What is known today as the Internet of Things (IoT), refers to the connection of computer devices included in common objects, through the Internet. This connection allows objects to receive and send data to carry out functions such as remote control of devices, receiving notifications, updating states, among others.
Thanks to advances in technology, currently the number of artifacts that can be part of the IoT is immense. From a smart washing machine to an autonomous car, they are part of this network of devices with access to the Internet and information from other objects.
How is the Internet of Things used?
Thanks to the almost unlimited access that people have to a wireless Internet connection, and all the possibilities that this new technology provides, its acceptance has been great.
The IoT is currently used in the following areas:
Home automation
One of the spaces that serves as the setting for the operation of the Internet of Things are homes.
One of the main applications that the IoT allows is that of devices that can be controlled by voice, and that also control other devices. Additionally, security systems that allow users to connect from their smartphones, and notify of any danger, are very popular. The IoT is also used to control the temperature inside the home, turn the lights on or off, program the television, etc. All this with a voice command or through your smartphone.
In the daily routine
The Internet of Things can facilitate many tasks that are part of our daily routine. We can set our alarm clock so that a few minutes before the alarm goes off, it activates our toaster or coffee maker. In this way we will have part of our breakfast prepared, before getting out of bed.
On the other hand, there are cabinets that can notify us about the expiration date of the products it contains. In this way we can buy food in a timely manner. Some IoT refrigerators also fulfill this function.
In the world of industries
Due to the facilities it offers, the IoT is being used in certain production plants. Thanks to the connection that can be established between some devices and sensors, warnings or notifications in some phases of the process can be generated. This allows manufacturers to know if something is wrong, or to make the respective decisions regarding a case.
In the livestock sector
In this work area, the IoT facilitates connected devices that can be assigned to each animal. This has been considerably facilitating the work of ranchers, in conjunction with geolocation.
In smart buildings
With the correct use of Internet of Things devices, building managers can do their jobs much better. The IoT allows them to control the supply of water, electricity and even control the thermostat. Additionally, the sensors and devices installed in the building send data that helps determine if there is a problem. This type of notification allows a timely repair or solution of the situation.
On the other hand, those responsible for building security can also benefit from the IoT. Receiving alerts about any risk or danger.
Smart cities
With the implementation of the IoT in the most outstanding aspects of a city, these will be increasingly intelligent. The connection of traffic systems, and the use of the Internet of things in public services, cities will advance more and more.
It can provide better transportation, lighting, garbage collection, watering green areas, and much more.
Vehicular driving
Thanks to the use of IoT in combination with other technologies, the area of road safety will have a significant advance. Automobiles will be able, with a certain autonomy, to make timely decisions based on information in real time.
Data security with the use of the Internet of things
Although the Internet of Things brings us a lot of benefits and facilities, we must be cautious when using it. The essence of the IoT is to establish wireless connections between devices for the exchange of information. By sending and receiving information through the Internet, the information would be exposed to the risks of the network.
That is why certain security measures must be taken to make proper and safe use of the IoT.
Passwords
This is one of the first targets that hackers attack. That is why they must be defined in a complex way, that they are unique, and change them from time to time.
Avoid using the same password for different applications or accesses.
Secure network services
The Internet service you use must have the various security systems of the case. A vulnerable service is an open door for cyber attacks. Make sure you have a provider that has all the appropriate safety barriers. Otherwise your data could be exposed and be manipulated with negative consequences.
External tools
All tools external to IoT devices, such as mobile applications, interfaces and hardware, must be properly configured. If you use a web, API or app that does not have the proper configuration and control, it could compromise the IoT devices. The same would happen if some external hardware or software component is used that does not have the proper update.
Data encryption
Because data storage and exchange is necessary in an IoT environment, it must be protected. One of the best ways to protect the data exposed through an Internet connection is by encrypting it. To do this, encryption algorithms can be used.
The Internet of things in the future
According to the studies carried out, it is expected that there will be billions of IoT devices by the year 2025. Without a doubt, by then people will be much more used to the connection between their electrical devices and how they work.
Likewise, it is estimated that in the short term both companies and cities will further incorporate the Internet of Things into their daily operations. This with the idea of automating tasks, controlling certain operations and objects from a distance, and gathering information that is useful to them.
On the other hand, and in no more than three years, most companies are expected to use the IoT no matter in which sector they operate.
