Sistem Kontrol Suhu pada Industri Ruangan Ikan Salai Menggunakan Internet of Things (IoT)

Abstract

Fish smoking is a preservation method used to enhance shelf life and improve the flavor quality of fish. However, traditional smoking methods still face several limitations, such as dependence on firewood and weather conditions. This research aims to design and test an automatic temperature control system based on the Internet of Things (IoT) using the ESP32 microcontroller and DS18B20 temperature sensor. The system includes temperature setting via a potentiometer and data display through an LCD screen and an Android application built with MIT App Inventor. The system was tested at temperatures of 35°C, 40°C, 45°C, 50°C, and 55°C. The results show that the tool successfully maintains the set temperature with minimal deviation and accurately displays real-time temperature data on both the LCD and the mobile application. The control system can automatically operate the heater and fan based on the current room temperature. Furthermore, the system reduces reliance on firewood and allows for remote operation, making it more environmentally friendly and efficient.
