As the flow changes the coastal terrain, it might cause unexpected rip currents, and people often get into the area because of the calm surface, which causes drowning accidents.
RCA can be installed on the security line of the water area. The ultrasonic flow velocity sensor is used to detect the water flow velocity. When the general velocity exceeds 0.6m~2m / sec, it will be judged as a rip current. The floating plate above the RCA will turn red and alert the tourists and lifeguards, letting lifeguards make appropriate disposals. When a tourist is pushed outward by the rip current, they can also hold on to the red board to wait for rescue.
