Flood is an unescapable natural event on the world. On the other hand, it creates a huge economic damage and cause a significant loss in human life. Using different sensors, researchers made a flood level detecting device with the help of Arduino Yun. Proposed model is also useful for us in anticipating the for the coming calamities and to take essential activities by emergency and recover experts to spare the life of thousands of individuals before this basic condition happens. The Flood Detector System using Arduino is created to be one of the quickest strategies to monitor flood and Internet of Things (IoT) is one of the most important technical trends which is utilized to monitor flood and human made resources to help in predicting and detecting essential events like flood, fire, gas and water leak that can position an threats to human life.
