Paper Abstract

This work was aimed to develop low cost devices for clear underwater exploration combined together with visible light communication (VLC) systems. This would be a new expectation of VLC application systems in the future. The complete system consisted of transmitter and receiver parts. The transmitter is responsible for transmitting sensor information data, using light emitting diode (LED). At the receiver, a photodiode is used to receive the light signal and convert into electrical signal. The pH and temperature values are displayed on the application in smartphone with Android operating system, using Bluetooth communication systems. The VLC systems work well at the maximum distance between transmitter and receiver was 80 centimeters long, and the maximum distance of Bluetooth was 10 meters.
