IoT applications connect multiple devices together and help them communicate, from smart watches to air conditioners to self-driving cars. According to IHS Consulting, the number of installed IoT devices worldwide will increase from 15.4 billion units in 2015 to 30.7 billion units in 2020. By 2025, this number is expected to reach 75.4 billion units, with a compound growth rate of 17.21% over the next 10 years.

What is the reason for this increase? What IoT applications have been popular around the world recently? This article explores the reasons behind the increased use of IoT applications and outlines the practical cases used in various industries.

Ten years ago, IoT applications had little use in the market, collecting data, uploading data to the cloud, and then accessing data from a remote location seemed impractical. But now, with the advancement of technology and the upcoming 5G, the Internet of Things has become one of the main technologies in the market.

The Internet of Things consists of two main elements: the Internet and the "things" that connect to the Internet. What the Internet is, no need to introduce, but can talk about what these "things" are. These things, also known as "smart" or "networked" devices, use embedded sensors, processors, and communications hardware to collect and process data from the surrounding environment. They can also communicate with all relevant devices in the environment to gain insights and then act on the information received.

People interact with all of these devices at an initial stage to determine which device has access to which specific information. These devices can then do most of their work without human intervention.

To make it easier for you to understand, let's look at an example. The Philips Hue lighting system is designed to change the way traditional systems use smart bulbs and is touted as one of the simplest IoT applications.

Now, you might ask, what is the difference between a smart light bulb and a normal light bulb? First, you can set when the light bulb is turned on and off. Let's assume that you are anxious to go to work and forget to turn off the lights. In this case, the app detects that the light bulb is still on when it should be turned off, and then sends a notification to your phone via the app asking if it is off or on. This simple action saves you money and helps save energy. Second, this may not be the main factor, but it's really appealing ¨C you can change the color of the lights, and they can even match the color of the light bulb to your party theme.

1.Retail and Supply Management: The Amazon Go unmanned store is a perfect example of such an application. Just download the app, scan your code when you enter the Amazon Go store, then pick up the item you need, and leave the store directly, and the cost of the item you're paying will be deducted from your Amazon account. simple. However, behind the simple is a series of complex technologies, such as the Internet of Things, artificial intelligence and deep learning algorithms, sensors, FRID and more. And you can't ignore the fact that this application is impossible without the Internet of Things. The name, quantity and process of the customer picking up or putting down the product will be transmitted to the cloud in a few seconds through the camera and sensor and communicate with the export card reader, and the automation level has reached an unprecedented height.

2.smart lock: Smart lock has all the basic functions of the standard lock, but a lot more convenience. Smart locks make things simple, no need to manually unlock them, just tap your "smart" device. Some smart locks even provide remote operation, which means you can lock or open the door even if you are a thousand kilometers away from home. Why is this so important? Imagine, on a trip,
Your phone receives a notification that the door is unlocked or someone tries to enter your house. With Smart Lock, you can log in from your phone or laptop by simply connecting to the Internet, tap a few buttons, and your door is locked.

3. Internet of Things in Healthcare: Chronic diseases are characterized by expensive medical expenses and great harm. Although technology can not eradicate chronic diseases at one time, it can make medical expenses cheap and easy to obtain. Let us look at it this way ¨C the Internet of Things is a virtual bridge that connects doctors and patients and treats families as the center. This means that you can sit at home for treatment, which also means better use of resources, reduced access to hospital clinics, and improved time allocation and planning. The Internet of Things facilitates real-time monitoring, and through this, many lives can be saved. In addition, in medical emergencies, such as heart failure, asthma attacks, and strokes, smart medical devices connected to the application can collect patient information and send it to the doctor in charge of the emergency.

4. Logistics: The distribution center is the foundation of the logistics supply chain. The logistics companies have been working hard to improve the operational efficiency of these centers. The Internet of Things helps these companies achieve their goals in the following ways: Security, alarm sensors and cameras use the Internet of Things to help monitor theft and protect goods. You can lock the door, receive alerts for unusual activity, and access the surveillance camera from a remote location with just one application. All of this data can be combined and analyzed to improve the deficiencies. Optimization: The Internet of Things provides comprehensive data on central temperature, all equipment performance, and inventory capacity, which helps improve overall operational efficiency. Many companies are using the Internet of Things to protect their equipment and protect employees from accidents. Imagine if you can get an alert from a sensor on the forklift to inform you of possible hazards, you can stop working immediately and avoid a fatal disaster.

5. Internet of Things monitoring and controlling pollution: Pollution is increasing, especially air pollution. Industries and factories are considering using the Internet of Things to monitor and control the amount of toxic gases emitted into the air. If the Internet of Things is implemented, the sensors in the factory will monitor the toxic gas content, and then anyone working in the factory can get the data with the help of the application. If the gas content exceeds the warning value, the employee will be on the phone. Alerts are received, or an alert sounds indicating they should be evacuated from the workplace. This feature increases the safety of factory employees and provides a better working environment.

In recent years, the Internet of Things has made great progress and flourished in various industries and markets. The Internet of Things not only helps organizations reduce and save energy, but it also helps automate. It spans different use cases, from smart homes to smart transportation to smart agriculture, etc. The Internet of Things has truly proved itself to be an important force to watch.

In short, IoT applications offer users a range of benefits, and there are many more interesting and groundbreaking applications waiting to be experienced. As the company hires skilled IoT professionals to improve business efficiency, the Internet of Things has become one of the most profitable jobs in the current business climate.
