Prototipagem de sistema de segurança com localização em tempo real via Smartphone: tecnologia como ferramenta de segurança pessoal

Abstract

With the growth of violence in Brazil, people feel increasingly insecure when carrying out daily activities. Therefore, this work has the objective of developing a system that performs the transmission of the smartphone's location of the user that reported being at risk, through a hardware prototype. This device, developed with ESP8266 microcontroller model ESP-01, connects to the Firebase server and changes the user's state. After that, the Android application recognizes this change and informs the added contacts that the user is in danger, and they can access the real-time location on the map, and can facilitate police action to counteract the situation. The application also allows the user to manage their current state, being able to de ne whether it is safe or at risk and also, with the help of Firebase, can create a new account, log in into the app and recover the password. To these functionalities to work correctly, it was necessary to route the smatphone network to the microcontroller, since it does not have its own network. Finally, tests of the developed prototype were performed, which proved to be functional and e ective for the de ned purposes.
