Pet Access Control System Using a Mobile Application

Abstract

This work develops a system consisting of a mobile application and an automatic gate implemented with low-cost technology. The devices are linked to a cloud server through the internet. The design of the system consists of a gate that incorporates a motion sensor to detect the pet, for this a passive infrared sensor is used. The electronic circuit of the gate is based on the ESP32 board. This device sends notifications to monitor when the pet approaches this area. The system consists of two modes, manual and automatic. In manual mode, the user decides to open the gate or not, while in automatic mode the gate opens whenever it detects the pet. On the other hand, the mobile application has been designed to control the operating mode. The application's user interface presents a warning when the presence of the pet is detected and allows the gate to be activated remotely only when it is in manual mode. The cloud platform used is Firebase, this remote database records the latest states of the fields shared by both devices. 3 pets were tested for 1 week to ensure continued system performance. As a result, adequate communication was obtained between the elements installed in the gate and the mobile application.
