Abstract: This research paper is for designing and implementation of a flood monitoring system that could be used individually or as a sensor unit in the flood monitoring network. In recent years, natural disaster, specifically flash flood frequently affects major property damage and taken many lives, due to the inattentiveness of flood level as it rise rapidly in the flood prone area. A real-time alert flood monitoring system equipped with wide communication range and warns locals to be the solution for this problem will act as a crucial component that can prevent the inattentiveness during heavy rainstorm season.
