The project introduces an IoT-based flood monitoring system using Arduino Uno, soil moisture sensor, LCD, buzzer, Wi-Fi module (e.g., ESP8266), and ThingSpeak cloud platform. It monitors soil moisture levels, issuing alerts when a predefined threshold indicative of potential flooding is reached. The soil moisture sensor measures moisture content and is displayed on an LCD screen for real-time monitoring. A buzzer provides audible alerts for high moisture levels. A Wi-Fi module enables wireless communication, transmitting data to the ThingSpeak cloud platform for centralized storage and analysis. Users access real-time and historical data through ThingSpeak's interface. The system configures the Wi-Fi module to connect to a network, securely sending data using a unique API key. ThingSpeak enables visualization, analysis, and alert setup based on soil moisture levels, offering a comprehensive flood monitoring solution. This cost-effective system, integrating open-source hardware and cloud platforms, enhances accessibility and deployment ease and is suitable for various environmental monitoring applications.
