Sistem Monitoring Lingkungan Berbasis IoT dengan Indikator Suhu, Kelembapan, dan CO2 di Perpustakaan IPB University

Abstract

Teknologi Internet of Things (IoT) telah merubah cara berinteraksi dengan lingkungan, khususnya dalam memantau kondisi perpustakaan untuk menjaga kenyamanan dan kelestarian bahan pustaka. Penelitian ini bertujuan mengembangkan sistem monitoring lingkungan berbasis IoT dengan indikator suhu, kelembapan, dan CO2 secara real-time dan berkala di lingkungan perpustakaan. Metode yang digunakan meliputi penggunaan ESP32 sebagai mikrokontroler, sensor DHT22 untuk mengukur suhu dan kelembapan, serta sensor MQ135 untuk mengukur CO2, dengan protokol MQTT untuk pengiriman data monitoring. Hasil penelitian menunjukkan bahwa pada ruangan Co-creation Lounge rata-rata suhu berada di rentang hampir nyaman, kelembapan baik, dan konsentrasi CO2 sangat baik. Ruang Ideas Lounge menunjukkan rata-rata suhu berada di rentang hampir nyaman, kelembapan baik, dan konsentrasi CO2 sangat baik. Terakhir ruang baca lantai 3, menunjukkan rata-rata suhu berada di atas rentang hampir nyaman, kelembapan di kategori lembap, dan konsentrasi CO2 dalam kategori sangat baik.

Internet of Things (IoT) technology has changed the way we interact with the environment, especially in monitoring library conditions to maintain the comfort and preservation of library materials. This research aims to develop an IoT-based environmental monitoring system with real-time and periodic temperature, humidity, and CO2 indicators in the library environment. The method used includes the use of ESP32 as a microcontroller, DHT22 sensor to measure temperature and humidity, and MQ135 sensor to measure CO2, with MQTT protocol for sending monitoring data. The results showed that in the Co-creation Lounge room the average temperature was in the almost comfortable range, humidity was good, and CO2 concentration was very good. The Ideas Lounge room shows the average temperature is in the almost comfortable range, humidity is good, and CO2 concentration is very good. Finally, the 3rd floor reading room, shows the average temperature is above the almost comfortable range, humidity in the humid category, and CO2 concentration in the excellent category.
