SMART LOCK: desenvolvimento de uma fechadura elétrica acionada por voz

Abstract

This work proposes the development of a prototype called Smart Lock, as a smart lock solution controlled by a mobile application and with voice control through the virtual assistant Alexa. The developed device is an ESP32CaM microcontroller, for control and communication with other devices and applications. This system contains a mobile application, capable of performing identification login, user and lock registration, and lock control, developed in Flutter. To perform interoperability between devices, using middleware, characterized by security in data transmission, called FIWARE. After the tests carried out on the system, the results obtained were satisfactory, managing to control the lock through the mobile application and through voice. This prevents unidentified users from having access, both through the mobile application and through the Alexa virtual assistant skill. After access analysis, it is observed that the developed device has practical potential for use, proposing a solution for people to have better control of the locks, especially people with reduced mobility.
