Flood Alert Detection System using IoT

Floods are one of the most common and devastating natural disasters, often resulting in loss of life
and property. This project presents an Io T-based Flood Alert Detection System using a NodeMCU ESP8266 micro
controller, a float switch sensor, and the Blynk IoT platform. The system is designed to detect rising water levels in
real-time and provide instant alerts to users.A float switch is used to sense the water level. When the water reaches
a critical point, the switch triggers the NodeMCU to activate local alerts using a buzzer or LED. Simultaneously,
the system sends notifications to the user's smartphone via the Blynk app over Wi-Fi. The Blynk platform also
provides a user-friendly interface to monitor the water status remotely.This solution is low-cost, energy-efficient,
and can be deployed in flood-prone areas to give early warnings and help in disaster preparedness. It demonstrates
the potential of IoT in environmental monitoring and safety systems.
