What is IoT?
The definition of IoT could be the federation and interconnection of devices and objects through a network (either private or Internet, the network of networks). Anywhere all of them could be visible and interact. Regarding the type of objects or devices, they could be anyone. From sensors and mechanical devices to everyday things such as the refrigerator, footwear, or clothing. Anything that can remain imagined could be connected to the Internet and interact without the need for human intervention. Therefore, the objective is a machine-to-machine interaction. Known as an M2M (machine to machine) interaction or M2M devices.
Why Is The IoT Fashionable? What Applications Does It Have?
The Internet has evolved rapidly, allowing IoT to become a reality and not just a vision of the future. The fame of this knowledge lies mainly in all the applications. It promises that it allows us to recover both people’s daily lives and business environments, where it has already remained implemented for some time.
Let us suppose the refrigerator of a house, where the food remains kept, which, in turn, has an expiration date. When food expires, if there is a drop in temperature due to a breakdown, if some food is running out, or simply the electricity consumption based on the number of times the refrigerator door remains open. In this scenario, the fridge could stay connected to the Internet to notify users through their mobile phones.
Another scenario could be home automation, where numerous devices connect to the Internet to make life easier for human beings. For example, voice-controlled devices that remain asked to play a song after a repository on the Internet. Or the devices besides applications that allow controlling all the water parameters in an aquarium or smooth the alarm systems of the houses connected towards the power plants. Security systems connect to the network to notify you when someone enters your home or those devices that allow you to turn on the heating from a mobile phone.
Suppose you think about industrial applications. IoT remains already used in many production plants where devices and sensors connected to the network allow data to be analyzed and generate alarms. And messages are sent to different users to take the necessary actions or even initiate action protocols automatically. Without human communication, to correct or treat these alarms.
Another example of an application would be in the livestock sector, where biometric monitoring and geolocation is a factor that helps farmers to ensure that their animals remain always controlled.
Terms closely related to IoT can be “Smart Cities” and “Smart Buildings,” where IoT devices remain used to improve traffic control, control of water and heating supplies in a building, management of public transport, etc.
What technologies stand used?
As you can see, IoT is already here, and it is a reality. Its scope of application is extensive, and every day more and more devices are emerging that make this technology possible. This technology associated with the IoT allows data to be collected and sent to the network for analysis or even to carry out a previous investigation and then send it to the network.
This communication process is where IoT is evolving. One of the obstacles to overcome is the type of protocol with which these devices communicate (that is, “the language” that they speak between them)—currently, Very new devices or sensors whose communication and connection to the Internet are accessible and direct. Still, there are also many other older non-standard devices whose communication and connection protocol is not trivial. That is where one of these pitfalls comes to remain saved. Additionally, each manufacturer or “vendor” has communication protocols that mean that not all devices are compatible. One of the mechanisms that have remained tried to establish is the creation of an open and standard protocol (proposed by IBM) called MQTT (Message Queuing Telemetry Transport),
Diplomacies For IoT
On the other hand, if you are looking for diplomacies for IoT. You have to consider various aspects such as low consumption besides that they are small. Hence SoCs (SoC, System on Chip) is an essential part of these devices. An SoC is an integrated circuit that contains all or most of the modules that a computer would have (SoCs can remain found in mobile phones, for example). As examples of prominent producers, we have ARM and Intel. However, they are not the only ones, more recent ones such as MediaTek, Qualcomm, or Samsung. Additionally, there are very affordable alternatives for all users, such as Arduino, allowing users to assemble their own devices and control circuits for the home.
Another essential part of an IoT device is the sensors. The processor and the platform are responsible for managing the material, but this must come from the sensors. In this sense, Arduino has made this category of technology available to all users. Additionally, vendors that provide cloud services also offer kits prepared with various sensors. Allowing you to connect with these services quickly.
What Technologies Are Available?
Finally, another technologically vital component to enable the IoT is the technology used for communication between various devices whose location is not close, that is. Communication networks. In this section, you can talk, for example. Of communiqué through a “WiFi” network that. Although it admits a high transmission rate, has a high consumption and a low range. Another well-known example would be a mobile network (3G, 4G, or the future 5G) where the content would be more significant and lower consumption. Additionally, there are other types of specific networks for IoT. Such as Sigfox (with excellent coverage in both the United States and Europe) or LoRa.
To finish, comment that talking around technology in IoT means talking about a series of solutions proposed by different manufacturers. Besides that is in continuous evolution. There is no single technology. But many must remain analyzed to adapt them to the specific solution you want to develop.
