Rancang Bangun Mesin Pengisian Air Mineral Otomatis Berbasis Arduino Nano dengan Sensor Berat Load Cell 1 Kg

Abstract

Technological advancements have driven the creation of automation systems capable of improving efficiency and accuracy across various sectors, including liquid filling processes such as mineral water. This study aims to design and develop an automatic mineral water filling machine based on an Arduino Nano microcontroller and a 1 kg Load cell weight sensor. The system is designed to accurately detect the weight of water and automatically stop the filling process once the target is reached, accompanied by an audible warning. The machine is specifically intended for small-scale home industries and operates based on a weight target measured in grams. Implementation results show that the system effectively automates the filling process, reduces manual filling errors, and enhances production efficiency. Testing indicates that the average filling error remains within acceptable tolerance limits. For future development, the system could be improved by adding pump speed control, remote monitoring, coin sensor integration for automated payment, and regular calibration to maintain sensor accuracy.
