SMS flood alert system

Flood disaster is considered a norm for Malaysians since Malaysia is located near the Equator. Flood disaster usually happens due to improper irrigation method in a housing area or the sudden increase of water volume in a river. Flood disaster often causes lost of property, damages and life. Since this disaster is considered dangerous to human life, an efficient countermeasure or alert system must be implemented in order to notify people in the early stage so that safety precautions can be taken to avoid any mishaps. This paper presents a remote water level alarm system developed by applying liquid sensors and GSM technology. System focuses on monitoring water level remotely and utilizes Global System of Mobile Connections (GSM) and Short Message Service (SMS) to convey data from sensors to the respective users through their mobile phone. The hardware of the system includes Micro Controller Unit (MCU) PIC18F452, three (3) liquid sensors, Inverter and Easygate GSM Module. Software used for the system is C compiler thru (ATtention) AT commands. It is hoped that this project would be beneficial to the community and would act as a precautionary measure in case of flood disaster at any flood prone area. By having early detection, users could take swift action such as evacuation so that cases of loss of lives could be minimized.
