Resumo:
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.
