Real Time Flood Monitoring and Notification System Using IOT

Floods can be very dangerous and cause serious damage to people and property.To help give early warnings,a real-time flood monitoring system can be made using IoT and the ESP32 microcontroller.This system uses different sensors like water level sensors,flow sensors,and rain gauges to collect live data from rivers,reservoirs,or areas that often flood.The ESP32 processes this data and sends it to a cloud server through Wi-Fi for analysis.The system also has an alert feature that can send warnings through SMS,email,or mobile app notifications to authorities and residents.The system also includes a simple web dashboard for remote monitoring. The use of IoT will allow for continuous data acquisition, low power monitoring, and real-time decision making. The ESP32 will act as a central processing unit to gather data from the sensors and send it to the cloud platform through Wi-Fi. Real-time data visualization will take place through a web-based dashboard or a mobile app, with access for both authorities and residents to monitor flooding remotely. A notification alerting the appropriate authorities or residents will be sent automatically via SMS when water level thresholds are reached for each water level sensor.
