What is IoT?

The way of people living in the 21st century has brought drastic change due to the high availability of the internet around us. There are multiple examples around us to explain how the internet has brought changes in our daily life. This article on IoT gives you detail information on how it has changed the people lifestyle and its application in today's world.

We people have been probably hearing that IoT has brought the drastic change from operation to management and in some cases jobs automation in all industries. How this platform has brought this drastic change? What made this change? Do you wanna know all these? Read the following carefully to get answers for all these

Before knowing to know what exactly it is, let us initially have a look at the evolution

Evolution  of IoT:

The evaluation of  Internet of Things platforms can be  explained below:


In the pre-internet, most of the human to human communication was through a fixed and mobile telephony.

Dawn of Internet:

The world was changed unexpectedly with the origin of the internet. We  people can able to get the desired information within a button click.

What is IoT?

The Internet of Things(IoT) is a network of interrelated computing devices, mechanical and digital machines. These devices contains unique identifiers that transfer the data over the network. It does the work without the human-human interaction (or) human-machine interaction. In other words, it is also defined as a connection on the (or) device and can connect WIFI. This platform has its presence in many places in our daily life. Through this platform, we people can connect kitchen appliances, cars, thermostats, to the embedded devices via the internet. Through low-cost computing, cloud, big data, analytics, and mobile technologies physical things can share and collect the data with minimal human intervention. Moreover, digital systems were capable of record, monitor, and adjust each interaction between the connected things.

Till now, we people have got basic information on the Internet of Things, let us have a look at its architecture

IoT Architecture:

IoT is not just internet-connected consumer devices. It is a technology that builds systems capable of sensing and respond to stimuli from the real world without human intervention. So we need to develop a process flow for a definite framework over which IoT solution is built. The platform architecture generally comprises of 4 stages:


Stage-1 (sensors/actuators):

A thing in the context of the Internet of Things should be equipped with sensors and actuators and thus gives the ability to emit, accept, and process signals.

Stage-2 (Data Acquisition System):

The data from the sensors start in an analogue form that needs to be aggregated and converted into digital streams for further processing, Here the data acquisition systems perform these aggregations, and the conversation functions

Stage-3(Edge Analytics):

Once the Internet of Things data has digitized and aggregated, it may require further processing before it enters the data center. Here the place, where the edge analytics comes into the picture.

Stage-4(Cloud Analytics):

Data that needs more in-depth processing gets forwarded to physical data centers (or) the cloud-based systems

How does IOT work?

The ecosystem of the Internet of things(IoT) comprises the internet-enabled smart devices like sensors, communication hardware (or) processors to gather, send, and act on the data acquired from the different environments. The data connected by the IoT devices is shared by connecting to other edge devices (or) an IoT gateway. Here the collected data can be analyzed locally (or) sent to the cloud for analysis purposes. Besides IoT devices were capable of communicating with other related devices and act as data exchange with another. Here the devices do their job without human intervention. Moreover, people who own the devices can interact with the devices for setting up and give instructions to access the data.

Examples of IoT:

a)A “thing” on the Internet of Things (IoT) can be a car with in-built sensors to alert the driver about the low pressure on tires

b)Intelligent Sensors, UID, and transponders that can be accommodated in machines such as coffee machines, cell phones, and home appliances like lamps, washing machines, wearable devices.

Likewise, there are multiple examples of the Internet of Things, let us discuss some with the application of this platform.

Applications of IoT:

a)Disaster Management :

IoT can be used o accumulate the data related to the specific location using remote monitoring tools and platform analytics. Moreover, with the application of the Internet of Things, we can also get the early warning of the disaster.

b)Health Care:

IoT may have a major impact when it comes to remote health monitoring. Using this platform, we can send the patient vitals to the doctor.


With IoT, we can automate the task of irrigation. Besides a set of sensors such as light, humidity, the temperature  can be used to monitor the field conditions

d)Smart Energy Management:

With Smart grids, energy distribution can be easily optimized. These grids also keep collecting the real-time data by distributing the  electricity efficiently and also reduce the outages

e)Pollution Control :

The IoT platform helps us to continuously monitor the air quality as well as the water quality. Here the data will be sent to the cloud for further analysis. Using the analytics report we can take the proper action for pollution control.

f) Manufacturing:

Manufacturers can gain a competitive advantage by using the production line monitoring to enable the proactive maintenance of equipment when the sensors predict the upcoming failure. Besides  the devices were capable of measuring the production output is compromised. Moreover, with sensor alerts, manufacturers can quickly check equipment for accuracy (or) remove it from the production until it is repaired. Hence through IoT, companies can reduce the operating costs, get better uptime, and thus improve asset performance management.

Hence likewise, there is much application of the Internet of Things that we were habituated to use in our daily life. You people can get more examples of the Internet of Things and its applications by live industry experts at the IoT Online Course.

Final Words:

I hope you people have gained enough stuff regarding the need and utilization of IoT in industry. In the upcoming posts of this blog, I'll be sharing the details of the application of each area with real-time use cases.
