Automated wireless flood warning system in remote areas

During a natural calamity, it is almost impossible to reach out to people and alert them. In order to reach out and communicate to more people during floods, an idea to create a safety device, which measures the water level in the water body and alerts people if the level crosses the set threshold level, is being developed. A sensor is placed in the water body at the threshold level. If the level increases and is about to reach the threshold level, the device (raspberry pi) in the control room is indicated by the sensor. This will help people in evacuating more efficiently even in crucial times. The device will be a vital tool as well as a ray of hope to the people in difficult times.
