This paper demonstrates the design process, implementation and experimental verification of a Flood Level Monitoring system. The main objective of the proposed system is to be able to read the water level at every second, display it to the supervisor and alert the affected populace and relevant authorities by means of an alarm and short message system (SMS) when the level of water surpasses a user defined threshold. The Global System for Mobile Communications (GSM) network has been used for sending the mobile messages. The Peripheral Interface Controller (PIC) microprocessor is used to read in the inputs from the sensor and then display the result. The measuring system is based upon the theory of pressure being applied to liquids. In addition, the collated data is useful to the meteorologists for investigating and monitoring the cause of flooding with respect to time and weather patterns in flood-prone areas worldwide. This early warning system is deemed to be a faster method of alerting the relevant authorities and the vulnerable residence and hence minimize physical and economic losses.
