Protótipo de um alimentador automático para animais de estimação

Abstract

This work presents the development of a prototype for an automatic pet feeder, focusing on simplicity, low cost, and practical functionality. In light of the significant growth of the pet market and the increasing need for solutions that ensure animal welfare during the absence of their guardians, an embedded system was developed using the ESP32 microcontroller, an infrared sensor, and a MG996R 360º servo motor. The device is capable of detecting the presence of the animal and automatically dispensing a portion of food, respecting a minimum interval of five minutes between activations. The structure was designed using 3D printing, promoting f lexibility and low production cost. The prototype was tested with different types of pet food, demonstrating satisfactory performance and reinforcing its potential as an accessible solution for pet owners who wish to automate feeding routines. The results indicate that the proposed system meets the requirements of reliability, functionality, and technical feasibility, contributing to the advancement of technologies applied to animal care.
