Floods are natural disasters that can damage and endanger human life, often occurring suddenly and disrupting community activities due to a significant increase in water discharge. Changes in water levels are usually monitored at dams or floodgates using conventional measuring instruments such as rulers, so a more effective monitoring system is needed. This research aims to design and develop a flood early detection system using the VL53L1X sensor based on SMS Gateway, which is able to detect water levels and rainfall in real-time and send notifications when potential flooding is detected. This research uses the ADDIE method including Analysis, Design, Development, Implementation, and Evaluation. The test results show that the system successfully detects water levels and rainfall and provides notifications via SMS. In the first test, the water level reached 29.8 cm with 19.25 mm of rainfall, categorized as safe. In the second test, the water level increased to 59.9 cm with 45 mm of rainfall, triggering an alert warning, while in the third test, the water level reached 81.5 cm with 47.75 mm of rainfall, categorized as danger. In alert and danger conditions, the system successfully sent SMS notifications with an average delay of 3 seconds. Overall, the system functions well and is able to provide early warning of potential flooding.
