Monitoring and Warning of Flooding Conditions Using IoT Based System

Floods pose a significant threat to both human lives and infrastructure, necessitating the development of efficient flood detection and alerting systems. In this project, we propose an Internet of Things (IoT)-based solution for flood detection and alerting, employing Arduino as the central control unit interfaced with various sensors including a flow sensor, raindrop sensor, GSM module, and ultrasonic sensor. The system's primary objective is to monitor the water level of a river, enabling early flood detection and timely alert generation to mitigate potential damages.

The flow sensor, integrated into the system, measures the flow rate of the river water, providing vital information about its volume. The raindrop sensor detects the intensity of rainfall, aiding in assessing the potential for flood occurrence. Meanwhile, the ultrasonic sensor is utilized to measure the distance between the sensor and the water surface, providing water level measurements. By combining the data from these sensors, a comprehensive understanding of the river's water level dynamics can be achieved. The Arduino acts as the central processing unit, collecting sensor data and analysing it in. Based on predefined thresholds and flood detection, the system determines if the water level exceeds a critical point, indicating an impending flood. When such a situation arises, the GSM module is utilized to send alert messages to predetermined emergency contacts, enabling prompt response and evacuation measures.
