Top 10 Real World IoT Applications

Internet of Things, popularly known as IoT, is a technical concept that allows various digital and mechanical computing devices, humans with unique identifiers, objects, and even animals to stay connected over a general platform in order to communicate and transfer data without any interactions between humans or computers but with an IP (Internet Protocol) address.

This advanced technology is widely used by all big organizations to share data both inside and outside of the premises. 

IoT has its own set of applications that helps a firm to grow in terms of its service, production, connections, and communications. This article will deal with IoT applications to elucidate the importance of IoT usage.

Need for IoT:

IoT is widely used in almost all of the big organizations and MNCs due to its benefits which helps them to improve their standard of communication and work by offering them a platform to share data across the globe without any restrictions.

Data is the reflection of a business or a company’s performance and by sharing data with all of its stakeholders, the true picture of a firm is brought to light, leading to further updates and corrections. 

  1. IoT brings in transparent customer-relations.

  2. IoT’s ‘track and monitor’ feature helps one to control the organization’s happenings from one place.

  3. Sharing data/insights lead to better decision making.

  4. It provides the real picture of one’s systems and their usage.

  5. The automation feature reduces work pressure and the money spent on laborers.

  6. A company’s service can be improved without spending much money. 

  7. IoT has become the base for today’s lifestyle.

Principals Followed by IoT Application Developers: 

The applications of IoT are designed and crafted by IoT professionals who focus on including various features and factors like network connectivity, sensors, interactive devices, actuators, data analyzing elements, and a platform that connects the users and the application for interactions,

just to make sure that IoT becomes applicable for both industrial products and business services. This is also called M2M (Machine-to-Machine) App Development. 

Here are the basic Principles, an IoT Application Developer must keep in mind:

  • Design an application that is apt for effective data management. 

  • Develop the security for the applications, just to make sure that the data is collected safely and sound. 

  • Sharing and communicating data should be very effective and should be organized too.

  • The usage of the cloud and its link with IoT applications is vital.

  • A platform for IoT is a mandatory step that a developer needs to develop.

Top 10 Real-Time IoT Applications 

1. Healthcare:

IoT Application - Healthcare

IoT deals with healthcare through its connection mechanisms. Devices like smartwatches or fitness bands or stress detectors are a great example of IoT applications that involve the welfare of the public.

Other smart medical devices used in companies lead to a better healthcare system too. An individual’s health and the ways to improve it are all known to them via these healthcare devices. The base for this application is IoT’s ability to connect devices, collect data through sensors, and analyze them to form the right results. 

2. Industrial Use:

IoT Application - Industrial

As the name suggests, this application deals mostly with the industrial sector than the personal sector. IoT applications deal with developing the industry and it's working methods with the help of software used for data analysis, sensors, tracking devices, and machines that are effective and masterly.

These help a firm to have accurate, enhanced, and transparent functioning. One can not only improve things but can also identify the damaged spots for an accurate cure. When IoT is used in industries, a sustainable approach is well-established.

3. Smart Homes:

IoT Application - Smart Homes

When the homes are at their best when their lives will be the best too.

However, in order to make your homes smart, the application of IoT is necessary as it helps the owner to control and supervise their lights, security, fans, water supply, and other home devices through any of their smart devices.

In short, a smart home is a modern-technological experience that will help the owners save their money, time, and energy spent on their daily-life.

4. Smart City:

IoT Application Smart Homes

When the homes in the city become smart, so does the city which gets to have many infrastructural developments due to IoT applications. IoT also has its way around in the transport sector, government services sector, traffic management sector, health care, agricultural sector, water and energy sectors, and also in the waste management sector, which leads to a sustainable way of living by removing the difficulties of the living population. 

Cities are also protected and observed for security and development through IoT.

5. Agriculture:

IoT Application - Agriculture

Agriculture is always the need-in-hour service and with the due increase in population, its demand rises too. However, in order to meet the current and future farming needs, farmers should use smart methods and techniques.

IoT offers many such smart techniques like its automation feature helps the farmers to fertilize their plants at regular intervals, keep a check on the usage of water, be aware of the right time to harvest. analyze the soil’s texture, nutrients, and also its ability to yield.

Livestock can also be monitored through IoT’s sensor tools. In order to predict the weather before/during/after a yield, one can use AIIMETOE / Pynco, the 2 best IoT farming devices.

6. Smart Supply Chain:

IoT Application - Smart Supply Chain

A supply chain deals with the process involved in delivering a product or service to a consumer. When the traditional methods are used, this supply chain charges more manpower and thus more money, energy, and time.

However, when IoT is applied here, then through its tracking systems (GPS / Radio Frequency) and sensors, one can easily, without much pressure and money involved, can track their goods, the shipment process, and also the transportation operations.

IoT sensors can be used to know the effectiveness of each machine and its work settings can also be changed, if necessary. With less manpower, but more work is done, the company’s work is optimized at all levels.

7. Retail Purpose:

IoT Application - Retail Purpose

Retailing is all about connecting with the consumers on a more personal level and IoT enables a retailer to stay connected with their consumers with the help of their smartphones.

Through this connection, the retailers get real feedback from their consumers and also helps them find the demand in their particular place in order to change their goods supply accordingly.

On the whole, the overall in-store experience is enhanced to meet the needs of their prospective customers, goods are advertised effectively, and the supply chains are well maintained. Even payment procedures are enhanced. 

8. Transportation:

IoT Application - Transportation

Smart cars are a great example of how IoT is used for controlling, monitoring, and driving a car with the help of a smartphone / any other smart device through integrated sensors and a central computer installed in the car.

Manufactures also use such sensors to know about their supply-chain and hence attach a sensor in the vehicle that transports their goods. Even taxis work based on this IoT application, in order to pick-up / drop their customers from and in their desired destinations, respectively. One can also get these sensors to usage while trying to park their smart car in their garage. 

9. Smart Grid:

IoT Application - Smart Grid

These grids of IoT are also known as Power / Intelligent grids as they brilliantly manage the power resources by keeping a regular/automated check on the supply and demand of energy/electricity.

It’s transmission, consumption, distribution, and generation are all identified and monitored. This leads to an increase in the economics and efficiency of electricity/energy. The Solar Panel is one of the best examples of a smart grid. 

10. Wearables: 

IoT Application - Wearables

Wearables refer to the smartwatches produced by Apple, Motorola, and others, Myo Gesture Control, the LookSee bracelet, and many more which work with a sensor and software. They are used by the users to know about themselves for development and enhancement.

Wearables can be used by users for fitness, entertainment, GPS, and also other health purposes. However, the energy/power released or used by IoT in these wearables are very less and thus they do not affect the users.
