Application of the Internet of Things in the Development of a “Smart” Door

In this article we propose the development of a prototype that consists of two systems that make a door "intelligent". These door-coupled systems allow a person through an application to have control and access to the door, gaining information about who the door is by unlocking and locking it without having to move to the door. For the development of these systems was used the microcontrollers of the esp8266 family, as these allow connection to wi-fi network, making other devices with access to this network can connect, such as a smartphone with application. During the development of the prototype one can observe the complexity for the production of the application and the communication between the systems by wi-fi. However, the low cost of systems and the availability of peripherals that allow the integration of these systems with the most varied applications, make electronic security accessible to all those who wish to enjoy, further enabling technological inclusion in society.
