Projeto de campainha inteligente controlada por sistema de vídeo.

Abstract

The current document introduces the implementation of a low-cost Smart Doorbell, which is installed alongside the doorbell outside the resident’s front door. A smart doorbell is a compact device that can monitor the flow of movement from any individuals near the entrance of house, as well as, control the opening of the front door. It is a widely used device around the world, however in Brazil, this type of device is often too expensive for the average household. Therefore, an innovative and low-cost doorbell which presents accurate results can further expand its usability. This project involves the development of an analog acquisition and signal-conditioning device, controlled by a microcontroller, which is also responsible for sending the sampled signals to an Android application via the Internet. Through the application, it is possible for the user to grant the door’s opening which is associated with this system.
