What are Depth Sensors?

Ocean going ships typically use depth sensing techniques mainly for locating underwater objects to prevent running into them. This included gauging the distance of the sea floor. The principle involves measuring the time a burst of sound directed into the water takes to return after reflecting off an object. This time of flight gives a measure of its distance from the source of the sound, as the speed of sound traveling in water is fairly constant, depending on the water density and its temperature.
