Abstract

An excessive flow of water in a water system for example a lake or river is frequently the cause of flooding. Flooding because of sewage overflow and chemical spills can cause a number of health problems besides leading to the lack of essentials and damage to homes, offices, and other facilities. The risk of electrocution when electrical equipment comes into touch with floodwater should not be ignored. The NodeMCU ESP8266 microcontroller, water level sensor, a relay and an instant alarm will all be used in this system in nearby villages to warn the appropriate authorities and rapidly send information about potential floods. The process for the output starts when there is no flood detected and the Green LED will turns on. When the water level sensor detect flood at the maximum level, the sensors transmit data to the Blynk application through ESP8266. The sensors receives a signal, the buzzer and red LED will functioning while the relay will cut off main power supply and the bulb will turn off. When the maximum water level not triggered, the relay can manually turn on by using Blynk application to power on the bulb. The system also predicts how long it would take for a flood to reach them, giving people an opportunity of time to escape
