Automatic Water Clarity Monitoring and Filtration System Using Light Dependent Resistor Based on Arduino Uno

Abstract

The purpose of this research is the design of the water clarity monitoring system in the aquarium can detect the level of clarity/turbidity of water at a certain level, using Arduino Uno Microcontroller as a controlling center, and LDR (Light Dependent Resistor) as a sensor. The quality of water relating to the status of clarity during the water, increasingly clear water and the quality of the water is right. Design methodology created using a closed control system. The design results show that the tool designed to control the clarity of the water in the aquarium.
