I am working on a project for rescuing people drowning in water. The project is on preliminary stage. So the water should not be that rough, detection range should be around 15-20 meters. I have to detect the drowning body, a water vehical is to reach that drowning person and provide a life preserver.
Now the question is can I detect the body using a single sensor or a combination of sensors? And which sensors should I use ?
