Petification: Node-RED Based Pet Care IoT Solution Using MQTT Broker

Le résumé fourni par la source

An increasing number of families have pets, but for owners who often leave home, taking good care of their pets is challenge. Most previous research on remotely feeding and watering pets uses a limited-feature of IoT platform. In this study, we propose an IoT solution, Petification, using the open-source project Node-RED with MQTT messaging protocol. Petification provides information about device connections, leftovers, food and water consumption through a web-based dashboard. It also provides an error notification service and remote feeding service. We mounted the load cell, HX711 amplifier, Raspberry Pi Zero W on the water supplier, and the MG90S servo motor on the Raspberry Pi of the feeding machine. Petification operated as suggested and provided emails or WhatsApp messenger-based error notifications and automatic feeding services when water or food ran out. In addition, we tested the accuracy of the automatic feeding amount of the food and found the average accuracy to be 88.38%. Future work includes modifying the food serving gate design of the machine to improve accuracy.
