Abstract: A digital salinometer has been designed. This study aims to design a salinity level measuring instrument with an electrode sensor based on the ATmega 328 microcontroller. In addition to designing tools, this study also aims to find out the work system of measuring instruments and the accuracy of the measurement results of salinity measurement tools based on the ATmega 328 microcontroller. The salinity value obtained by measuring the voltage of the difference in resistance in the sample is then converted in salinity. The main processor of this tool uses the ATmega328 microcontroller which is programmed using Arduino IDE software and a detection sensor in the form of an electrode sensor. The results of the salinity values obtained will be displayed on the 16x2 LCD.
