PERANCANGAN BAK MANDI BAYI MENGGUNAKAN SISTEM OTOMATIS DAN PENGENDALI SUHU AIR BERBASIS ARDUINO MEGA 2560

The aim of this study was to develop and evaluate a fully automated baby bathtub system that features water level and temperature control using an Arduino Mega 2560 microcontroller. The intention of this system is to offer a secure and comfortable bathing environment for infants while providing convenience for parents. The methodology involved designing the system using components, such as a 4x4 keypad, relays, water level sensors, and temperature sensors, followed by extensive testing to ensure proper functionality and accuracy. The results showed that the system successfully maintained the water level at a maximum of 9 liters and controlled the water temperature within a narrow range of the setpoint, with minor discrepancies of 0.5°C to 1.0°C due to the natural delay in temperature mixing. The total operation time for preparing the bathtub, including heating and filling, ranged from 15 to 20 minutes, demonstrating its efficiency. All components performed accurately during testing, verifying the system's dependability. In summary, the automated baby bathtub system effectively achieves its design objectives, providing a secure, efficient, and user-friendly solution for infant bathing, and instilling confidence in parents regarding its safety and ease of use.
