Optimalisasi Smart Relay Zelio Sebagai Kontroler Lampu Dan Pendingin Ruangan
Pada implementasi aplikasi elektronika, pada umumnya lampu dan pendingin ruangan menggunakan saklar manual yang berarti bahwa saklar hanya bisa dioperasikan secara manual. Sehingga konsumsi daya listrik tidak terkendali dengan baik. Aplikasi ini bertujuan untuk mengembangkan system yang pernah dibuat sebelumnya dengan menambahkan pengendali lampu ruangan menggunakan sensor photo control yang akan bekerja dengan sinar matahari dan pengendali ruangan menggunakan infrared sensor motion yang akan aktif jika ada pergerakan dalam ruangan dan relay sebagai kendalinya. Dalam system ini juga dirancang menggunakan switching mode power supply (SMPS) supaya supply tegangan untuk system tidak terpengaruh oleh temperature dan dalam memprogram zelio menggunakan perangkat lunak Zelio soft 2. Untuk system pengontrolan menggunakan relay sebagai rangkaian control pengaman. Hal ini dilakukan agar zelio, sensor photo control, sensor PIR, power supply, lampu dan pendingin ruangan tidak terhubung langsung dengan tegangan referensi. Selain sebagai factor safety, control manual dari lampu dan pendingin ruangan tetap dapat digunakan. Dari hasil perancangan yang dibuat system dapat bekerja dengan baik sesuai dengan program yang dibuat. Sensor photo control dan sensor PIR dapat digunakan untuk menyalakan lampu serta mendeteksi pergerakan orang dalam ruangan untuk menyalakan pendingin ruangan

Employee Presence Using Body Temperature Detection And Face Recognition
Employee performance can be measured by their presence or attendance, which applies to both civil servants and non-civil servants. Because the attendance system still uses the manual technique, it is considered inefficient due to the potential for data fraud and attendance problems. In addition, the government is adopting precautions against viruses in office buildings to maintain business continuity while the pandemic is being addressed. This study aimed to employ a facial recognition system and temperature measurement to lower the danger of COVID 19 transmission while minimizing paper use by using a facial recognition system as a substitute for presence. It has so far permitted the digitization of formerly manual sights. The OpenCV library allows computers to detect faces using the haar cascade classifier approach and Python as a programming language. A Logitech C930e webcam with a resolution of 1080p at 30fps was used to capture facial data, which was then processed on a Raspberry Pi 4 microprocessor. It uses an MLX90614 sensor to monitor body temperature, which is controlled by an Arduino Uno microcontroller. It is well integrated into the database based on body temperature testing and facial recognition. The development of a more accurate temperature sensor reading method for distance and employee body temperature is a priority for future research
An improved electricity efficiency method based on microcontroller and IoT with infrared sensor
This paper proposes an improved electricity efficiency method using an infrared sensor and internet of things (IoT). Almost all field of human work require electrical energy, especially for household needs. The averages household has many lamps in each room, so if it is not controlled, it will be wasteful of energy. However, this work is carried out to gain a better understanding of a new method for saving energy. The main advantage of this work is the simplification of the sensor used, in which only the infrared sensor required. Although the proposed approach faces numerous challenges, it successfully provides result as parameters that it can be processed rapidly using low-cost microcontrollers. The idea is based on the microcontroller and internet implementation with infrared sensor to monitor the number of people in home to control the lamp light intensity. The idea is proven in two ways: design and experiment. In this paper, the implementation of Raspberry Pi and Arduino is created to monitor the number of people in room and control the lamp intensity through internet or web. Arduino uses for the sensor processing and Raspberry Pi as server. The web is used to display the monitoring result by retrieving data from database that created using MySQL. The result indicates that the electricity bill decreased between 7.7-8.2% over 2 months implementation. The conclusion of this study suggests that the research in this area could be directed toward to be used in saving electricity usage in human life, especially for household

Development of a Simple and Low-cost Smartphone Gimbal with MPU-6050 Sensor
This paper discusses about design and development of gimbal smartphone, which are made to be simple and less money consuming by utilizing microcontroller and MPU 6050 sensor. Recently, the development of videography and image processing is inseparable from the rapid advance in smartphone technology. One of the most popular features is camera. Hand movements and shocks cause fewer maximum results. To improve the quality of camera captures and video, it is necessary to have a stabilizer for camera position. Thus, it is expected that the outcomes of this paper are able to give contribution for cheap gimbal smartphone. Design and implementation of gimbal uses acrylic as the material, with 5 mm of thickness. This MPU 6050 sensor is optimized to detect sway in axis X, Y, and Z or roll, pitch, and yaw. Gyroscope and accelerometer provide input to the microcontroller, which will process for output on 3 servomotors that function to maintain the camera’s position at a specified set point. The results show that MPU 6050 sensor can response angle reading error of 1.34° of roll, 0.25° of pitch, and 0.78° of yaw. Error in maximum servomotor movement is 1.5°. Thus, it can be concluded that gimbal can work optimally with less money consuming as well as low error. It is expected that the next research will add other suitable and accurate control, that is, PID or fuzzy
Implementasi DFPlayer untuk Al-Qur’an Digital berbasis Mikrokontroler ESP32
Modul DFPlayer biasa digunakan untuk aplikasi suara, seperti alarm, bel sekolah atau aplikasi yang tidak membutuhkan pengelolahan file mp3 yang banyak. Namun dengan metode yang tepat, DFPlayer juga dapat mengelola file mp3 Al-Quran yang berjumlah 6236 buah dengan baik. Artikel ini akan menunjukkan salah satu metode untuk membaca file mp3 Al-Qur’an sehingga seluruh ayat-ayat Al-Qur’an dapat dilantunkan. Metode tersebut adalah menyusun dan mengurutkan nama file mp3 pada folder MP3, membuat algoritma konversi nama urutan file mp3 dan algoritma pemutaran mp3 berdasarkan rentang ayat secara berurutan. Perangkat ini dirancang dengan memanfaatkan mikrokontroler ESP32 sebagai unit pengontrol utama, modul DFPlayer sebagai dekoder audio dan aplikasi Android sebagai pemilih surah dan ayat yang akan diputar. Hasil pengujian yang didapatkan bahwa pemutaran surah pada juz 30 dan pemutaran rentang ayat pada seluruh surah berhasil 100%.Modul DFPlayer biasa digunakan untuk aplikasi suara, seperti alarm, bel sekolah atau aplikasi yang tidak membutuhkan pengelolahan file mp3 yang banyak.
