Abstract
The search for alternatives that facilitate the care and feeding of a pet has created the need to apply current technological development in this type of application, since pet owners have restricted time to stay with them due to their daily duties, studies, work or carelessness. In the region, acquiring an automatic device that dispenses food and water in the same equipment and includes remote monitoring through an app on a smartphone is challenging and can be expensive. Therefore, this work presents the development of an automatic device based on MQTT (Message Queuing Telemetry Transport) to dispense food and water for pets, capable of being monitored and controlled through a mobile device. By integrating multiple technologies and tools such as: programming languages, sensor and actuator management, Raspberry Pi, Arduino, CAD (Computer-Aided Design) design and 3D printing, this IoT (Internet of Things) solution allows to implement an innovative prototype that contributes to improve this social problem not only in our country but throughout the region. The functionality tests validate that the developed device has a short response time and that it allows pet owners greater independence and peace of mind.
