What is IoT?

IoT, complete form being the Internet of Things, defines the group of physical objects with software, sensors, processing ability and several other technologies.This helps establish a connection and transfer data with other devices over the internet. The scope of learning IoT in 2022 is immense.

IoT is considered malapropism since the devices connected to any network need to be solely addressable, which means the devices need not be connected to the public internet. With the advancement in AI and learning through machines, the prospects in IoT have risen remarkably.

The scope of IoT is never ending and infinite in the future. Some examples of IoT are refrigerators, air conditioners, and smart TVs which are used regularly. For the proper functioning of these devices, specific instructions are sent across with the help of applications on our smartphones. 

Specific handy and easy-to-use devices such as smartwatches and wristbands are used to record and display blood pressure, heart rate, and walking distance. 

As the famous saying goes by

“IoT will stump IT until clouds and big data come aboard”

How does an IoT work?

Smartphones, local area networks, cloud servers, internet and user applications arE certain gadgets combined to form IoT. The IoT devices are linked with the help of a local network. With the help of the internet, the required information is passed on to the cloud servers. The end user application is the information supplied. The learning provided is mutual interactivity which further guides through all the operations in the IoT systems.

Components in the IoT

  • Things:  As per the definition they are objects which come with sensors and are wirelessly connected to a network which helps in data sharing through the internet. 
  • Local Network: A local network is a group of devices sharing a common network, it helps in retrieving data from the computers which are connected to computers. 
  • The Internet: The Internet connects several devices to servers all over the world. 
  • Back End Services: Any part of services which isn’t visible to the users is termed as back end services. Certain examples cited are smartphone applications, game apps, mobile social networks and much more. 

These four components combined, guide the usage of IoT devices thereby increasing the scope of IoT.

There are several scopes of IoT learning which lead to considerable growth in several sectors . There are certain fields of growth and their scopes which are as follows:

Scope of IoT in Healthcare:

There are several scopes of the Internet of things in healthcare. It is proven to be one of the best-used technologies in the healthcare industry so far. Progressive amenities are provided to patients, doctors and researchers which has to lead to impressive progress in this industry.

Services such as smart analysis, wearable tracking health care devices, etc look into the health of patients and sends it across to the physicians. 

There are certain reasons why IoT is used in the healthcare industry. These can be:

Treatments by error reduction:

IoT devices helps in manual error reduction for precise and on-time results and reports of patients. The analysis provided by the devices and gadgets can lead to error-free reports which lead to a perfect hassle-free lifestyle compared to manual analysis.

Reduction in treatment costs:

Manual diagnosis is an elaborate processand requires expensive equipments and additional hospital charges. This is where IoT devices play their role at cost reduction. This in turn also paves the way for timely, quick diagnosis as well as reduced hospital congestion. 

Easy access to specialists in remote locations:

In certain areas where the healthcare facilities cannot reach, the IoT devices and services can access hassle-free. 

By wearing the IoT devices, the real-time details regarding the patient can be submitted by the computer to the doctors as per the requirements. Thus IoT reaches out the inaccessible locations and provides the ease to communicate.

Scope of IoT in the field of Agriculture: 

There are three essential needs of a human; Food, Clothing and Shelter. Out of this, food is one of the basic and important needs for survival for any human. With the increase in population, there needs to be an equivalent increase in food supplies too, which comes from the agricultural industry itself. 

The increasing population has become a challenge for the agricultural industry. Since there are several continuous changes in climatic conditions and geographical conditions, the food supplies get affected too. 

Here too, IoT plays a vital role with the help of precision farming, agricultural drones, smart farming apps and much more. Below are the details discussed regarding the IoT in Agriculture. 

Precision farming and its scope in IoT

In the present day scenario, communication and information technology have got a vital role to play in agriculture since it is an important tool for smart farming. IoT-based devices are used to observe crop-covered fields. With the increase in technology, the sensors help in measuring the moisture in the soil, as well as the humidity and temperature. With the automated irrigation system paving in, it also helps on usage of water effectively. This is how precision farming helps in keeping a track of the crops and thereby increasing productivity. All this and much more makes farming and the work of farmers easier than before. 

Usage of drones in agriculture

IoT has helped growth in agriculture and farming with the usage of drones. Some of the major tasks of drones include planting crops, spraying pesticides, irrigation of fields etc. Drones make it easy for farmers and agriculturists to track the condition and health of the crops in fields. IoT devices thus play a major role in the making of drones.

Smart greenhouses and their scope in IoT

Greenhouse farming is the process of growing or farming crops in a covered and sheltered area. The area is covered completely or partially by transparent material. This provides favourable conditions for the crops to grow without any hindrances such as harsh weather, pests etc, thereby paving way for the good productivity of crops. Manual involvement is required to keep a check on the factors needed for the growth of crops. The increasing technology has led to the growth of IoT-based greenhouses which has sensors, climate control etc as their features.

Communication through the internet leads to getting hold of accurate information with regards to the environment. This then further leads to the device getting trigged by the actuators which in turn control the greenhouse heaters, fans, windows and lighting to tally with the environment. 

Scope of IoT in the Automotive Industry

In the present era, the automobile industry has got a sudden boost with IoT going hand in hand in this field. The creation of automatic self-driven vehicles has been the biggest growth in the automotive industry. This has brought several changes in this industry. This is when self-driven cars were invented by engineering experts to ensure error-free smooth rides. 

Several brands promote and develop self-driven cars, of which some are Tesla, Google, Audi etc. Internet of things, Deep learning, Artificial Intelligence, Data Science etc are included in these self-driven cars and other such vehicles. 

IoT computers are thus programmed in such a way, that they can build an infrastructure which will help in guiding the making of self-driven vehicles. 

HD cameras, smart navigators, speed controllers, rain controllers, proximity sensors etc. are a few known IoT products. On entering the current location and destination, the GPS trackers in any vehicle guide through the location of the target by guiding and finding the shortest path to any location. The installed cameras guides to capture the visuals from a certain area and then sends the data to the AI-based systems. 

These systems further, interpret and visualise the data from the environment and guides the self-driven vehicles accordingly. 

Similarly the speed is controlled by the speed controllers and proximity sensors guide through the proximity of the vehicles and much more. 

This leads IoT to play an important role in the automotive industry providing several opportunities.
