However, to ensure the availability of safe drinking water for consumption, the quality needs to be monitored periodically. Poor water quality will cause adverse health effects. Based on PERMENKES number 416 of 1990 on the requirements and supervision of clean water quality has a pH level of 6.5 to 9.0. In monitoring the water quality periodically it is necessary to design and develop the system. Making this tool uses an Arduino as a micro-controller by using C language. Some sensors are used to measure water chemical parameters, parameters measured such as pH and turbidity. The sensor will measure the processed value of Arduino which is the core controller. The results will be saved to the server to facilitate data collection and data processing. The results of the data can be seen in web monitoring as the final result of data processing.idTeknik InformatikaInformatikaInternet of ThingsDetectorThesis
