The primary benefit of remote sensors is the smart intelligent predictive real-time stormwater management monitoring (SISWM2), which automatically recognises and detects rising water levels and notifies locals of impending flooding. The goal of the study was to determine how adding sensors to green infrastructure (GI) may reduce stormwater rise in urban areas. The problems connected with stormwater runoff from infrastructure, such as habitat destruction and river siltation, call for monitoring. The primary purpose of an early warning system for flash flood control due to rapidly increasing stormwater is to notify residents of the possibility of impending floods. Technology advancements are required to safeguard people's lives and property, which is why some towns have installed flood prediction sensor networks.
