PC Based Flood Warning System

Abstract

People have faced floods and other related disasters from thousand of years. Rainfall is the most effected reason for floods. So people monitored rainfalls and other climate changes. Normally meteorologists capture rainfall readings 8 times per day (once three hours) and broadcast it to the people once a day. Furthermore, there is no any system to determine the rate of rainfall (E.g. rainfall per minute). Between broadcast times, if there exceed a threshold limit of rainfall, there is no suitable way to announce it to the people. So people possibly will have to faced floods and other related disasters. If there is an automatic system to measure rainfall rate and other climate changes, then people can get away of disasters. Most research groups have made instruments for measure climate changes. But still there is no good automatic system to measure rainfall rates, announce it. So, such a system should be made. In this project we attempt to make a system for measure rainfall rate automatically and broadcast it to the nation. The system can monitor the rainfall rate and notify if it reach to a threshold limit. For work the system accurately, there are several parts attach to it. The tipping bucket is the rain water collecting and counting unit. It can measure rainfall rates. Next is the counter unit, it can count the rainfall rates. The counter unit uses a Light Emitting Diode (LED) and a Light Dependent Resister (LDR) to with the purpose of. Other part is the Analog to Digital converter, which can convert the Analogue signal generated from counter unit to Digital signal which the can inserted to PC. These signals inputted to the PC trough a port. Inside the PC the data stored and analyzed them. If exceed a threshold limit of rainfall the system automatically inform it.
