Among the numerous natural disasters, floods is an overflow of water that can destroy many lives and society. It occurs mainly due to heavy rainfall and dam overflow. It affects in highly manner to people's lives and area; hence government would end up spending more resources to recover the affected region. Therefore it becomes crucial to develop a flood detection system that spreads awareness to the society about the rise in water level to potential flooded region. The system is designed with the help of raspberry pi and different sensors that play an important role in gathering timely information from water sensor unit. The Way2SMS API is used for sending alert message to the people that also helps in delivering messages in the case of no internet connectivity. Calling feature is also developed that notify people in case of flood emergency at night. The objective of the project is to design a system that can measure the rise in the water level and take water flow readings with the help of water level sensor and water flow sensor and then effectively spread the information to the society such that the necessary actions can be taken at the early stage. Thus the efficiency of the system helps in preventing materialistic as well as human loss by sending early alert information.
