Application of Internet of Things (IoT) Technology in the Sound Monitoring System for Swiftlets in Kendari City

Abstract

This research implements Internet of Things (IoT) technology in a sound monitoring system for swiftlets in Kendari City. This approach addresses the inefficiencies of the manual system currently utilised by farmers. This study focuses on the inefficiencies in operating swiftlet sound devices, which requires farmers’ presence to control the audio system. This research uses a prototyping approach which involves the steps of needs identification, system design, prototype construction, and testing, which consists of black-box testing and evaluation of the Blynk interface. The system designed comprises a NodeMCU ESP32 as the main controller, a DFPlayer Mini as the audio player, a speaker for audio output, and the Blynk application designed as the interface. The tested system met all the operational and design requirements and allows for remote control of the playback of the recorded swiftlet sounds with an average control response time of one second. The system designed demonstrates that operational costs, inefficiencies, and on-site monitoring are remote; presence control of sound playback is possible. IoT technology incorporates operational efficiency and monitoring systems in real time. This research has the practical outcomes of developing an effective, uncomplicated, and inexpensive system that improves productivity of swiftlet farms and provides a prototype for incorporating digital technology into agriculture and farming. In summation, the use of IoT technology for monitoring and managing swiftlet sounds is effective and has opportunities for advancement into smart, real-time, data-based systems.
