IoT based Early Flood Detection, Destruction Avoidance and Automated Dam Gate Control System

The purpose of this study is to predict the flood at the dams and alerting the authorities to make them the people who are living their lives in remote areas i.e., near to the dam to the safer place, so that to reduce the mortality rate due to unprecedented flood. This study predicts the flood by using sensor-based networking system. Here, two ultrasonic sensors are connected to determine the level of water; waterflow sensor is used to know the speed of water; rainfall sensor is used to determine the rainfall. After measuring all the factors, the data is processed to the NodeMCU, which will act as a transmitter and it will transfer the data through the wireless communication to the another NodeMCU, which was situated at the office present at the dam and it will act as a receiver. After analyzing all the values, if the values exceed the limit, an alert will be sent to the authorities and then automatically the dam gates will get open.
