Ultrasonic module, servo motor, arduino uno, UART, arduino IDE, MATLAB.Abstract
It is very difficult to measure the underwater position of target/object. Further, GPS can not used in
underwater, because satellite signals are not worked in underwater. Also the accuracy of position measurement is
greatly affected by many factors of the underwater environment. By considering the facts, this research experiment is
overcome the problem, the main aim of this system is use GPS on the sea surface, Which is mounted on the node. Due
to the use of GPS , we known the position of node on the sea surface. Calculate the distance of the object/target by use
of ultrasonic module
