Water Level Monitoring and Flood Alerting by Applying IoT

A flood is a natural disaster that causes problems in many aspects, resulting in subsequent losses. Thailand can reduce flood impact with an early warning system, allowing time for prevention. This project was created to develop a flood warning system according to the early warning system project of the Department of Water Resources. The project emphasizes informing local residents to better understand the situation and more quickly assess solutions and responses. By installing the water level measuring units at the point near the people's residence, the people can choose to install it themselves, which can transmit the data from the base to the main control unit that monitors the house of the residents in that area by applying ultrasonic sensors and rain detection modules that are controlled by a microcontroller. There is a multi-channel notification system, both light and sound notifications. Displaying messages on the LCD screen and notifications via the Line application. The remote control also uses the Blynk application to reset the main control station and all three bases. Including having a ThingSpeak data recording system to analyze the situation and later cut off power within the households. The results of the experiment can show good notifications.
