Manufacturing a water turffity measuring equipment using the AB209 module sensor based on the ATMega328 microcontroller

Abstract

The development of electronic technology in the era of globalization is very rapid. Utilizing this technology as a means to monitor water clarity, especially the condition of the water, whether it is clean or there are other materials mixed with the water (turbid), to find out optimal water conditions, optimal monitoring is needed. This research will create a system that can detect water turbidity. The tool consists of a Turbidity Sensor Module AB209 sensor, ADC, and ATMega328 microcontroller. The AB209 Turbidity Sensor Module functions to detect water turbidity. The function of the ADC is to change the amount of electrical voltage resulting from the AB209 Turbidity Sensor Module into a digital quantity which is then transmitted to the ATMega328 microcontroller to be processed into a digital display on the LCD. The results of the research are that a water turbidity measurement tool can be made with a good level of accuracy, namely 99.98%
