Smart Flood Monitoring & Alert System

Flash floods often strike without warning because many high-risk areas lack the basic sensors needed to track rising water levels at critical river and drainage points. To solve this, we developed the Smart Flood Monitoring and Alert System, a low-cost IoT prototype designed to give residents and authorities the early information they need to stay safe. The system is built around an ESP32 microcontroller and a water level sensor that provides continuous, real-time data collection. The "brain" of the system classifies risk into three distinct stages: NORMAL, AMARAN (Warning), and BANJIR (Flood). When a threat is detected, it triggers a multi-layered alert mechanism combining an on-site OLED display, local sirens and LED signals with instant Telegram notifications sent directly to users' smartphones. Testing confirmed that the prototype successfully maintains Wi-Fi connectivity to deliver precise water-level alerts regardless of the user's location. This project demonstrates a reliable and scalable solution for bridging the communication gap in disaster management, providing a practical tool to enhance community resilience in flood-prone areas
