Rancang Bangun Alat Ukur Kenyamanan Ruang (Termal, Audial, dan Visual) Berbasis Mikrokontroler ESP32

Abstract

Mikrokontroler merupakan salah satu alat yang sering diaplikasikan dengan IoT karena bersifat open-source. Penelitian ini bertujuan merancang sistem monitoring kenyamanan ruang menggunakan ESP32. Penelitian dilaksanakan di Advanced Research Laboratory IPB University dan Puskesmas Bogor Utara. ESP32 dikombinasikan dengan DHT22, KY-038, dan BH1750. Prototipe didesain dan diimplementasikan menjadi sistem monitoring dengan programming. Uji kinerja dilakukan untuk mengkalibrasi sensor dan menentukan kenyamanan ruang tunggu Puskesmas. Nilai eror setelah kalibrasi adalah: 2,03% untuk sensor temperatur; 2% untuk sensor kelembapan relatif; 3,15% untuk sensor kebisingan; dan 9% untuk sensor intensitas cahaya. Hasil pengukuran kenyamanan ruang tunggu Puskesmas berbasis ESP32 menunjukkan: temperatur berada di kondisi tidak nyaman dengan temperatur rata-rata 27,87 °C; kelembapan relatif berada di kondisi tidak nyaman dengan kelembapan relatif rata-rata 70,17%; kebisingan berada di kondisi nyaman dengan kebisingan rata-rata 56,12 dB; dan intensitas cahaya berada di kondisi tidak nyaman dengan intensitas cahaya rata-rata 80,99 lux.

Microcontrollers are one of the tools that are often applied with IoT because they are open-source. This research aims to design a room comfort monitoring system using ESP32. The research was carried out at the Advanced Research Laboratory of IPB University and the North Bogor Community Health Center. ESP32 combined with DHT22, KY-038, and BH1750. The prototype was designed and implemented as a monitoring system with programming. Performance tests were carried out to calibrate the sensors and determine the comfort of the Puskesmas waiting room. The error value after calibration is: 2.03% for the temperature sensor; 2% for relative humidity sensors; 3.15% for noise sensors; and 9% for light intensity sensors. The results of ESP32-based comfort measurements of the Puskesmas waiting room show: the temperature is in an uncomfortable condition with an average temperature of 27.87 °C; relative humidity is in an uncomfortable condition with an average relative humidity of 70.17%; noise is in comfortable conditions with an average noise of 56.12 dB; and light intensity was in uncomfortable conditions with an average light intensity of 80.99 lux
