Resumen

This paper presents the design, implementation, and experimental evaluation of an Internet of Things (IoT)-based automatic pet feeding system aimed at improving automation, reliability, and remote management of food and water delivery in domestic environments. The system integrates an ESP32 microcontroller, a precision servomotor for solid food dispensing, a water pump for controlled delivery, and auxiliary sensors for operational monitoring. The software architecture incorporates WiFiManager for dynamic network configuration and Blynk 2.0 as a real-time remote monitoring and control platform. The main contribution of the proposed system lies in its automatic WiFi connectivity management, enabling autonomous reconnection to different local networks without manual reconfiguration, thereby enhancing portability and continuous availability. Experimental validation performed on a functional prototype reports an average food dispensing error of ± 2.5% and a volumetric water delivery error of ± 1.8%. Regarding connectivity, the system achieved a WiFi reconnection success rate of 98%, with an average reconnection delay between 1 and 2 s after network disruptions. The obtained results demonstrate stable, accurate, and reliable system performance, fulfilling key operational requirements of domestic IoT applications. The proposed architecture and reported performance metrics highlight the potential of the system as a practical and experimentally validated platform for intelligent pet feeding solutions. © (2025), (International Information and Engineering Technology Association).
