What You Should Know About IoT Devices

Today many people remember the world before the advent of the Internet. The modern world has changed beyond recognition. You can control a washing machine or a heating system simply from your phone, and scientists can record and instantly receive research results. All this became available thanks to IoT – the Internet of Things. These devices have an Internet connection and can be used in almost all industries. If you are new to this area, let’s tell you more about this technology.

What Is IoT, And Where Can It Be Used?

Many need help understanding what IoT is. In fact, it is any device that has an Internet connection. So, your smartwatch or a bank card that can make contactless payments is also IoT. However, their number continues. Today, smart home technology is trendy, which allows you to adjust the lighting and temperature in the room, turn on electrical appliances, and much more. IoT can also be used in urban development. In developed countries, smart traffic lights are actively used, which can adjust the speed of switching red to avoid traffic jams and reduce carbon dioxide emissions into the atmosphere. Smart trash cans are also widely used. They signal to the appropriate services about how full they are, which helps prevent the appearance of landfills and more logically route the garbage truck.

But IoT was most widely used in the healthcare system during the pandemic. With the help of this technology, doctors can quickly and efficiently track the condition of patients remotely.

Also, it can be widely used for home security. Special sensors can detect burglary, sweat, or fire and quickly inform the owner of the apartment and the relevant services (security company, firefighters, or plumbers) about it.

Today, this technology can be used in almost all industries. Every company will be able to find its benefits from the use of IoT, regardless of the field in which it operates, and more and more startups are investing in the development of new contacts of smart devices with a person.

However, do not forget that the development of program code alone is only a small part of the work. Such smart devices have a lot of people’s personal information and the priority here is to keep the security and stability of all smart devices at a high level.

On the website of the testing company https://testfort.com/iot-testing you will find specialists who are engaged in software testing for IoT. The tasks of this company are to identify not only errors in software development, but also load testing, penetration testing, device compatibility, their usability, and much more.

How Does It Work?

Most IoT has a relatively simple principle of operation. At the heart of this, a device always performs some action. Usually, some kind of sensor is chosen for this, which receives information and transmits it in real time to the main computer or smartphone. Each of us knows how smart watches work. They show the time and record how many steps we took during the day and how far we walked. At the same time, you have an application on your mobile phone that transfers this data to make it easier for us to manage the received data. At the same time, IoT can perform more complex actions. For example, some devices can measure heart rate, blood pressure, or blood sugar completely imperceptibly to a person. As soon as it rises above certain levels, the person receives a notification on the phone asking them to stop the physical activity or take medication. When the specified indicator becomes critically high, the device can independently call an ambulance and the patient’s relatives. It allows us to provide medical assistance to people who need it even faster.

The signal to the host computer or smartphone is transmitted via the Internet, hence the name of this technology. That is why a stable connection to the network is of great importance for the operation of such devices. In total, four components make up an integrated IoT system:

Sensors or devices;
Connection;
Data processing;
User interface.

Test solutions for IoT devices include checking each of them. The tester’s task is to check how these components work correctly and how compatible they are. If everything is in order, you will have a convenient device to solve your goals and objectives.

Development Trend

IoT has appeared relatively recently, but it has already become very widespread. In 2011, the number of such devices was 1 billion; by 2021, this has increased to 43 billion. At the same time, during the pandemic, their number began to grow faster. It’s awe-inspiring.

This technology continues to evolve with the introduction of 5G, which has made it possible to transfer information much faster. It has positively affected working with AR / VR without delays and buffering.

In addition, artificial intelligence and machine learning are actively used for better data processing. It helps devices better analyze the sensor’s data and more effectively solve many problems. It is especially true in the healthcare system.
