Monitoring and Warning of Flooding Conditions Using IoT Based System

To be sure, flooding is one of the most devastating natural calamities that needs to be addressed. It has widespread repercussions for the economy and has caused many deaths. Lack of warning causes a great deal of annual mortality. This study employed the NodeMCU, ultrasonic sensors, and other sensors to detect and measure the depths of flood waters. Here, we measure changes in the river's level with the help of an ultrasonic HC-SR04 sensor and a NodeMCU ESP8266 Microcontroller. The information after processing will be sent to the ThingSpeak IoT Cloud Platform. With this method, river levels may be tracked graphically from any location. The circuit's software was programmed using the Arduino IDE and uploaded to the Arduino microcontroller's memory. The study concluded that the proposed sensor could precisely determine the location of an incoming object and present that information as a distance on the ThingSpeak Cloud Platform. Concurrently, the sensor shows off LED indicators for your eyes to feast over. Based on data from an Arduino Uno, this system uses the Internet of Things to issue warnings to the proper authorities ahead of time of any impending floods.
