A Waterproof Ultrasonic Sensing System For Locating Fish In Underwater Area

Abstract

A waterproof ultrasonic sensing system for locating fish using geometric analysis of the position of the fish against the observer. The prototype is a system designed to detect fish and sea depth, the system is integrated with a smartphone hence fish location coordinates can be determined. The system uses sensors ultrasonic waterproof, namely transducer sensor with waterproof specially designed to work under water with the frquency of 200 KHz. The system uses Arduino MEGA2560 as the central performance control system by an additional HC-05 Bluetooth Shield that enables Arduino MEGA2560 communicate with Android smartphones. Android 2.3 smartphone use a GPS device that is connected directly with Google Maps and as an additional display for monitoring the presence of fish and the depth of the sea.The system is designed using the C Arduino programming language and JAVA Android. The experimental results showed the prototype system detects the presence of fish with an accuracy of 84%, and the measurement of ocean depths by percentage error ranges from 5.5% and the smartphone can display the fish  location coordinates.
