IoT-based river water level monitoring system using LoRa technology

Abstract

Floods are one of the most destructive natural disasters, particularly affecting rural riverbank communities with limited access to early warning systems. Existing methods, such as manual monitoring and GSM(Global System for Mobile Communications)-based solutions, are often costly, power-intensive, and unsuitable for remote deployment. The aim of this research is to design and implement a lowcost, reliable, and energy-efficient IoT-based river water level monitoring system that provides real-time monitoring and alerts. The objectives include (i) accurate measurement of river water levels, (ii) reliable long-range data communication, (iii) real-time data processing and visualization, and (iv) threshold-based alert generation for disaster preparedness.
