【 摘 要 】

Along with the increasing use of water by the community, the quality of water needs to be considered, especially for human consumption. Water quality is determined based on the value of turbidity of water. This project develops an Arduino Uno-based water turbidity monitoring system, which is aimed to measure water level and water turbidity levels. The turbidity sensor consists of a photodiode and infrared LED. Measurements of water turbidity using principles of light scattering in the water. The turbidity sensor to detect the intensity of light passing through the scattering of particles and the results of the analog signal voltage. The signal entering Arduino Uno of the ultrasonic sensor and the turbidity sensor will be processed. The measurement results is converted to NTU (Nephelometric Turbidity Units) and liter, then are shown on the LCD display 2x16. The turbidity measurement limits on this system are designed between 0 NTU to 40 NTU. This system can potentially help PDAM in monitoring water tanks and it is hoped that water quality monitoring system can be applied online.
