Sand mining using heavy equipment causes groundwater pollution in Kranggan Village, Kulon Progo. This study aimed to develop a monitoring system for measuring water quality to determine the level of groundwater pollution in that location. This Android-based well water quality monitoring system was built using the C programming language, namely Arduino IDE. Data collection methods used in the development of this system are literature study, observation, and interviews. The application development phase includes analysis, system design, implementation, and testing. This program is implemented using various sensors, pH sensors, temperature sensors, and TDS sensors, each used to measure the pH value, temperature, and the number of dissolved solids. This system is also equipped with a wifi module used to send data from the device to the application created. The process that regulates the input and output of this system uses the Arduino nano and Arduino nano shield. As the primary power source used in this system is a fixed voltage adapter. An Android-based water quality monitoring system that could display measurement results and readings. The test results show that the tools and applications could run well. There are only a few shortcomings in the appearance of the application that is less attractive. [ABSTRACT FROM AUTHOR] |
