REYNOSO JARDON, Elva Lilia et al. Exploring the internet of things based on ESP8622: tools and case study. Rev. cienc. tecnol. [online]. 2023, vol.6, n.3, e258.  Epub June 25, 2024. ISSN 2594-1925.  https://doi.org/10.37636/recit.v6n3e258.

This project focuses on exploring internet of things based on ESP8266 by the development of an application for mobile devices with the control and monitoring operation of an automatic pet feeder. The document presents a design of a physical structure that carries all the electrical components and manages to make a connection through a server, using the MQTT protocol for messaging in time with the application from anywhere in the world using a Wi-Fi network. A series of tests of the response times of the feeder after entering the application, pressing the button, and using the same network to which the feeder is connected. The maximum response times in the servo motor were 5 seconds while the response times for the sensors were 1 second.

Keywords : Mobile app; Pet feeder; MQTT.
