device, it is easy for doctors to find out about a patient’s history and get real-time health data. Real-time health data can also be used to make clinical trials work better. IoT devices can be used inside hospitals to keep track of where medical devices like defibrillators and wheelchairs are, as well as to manage inventory, keep an eye on the environment, and control the temperature.


IoT is a technology that is changing the game in many different fields. IoT apps are being used by more and more businesses and government groups. Slowly, the world is becoming a “Smart” world with “Smart” solutions. IoT has given both businesses and governments many ways to improve their work and become more efficient. Also, IoT professionals have a bright future ahead of them because there will be lots of new opportunities in the near “Smart” future.
