Arsitektur Remote Sistem Pemberi Pakan Ikan Berbasis Mikrokontroler Wemos D1 dan ESP32CAM

Abstract

During the Covid-19 pandemic, many people are active at home and many develop hobbies that have a high selling value. Activities during the COVID-19 pandemic are undeniably more and more busy for some people. Various activities are increasingly diverse, often the feeding of ornamental fish becomes forgotten and uncontrolled so that many fish die. In this study, it is proposed to design a remote architecture of a fish feeder system based on Wemos D1 and ESP32Cam microcontrollers that are integrated with the telegram application. Different from previous research, this research uses Arduino Uno Wemos D1 and ESP32Cam based on the Internet of Things. The advantage is that it can feed fish remotely which is controlled using the telegram application. This study uses the Research and Development (R&D) method. The reason for choosing the R&D method is because this method can be used to produce and test the effectiveness of a particular product, develop a new product, or improve an existing product, and there are detailed process steps or algorithms. The response speed of sending notifications by the speed of a network, if the network is very fast, it only takes about 1 second to send the notification.

Sistem Presensi dengan Fitur RFID dan Capture Citra menggunakan NodeMCU dan ESP32-Cam

“…Ketika sensor mendeteksi gerakan maka ESP32-Cam secara otomatis mengambil gambar yang hasilnya dikirim kepada pemilik rumah melalui aplikasi LINE yang sudah diuji dan mendapatkan hasil pengujian bahwa alat 100% dapat berjalan dengan baik (Wicaksono & Rahmatya, 2020). Hal tersebut membuktikan bahwa ESP32-Cam dapat digunakan untuk mengambil citra serta memprosesnya untuk dikirim hasilnya menggunakan jaringan internet (Duma & Joyo, 2021). ESP32-Cam dapat digunakan pada sistem presensi untuk meningkatkan validasi data berupa bukti foto agar mengantisipasi kecurangan yang dapat dilakukan oleh peserta presensi.…”

Task collection monitoring system on lockers with notifications on Telegram

“…The DS3231 RTC module generally has an electrical signal produced by the receiving sensor depending on the distance of the object to be detected and the quality of the transmitter sensor and receiver sensor [11]. Selenoids are electrical components that can convert electrical energy into mechanical energy or movement so that solenoids are called electromagnetic devices [9]. The way this selenoid works is that when current flows through the wire in the selenoid system, around the wire will produce a magnetic field.…”
