Development of Aquarium Auto Cleaning System

Abstract

The thesis describes entire process in development of aquarium auto cleaning system. It is a system that been designed to ease fish keeper from their duty to change the water of an aquarium. The system will automatically detect the turbidity of water and do the process of change the water in the aquarium. This system is a combination of two sensors; turbidity sensor and water level sensor. Turbidity sensor been designed by water running through in between LDR and LED. While for the water level sensor the designed is based on ADC concept where the detection of voltage at two points; low level and high level is the sensor part itself. All the hardware and software development been integrated by Arduino based. In analysis phase for software development there are several issues regarding ADC for high level sensor such as, the unstable value when measurement is taken. All procedure to undertake and minimize the problem been made for the solution to the problem. Starting with the problem been analyzed and the requirement for the solution been obtained until the solution been designed. The thesis will describe the entire process step-by-step and how-to approach the problem occurs.
