Fechadura eletrônica controlada por aplicação via Wi-Fi

Abstract

The increase of social distancing caused both by the exponential advance of technologies in telecommunications and embedded systems with very low energy consumption and by the recent coronavirus disease pandemic has had a great impact on relationships and where new technologies are inserted in this environment. It was with this contextual basis that the project of an electronic lock physically composed of an external source fed by the electrical grid was conceived. Through a microcontroller connected to a boosterpack used to display information through a graphic display and to inform the opening and closing operation soundly through a buzzer. Besides that, using an auxiliary board as a switch, a Wi-Fi module and a solenoid lock, the user can control access, whether local or remote, to any room or property in his possession, regardless of where he is, as long as he has Internet access and a Gmail account. Using a web application, it is possible to register yourself in a system to see your residences as well as their available locks. In this way, the user can control the registered devices, and track some information about the operations with a log system. This makes it possible for the owner of the lock to yield, or even grant people’s access, thus allowing a range of new possibilities for renting purposes.
