Abstract

In the domestic sphere, ensuring proper feeding routines for pets is becoming increasingly complex due to the fast-paced lifestyles of pet owners in the city of Cajamarca. Irregular schedules and manual feeding often lead to nutritional deficiencies, dehydration, and poor hygiene. Traditional methods have limitations in terms of precision and efficiency. To address this, this project proposes the development of an automated pet food and water dispenser, controlled by an ESP32 microcontroller and equipped with sensors, motorized mechanisms, and a mobile application for remote monitoring. The overall objective is to develop and evaluate the dispenser's impact on feeding regularity and the operational efficiency of the process. The methodology is pre-experimental, focusing on the design, programming, construction, and testing of the prototype. The materials used include an ESP32, geared motor, solenoid valve, controller, sensors, wiring, and 3D-printed parts in PLA+. Tests were conducted to measure dispensing accuracy, operating times, system stability, and the functionality of the mobile monitoring system. The tests were applied to measure dispensing accuracy, operating times, system stability, and the functionality of the mobile monitoring system. The results demonstrated a reduction of over 75% in the time required to serve food and water, improved hygiene by reducing direct human contact, and a continuous supply of food and hydration. Furthermore, a positive economic and social impact was identified, as it is an accessible alternative with potential for local entrepreneurship. In conclusion, the prototype is presented as an innovative and viable solution aligned with current trends in automation and smart homes.
