Desenvolvimento de um rastreador utilizando dispositivos IoT e integração com mapas

Abstract

Currently, the Internet interconnects everything and everyone, connecting not only computers and smartphones, but also with everyday devices, thus receiving the name Internet of Things. This evolution made it possible for devices to be interconnected to tracking systems, either for security, or to obtain the current location. Based on this context, the present work presents the methodology and development of an open source tracking system to be implemented using low-cost IoT modules. Along with the tracking system, a smartphone application was also developed, which aims to draw the trajectory of geographic points on a map, allowing a graphical visualization of the tracking of devices. To validate the proposal, a bench prototype was created and connected to the Internet through the Wi-Fi integrated module. In this prototype, the IoT device communicates with the smartphone through a microservice developed in python. The communication between the controller board and this microservice takes place via the MQTT communication protocol. In the tests carried out, the prototype was successful in collecting the geographic coordinates and storing them into a database. An API, also developed in this work, allows access to the stored points, so that the smartphone application renders, showing the tracking of the devices.
