The Internet of Things makes reference to a very important technological revolution and here you will learn how it appeared and its applications.
We are more and more connected and immersed in the world of technology. Within this technological context, the concept and application of the Internet of Things (IoT) gains more and more visibility.
When it comes to IoT, many people remember smart clocks for exercise monitoring, Smart TVs and even smart cities, and they are right. The Internet of Things is where all this is interconnected.
To better explain how the Internet of Things is present in our routines, I will introduce you to some topics in this article:
What is Internet of Things?
Internet of Things or “Internet of Things” (IoT) in English means that objects, people, intelligent houses and data are connected through the Internet, allowing information exchange about several things in real time.
This allows devices to adapt to the use and routine of users and still be able to predict trends in behavior, for example.
The term was coined in 1999 by British researcher Kevin Ashton, who developed a system of sensors capable of connecting the physical world to the Internet while working on a project of electronic tags for stock using radiofrequency technology called RFID.
What is it for?
Today chips, processors and sensors are increasingly cheaper, more versatile and intelligent. They can be used in several devices in order to obtain and process data.
This integration between software and hardware is the perfect marriage for the development of new technologies such as web 3.0 and real world applications.
In this context, the Internet of Things converges technologies uniting:
- Wireless connection chips: they enable a huge range of devices to be connected to the wi-fi, for example;
- Cloud processing and Big Data: this is where the gigantic data source is stored;
- Geolocation: allows to know exactly the location of the user, to provide services based on their location.
The convergence of these factors has resulted in a worldwide mobilization of collective funding to leverage research related to IoT devices.
If you want to go a little deeper into the Internet of Things, we have a very complete material for you. It connects in the video below:
Internet of things and its applications
Smart helmets: the helmet for Skully motorcyclists, has a rear camera that allows to project in the helmet visor the image of what happens behind the pilot.
Smoke detectors: Nest Protect is a 2-in-1 device that, in addition to being portable, warns your smartphone if there is any change in CO (carbon monoxide) levels.
Electronic locks: Goji Smart Lock is an electronic lock that has a control system that detects, takes pictures and sends them to the owner of the house.
Smartwatches: Among the various functionalities of Smartwatches, health monitoring stands out. It is possible, for instance, to monitor heartbeats, informing the user in case of any abnormality. A report made by Olhar
Connection between patients and doctors: In the wave of wearable devices (Wearables) like Smartwaches, the Internet of Things allows doctors to monitor patients in real time through their clothes, in order to speed up and ensure good diagnoses.
Diapers: for monitoring baby’s health, Mimo company has developed a baby clothing that sends the collected data in real time to the parents’ cell phone about breathing, skin temperature, sleeping position and also the child’s activity level.
Insulin Tracker: The Bee+, is a device that adapts to most insulin pens on the market and still synchronizes data with the smartphone. It generates the report with the glycemic index, date and time of the occurrence and from that it is possible to have more precision about the amount of insulin that can be taken.
Agriculture is one of the great beneficiaries of the emergence of IoT. Thanks to it, it is possible to perform real-time monitoring by means of drones that send the captured images directly to cell phones. There are also sensors that can be installed on the crops, providing information about the climate and soil in real time.
As in other aspects, the Internet of Things also offers great advantages in the educational environment. Among the main ones, we can list:
- More dynamic classes provided by the interaction between different devices;
- More security in the school environment, with real time information about the students;
- Accessibility to students with disabilities (PCD), for example, with the use of devices such as glasses that make reading, helping visually impaired.
Standardization of the Internet of Things
The standardization of the connections between the devices is an essential factor to guarantee their interoperability, allowing the perfect integration and sharing of data between them. There are some initiatives among large companies that seek this goal.
One of them is the HyperCat initiative, which includes UK-based companies such as IBM. The group’s main goal is to create a single, open source standard for sensors and devices to share information more easily, aiming at popularizing this technology.
Security and privacy
Not to mention the disadvantages, there is still much work to be done on the issue of security and also privacy when it comes to the Internet of Things. With a multitude of new online devices, the danger of having everyday information leaked through cyber attacks is constant. In this case it is worth considering measures such as: isolation of connections, access controls and detection of intrusions, in addition to well defined security policies as legal measures for data protection.
You are being monitored!
With the increasingly frequent changes that technology provides, the job market is having a direct impact. Many functions previously performed by human beings are being replaced by machines and several jobs are ceasing to exist.
