Project Idea
Develop an IoT-based smart flood monitoring system that continuously monitors water levels in rivers, drainage systems, or flood-prone areas and sends real-time alerts to authorities and residents. The system ensures early warning and proactive disaster management through cloud-based monitoring and smartphone notifications.
Project Description
The IoT-Based Smart Flood Monitoring System uses an ultrasonic water level sensor connected to a NodeMCU microcontroller to measure rising water levels. The data is transmitted in real-time to a cloud platform (Blynk,) via Wi-Fi. When water levels exceed safe thresholds, the system triggers instant alerts via Blynk Ap. The system can also log historical data to analyze flood patterns. This project is ideal for government bodies, disaster management agencies, and community flood monitoring initiatives.
