What is IoT ,and How Does it Work?, And what are its applications?, why is it important?


What is IoT?

The internet of things describes physical objects that are embedded with sensors, processing, ability, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the internet.

These devices range from ordinary household objects to sophisticated industrial tools.

Why is IoT important?

Over the past few years, IoT has become one of the most important technologies of the 21st century. By means of low-cost computing the cloud, big data, analytics, and mobile technologies, physical things can share and collect data with minimal human invention.

Why is IoT useful?

IoT allows companies to automate processes and save money on labor. It also reduces waste and improves service delivery, making it less expensive to manufacture and deliver goods and providing transparency into customer transactions.

What technologies have made IoT possible?

While the idea of IoT has been in existence for a long time, a collection of recent advances in a number of different technologies has made it practical.

Access to low cost, low-pressure sensor technology:

Affordable and reliable sensors are making IoT technology possible for more manufacturers.


A host of networks in the availability of cloud platforms enables both businesses and consumers to access the infrastructure.

Machine learning and analytics:

With advances in machine learning and analytics, along with access to varied and vast amounts of data stored in the cloud, businesses can gather insights faster and more easily.

Conversational artificial intelligence:

Advances in neural networks have brought natural language processing to IoT devices and made them appealing, affordable, and viable for home use.

What is industrial IoT?

It refers to the application of IoT technology in industrial settings, especially with respect to instrumentation and control of sensors and devices that engage cloud technologies.

One example is the automotive industry, which uses IIoT devices in the manufacturing process. The automotive industry extensively uses industrial robots, and IIoT can help proactively maintain these systems and spot potential problems before they can disrupt production.

The following are some common uses for IoT:

  • Small manufacturing.
  • Connected assets and preventive and predictive maintenance.
  • Smart power grids.
  • Smart digital supply chains.
  • Smart cities.
  • Connected logistics.

What are IoT applications?

IoT intelligent applications are prebuilt software- as- a- service applications that can analyze and present captured IoT sensor data to business users via dashboards.

IoT applications use machine learning algorithms to analyze massive amounts of connected sensor data in the cloud. Machine learning-based algorithms can identify equipment anomalies and send alerts to users and even trigger fixes or proactive countermeasures.

With cloud-based IoT applications, business users can quickly enhance existing processes for supply chains, customer services, human resources, and financial services. There’s no need to recreate entire business processes.

Examples of how IoT impacts our daily lives, at work and at home:



  • Home security. The IoT is the key driver behind a completely smart and secure home. It allows you to control locks, lights, radios, heating, and camera security all from your phone, so you can monitor how safe your house is from just about anywhere in the world.
  • Activity trackers: It helps in setting fitness goals such as meeting a basic regular exercise activity goal. It can help an individual in self-monitoring their activities.
  • AR glasses: Augmented reality smart glasses are defined as wearable augmented reality devices that are worn like regular glasses and merge virtual information with physical information in a user’s view field.
  • Smart farming: It is a system that is built for monitoring the crop field with the help of sensors and automating the irrigation system. The farmers can monitor the field conditions from anywhere.
  • Smart farming deems it necessary to address the issues of population growth, climate change, and labor that have gained a lot of technological attention, from planting and watering crops to health and harvesting.
  • Digital twins: they are very promising to bring smart farming to new levels of farming productivity and sustainability. A digital twin is a digital equipment of a real-life object of which it mirrors its behavior and states over its lifetime in a virtual space.
  • Ingestible sensors: An MIT research team has developed an ingestible sensor that uses genetically engineered bacteria to detect and diagnose gastrointestinal problems. The sensor is made up of a computer chip and bacteria that reacts to predefined biomarkers by luminescing.
  • Smart contact lenses: The patent application reveals that the smart lenses will be able to take photos, process data related to them, and carry out tasks based on that processed data. A smart contact lens means putting rigid, non-see-through components onto a lens that will be in direct contact with the eye. Smart contact lenses can act as medical devices, health trackers or gauges, and audio and video recorders.
  • Self-Healing Machines: It has an important role in the mass adoption of the technology. There are some research works in this area, but most of them are related to wireless sensor networks or internet networks.
