Design and Construction of Early flood warning system through SMS based on SIM300C GSM modem

Design and Construction of Early flood warning system is focused on an accurate measurement of water threshold height and send a warning message to the clients. The system was designed to have the capability to predict the remaining time before the flood and also detect three types of water level: early flood level, flood level and low tide level after the flood. Also supported by GSM modem, the measured data will then be sent via SMS (Short Message Service) to two specific clients´ phone numbers that have previously been inputted into the system. This system will send warning message three times each time it detect conditions of: prone to flooding, flooding, and safe condition. In order to protect the system and empowering the measurement, it is designed using PVC pipe. The research shown that the system can detect as far as 3 meters distance when placed inside an 8 inches PVC pipe. This system is designed to work for 24 hours and it also has additional features such as water level measurement request to determine the current level of water. Flood early warning system is a stand-alone system, making it easier to be placed at flood prone spots. The setting for client phone numbers and the water level can be programmed by sending the SMS which has been formatted in the system.
