Judul: Design and Build a Room Comfort Measurement Tool (Thermal, Audial, and Visual) Based on ESP32 Microcontroller
Abstrak: 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

Judul: Design and Build a Room Comfort Measurement Tool (Thermal and Visual) Based on Arduino Uno
Abstrak: Perkembangan teknologi di bidang mikrokontroler yang semakin maju dan sifatnya yang opensource memudahkan pengguna dalam mengaksesnya. Penelitian ini bertujuan merancang dan membuat alat ukur kenyamanan ruangan (termal dan visual) menggunakan mikrokontroler arduino uno. Penelitian dilaksanakan pada bulan April hingga Oktober 2022 dan berlokasi di Kota Medan dan Kota Bogor. Metode yang digunakan yaitu metode kuantitatif. Alat yang dibutuhkan pada penelitian ini adalah arduino uno, sensor DHT11, sensor BH1750, breadboard, LCD, I2C, box elektronika, kabel jumper, kabel USB, solder, RTC, baut dan mur, environment meter, dan adaptor. Penelitian diawali dengan mendesain prototype pada software Proteus 8 Professional, kemudian implementasi hardware, programming, dan pengambilan data untuk keperluan kalibrasi alat. Nilai rata-rata persentase error pembacaan sensor parameter suhu, kelembaban relatif dan intensitas pencahayaan berturut-turut bernilai 1,56%; 2,95%; dan 0,76%. Sementara itu, menggunakan extension berturut-turut bernilai 1,74%; 2,73%; dan 1,31%. Hasil tersebut menunjukkan alat monitoring yang dibangun dapat beroperasi dengan baik karena nilai pembacaan mendekati sebenarnya., Technological developments in the field of increasingly advanced microcontrollers and their opensource nature make it easier for users to access them. This study aims to design and create a measuring instrument for room comfort (thermal and visual) using the arduino uno microcontroller. This research was conducted from April to June 2022 and is located in Medan City and Bogor City. The method used is quantitative method. The tools needed in this research are arduino uno, DHT11 sensor, BH1750, breadboard, LCD, I2C, electronics box, jumper cable, USB cable, soldering iron, RTC, bolts and nuts, environment meter, and adapter. The research begins with designing a prototype on the Proteus 8 Professional software, then hardware implementation, programming, and data collection for tool calibration purposes. The average percentage error of temperature sensor readings, relative humidity and lighting intensity are 1.56%, 2.95%, and 0.76%, respectively. Meanwhile, using extension is 1.74%, 2.73%, 1.31% respectively. These results indicate that the built monitoring tool can operate properly because the reading value is close to the actual.
