Abstract

This paper demonstrates the design process, implementation and experimental verification of an SMS based Flood Monitoring and Early Warning system. With tools such as credit top-up and storing contact numbers will be done via SMS. Updates on the height of the water level would be texted upon users’ request. The system provides timely information and alerts at-risk or threatened populace and relevant authorities by means of SMS when the level of water surpasses the user defined threshold value. The Global System for Mobile Communications (GSM) module is used for sending the mobile text messages while the Arduino Uno microprocessor is used to read in the input from the pressure sensor and then calculate the height of water. This simple yet effective warning system is deemed to be one of the fastest and cost effective method of alerting the relevant authorities and the vulnerable residence.
