Natural disasters occur annually as well as unpredictably, causing the nation to suffer insecurity, interruption, and economic loss. It is estimated that floods cause more economic damage and loss of life and property than any other natural hazard. The main objective of this project is to provide an early warning to flood victims at a place that is highly susceptible to flooding. Through the use of the Internet of Things technology, the victim could get accurate data on the flood in real time. It develops a real-time flood monitoring and early warning system for flood-prone areas using wireless sensor nodes. The system is based on NodeMCU technology integrated with Blynk. During a flood or heavy rain, the wireless sensor node can provide an early warning by detecting water levels and rain intensity. Sensor nodes are placed at flood areas and are equipped with ultrasonic sensors and rain sensors controlled by NodeMCUs as microcontrollers. Buzzers and LEDs are activated and alert the victim when the flood has reached a certain level of hazard. The Blynk application receives sensor data via wireless connection from the sensors. The victim will get to know the status of flood and rain by viewing the interface and receiving a push notification. This is available in the Blynk application via IOS or Android smartphones.
