Automatic lifebuoy

Automatic life buoy is a new type of life buoy designed by students of Zhengzhou University. It can automatically find the location of the person who accidentally fell into the water and drive past to rescue the person who fell into the water in the first time. Put the life buoy in the water, turn on the power, and the life buoy will be able to sense the person falling into the water within 10 meters. It can save a certain amount of time for the rescue of those who fell into the water and liberate part of the rescue manpower.
