Flash Flood

A Flash Flood Protection System using a water level sensor and Arduino is a smart, real-time system designed to detect sudden rises in water levels, often associated with flash floods, and trigger early warnings to prevent loss of life and property. The core components include water level sensors for detecting and monitoring water levels in rivers, reservoirs, or vulnerable areas, an Arduino microcontroller for processing data, and an alert mechanism (like alarms or SMS notifications) to warn authorities and residents.

Key Components:

1. Water Level Sensor: This sensor measures the depth of the water. It continuously monitors changes in water levels, sending real-time data to the Arduino.
2. Arduino Microcontroller: The Arduino acts as the brain of the system. It receives data from the water level sensor and processes it to determine if a dangerous rise in water level occurs.
3. Communication Module (GSM/Bluetooth): To send alerts, this module connects the system to mobile networks or local devices.
4. Power Supply: A stable power source ensures continuous operation, especially in flood-prone areas.
5. Warning System: Alarms, lights, or SMS alerts are activated to notify people when water levels reach critical thresholds.

Working Principle:

• The water level sensor measures the height of water at set intervals. This data is transmitted to the Arduino.
• The Arduino processes the incoming water level data and compares it with predefined thresholds.
• If the water level crosses the dangerous threshold, the Arduino activates the alert system, which can include sirens, lights, or even sending SMS notifications to local authorities and residents.
• Additional sensors (like rain gauges or flow meters) can be added for more accurate flood prediction.
