Clean water is the main need of living things, especially humans. The importance of water for human life is reflected in the increase in water consumption. However, so far the use of water has not been reflected in the public awareness of water conservation, even the people are less aware of the importance of water resources, and how much water they use per day. To help PDAM customers save water and easily determine the pH of the water they use, it will be accessible through the website. Research Objectives In developing this tool, the author designed a prototype of a water meter and water PH monitoring tool using a Nodemcu-based (Internet of Things), and automatically displays the results on the LCD and the Internet. The system adopts the prototype method as a system development and system analysis method which can easily check and monitor the monthly water usage and water PH value from the website in real time, and improve the overall system to be more sophisticated. Components for problem solving Identifying and evaluating problems arising from anticipated requirements To test a prototype system that identifies and evaluates problems arising from anticipated requirements, researchers use the black box method to test equipment. This provides a benchmark for experimenting with results created using web models and equipment sensors.
