You are working and soon you realized that you forget to switch off AC, now what? Now you need to go to home and off the AC. But what about your work? And that long way of wasting time? Here when Internet of Things come into play. What if your smartphone is able to control all that stuff and you do not need to go home? Easy, right?

IoT is doing these things, and I am not only talking about switch off the AC but IoT is more than that. From smart-cars which do not need a person to drive and you are able to take a ride on your own without texting to a person or call them. Just use the IoT smart applications and a self-drive car will reach at your destination.

See how technology is able to give this type of life in which you are not depending on anyone and do all things by yourself. Lets discus IoT in detail.

What is Internet Of Things?

Until a few years ago the internet was not this much good and facilitated. But now things are changing because technology is changing day by day. Now with IoT, practically all devices are connected with the internet and monitor remotely.

It is a system of interrelated devices connected with the internet to join, transfer, and receive data from one device to another.

To understand what exactly IoT is, let’s take an example of devices in a small home, like AC, Doorbells, smoke detectors, water heaters, and security alarms, which can be interconnected with each other to share data with the user through a mobile application. The user can now get details inside into the working of all devices around him.

Until recently the internet helped people to connect, but now objects and things have the ability to sense the surroundings to interact and collaborate with one another.

Another example from our daily life is, in the morning when your alarm goes off, the IoT system can open the windows, run on the coffee machine for you, and even turn on the water heater. The seamless functions are taking place in the background of all of this, from effective communication between devices to the accurate process in data received, a lot of components are involved.

In the context of IoT devices, two categories are found,

  • General Devices

General Devices are the main components of the data hub and information. They are connected by internet to exchange the data. Home appliances are the best examples of general devices. For microwave, security system, air conditioner etc.

  • Sensing Devices

Sensing Devices devices are included sensors, and actuators, they measure the temperature, light intensity, and other things. But how are these devices work?

These IoT devices are connected with the help of gateways. These gateways or processing notes processed the information from the sensors and transferred into a cloud. Here cloud is a data collecting place that also processes this data. Wifi, Bluetooth, and other wireless or wired devices are used to provide connectivity. Applications need to connect with information generators and this work is done by tiny sensors that provide information to the devices.

Let’s take a simple example to understand it more, suppose you have to water your garden, instead of doing it daily by yourself, you do it by using IoT. is this possible? Yes, it is, the sensors and actuators were installed, the information when moisture value down in the soil of the garden, send to the IoT gateway with the help of MQTT or HTTP than the data is transmitted to the cloud with the help of wifi, or other things,  once the moisture has dropped the system is immediately triggered and the spring lasered turned on. Here the details of the information in the cloud about when they were turned off, the report is sent to your smartphone. From here you can control it easily.

With the improved response, monitoring and analytical capabilities IoT can be adopted by most industries and dummies. It is the world of opening doors and endless applications. Today IoT is being to lessen the burden on humans’ in today’s life. IoT is used for smart homes, in watches, smart cars, smart framing, smart shopping, and many more. The future is IoT is looking more beneficial in upcoming years. IoT is a vision to connect all devices with the power of the internet.

Important IoT Case Studies in 2020

The days are ending when we are waiting for a good quality of life, facilities to those areas which are not able to achieve such benefits. IoT is taking place everywhere and benefiting us. The following are some of the case studies about the usage of IoT in human life, and how this system makes many things easy for us not right now but in upcoming years too.

1- Can Cow Be an IoT Platform?

Yes, they are, but how is it possible? Joseph Sirosh, a Corporate Vice President and Chief Technology Officer of AI in Microsoft's Worldwide Commercial Business stated that, everything is possible with the help of IoT. He named this as Connected Cows, in this system parameters on the foot of a cow are connected. These parameters are very reliable and have 5 years of battery life, also able to survive a hard atmosphere in the frame, and its consistently measuring the number of footsteps that cow takes in a day. Is that important to measure them?

Well, yes they are able to give us lots of data about cow behaviors. The data is sent to the cloud and there is a service that analyzes the number of steps cows take. Two benefits are taken from this data, the first one is to detect health issues early and prevent the loss, and the second is to improve cattle production by accurate detection of estrus which is also called heat. Here the animals have a short period of heat where they are ready to have babies. Through accurate data, the possibility of knowing entrusting is high. It is hard to detect all cows in the farm right?

Here IoT helps them out by creating a graphic data of footsteps taken by a cow.  If the line goes downwards in the graph then it is normal, but if the lines goes upward in the red direction at a high level it means that the animal goes into heat, the cow will take more and more footsteps. All data is sent to the smartphone of a farmer from the cloud. One more interesting information is the time this goes into the heat period, in the first half time if Artificial Insemination is taking place cows can get the female baby and if it happened in the second half of time cows are supposed to have a male baby cow. See how IoT is helping the farmers. Now farmers have under their control either they want more milky cows or other male cows.

2- IoT The Future Super Market

It’s not just about technology but applying technology to improve the human experience. This case study on Italy’s biggest cooperative shows the Super Market of the Future.

They apply IoT to establish social interactions.

In this market, you can take whatever you want and the details about that product are shown in front of you, from where the product has come, how much time can we use it, price and even detail of how many proteins, vitamins it has and what are the benefits of that product. Every single detail that we want to show on the screen in real-time. Just take nay thing and do not need any person to help you out. IoT technology is out there to solve all your questions.

Now this will help the food market to know which types of things people want, the relationship between customer and business is improved by trustful information. Businesses will gain more opportunities to ensure the need and demands of more and more people.

3-IoT in Healthcare

When it comes to healthcare it is important to ensure that everyone at any location takes benefits from healthcare facilities.

  • Remote Patient Care:

In many parts of the world, residents live miles away from the nearest hospital. As such, when there is an emergency, it takes time for them to reach the healthcare facilities. For healthcare providers, it become difficult to visit patients with bad condition frequently. The issue with time-consuming commute can be solved with the remote patient care powered by the IoT.

The connectivity can allow healthcare professionals to assist patients with prescriptions, medication, and also measure their bio metrics using sensors and remote equipment. Patients can connect any wearable or portable device to the cloud and update the data in real-time.

  • Emergency Care:

Emergency care outputs are based on time, accuracy, and the availability of contextual information. Moreover, it also depends on the quality of the data received during the emergency call and the information collected while the patient is being transported for immediate care at the healthcare facilities.

Here, IoT can help in collecting data accurately, which can be accessed by emergency care staff such as paramedics or staff in the ER for quick and better medical assistance. This data also helps the hospital to be better prepared for the care.

  • Augmenting Surgeries

When it comes to healthcare, IoT has penetrated operating rooms as well. Think of connected robotic devices, which are powered by Artificial Intelligence and are used to perform various surgeries.

These operations are all about increased precision brought by robot-assisted surgeons. Moreover, connected devices and IoT applications can perfectly streamline the activities of the medical staff at both pre and post-operating stages. In both cases, IoT sensors can be used to collect, transmit data, and analyze it.

This helps record the details and therefore is used in preventing surgical complications.


There are many more things in IoT that will be taking place, for example, solutions to water, now the applications of IoT are able to supply water at every location. The gas line will be soon facilitated by everyone with the help of IoT and good quality of air is also now made possible by this system of technology. These things are already taking place in China, and the so-called smart cities of the country.

The above information about IoT gives us an idea of how this technology makes our lives so easy and easy to make decisions at the right time, to create a well-facilitated future.
