Abstract

Flooding is a disaster that requires a fast and easily accessible monitoring and early warning system. This study aims to design and develop an Android-based flood early warning system using ESP32 and an HC-SR04 ultrasonic sensor. The research employed a Research and Development (R&D) method with a prototyping approach, consisting of system requirements analysis, design, implementation, and testing. The HC-SR04 sensor was used to detect water levels, while the ESP32 processed the sensor data and transmitted it via Wi-Fi to an Android application. The system also employed a buzzer as a local warning indicator when the water level reached a predetermined threshold. The test results showed that the system was able to detect changes in water levels, determine the water status based on predefined thresholds, activate the buzzer, and transmit information to the Android application in real time. The developed system can serve as an alternative solution for flood monitoring and early warning, enabling users to receive timely information and take appropriate mitigation measures.
