Water is a substance that is important in life after air if it has been polluted by chemicals it is very dangerous for living things. The development of the industry uses chemicals in a production that causes hazardous waste, even though it has been reprocessed in the filtering process, if it is less than perfect, the water will be polluted if disposed of in the river flow. Identification and monitoring measures are needed that require media to use a device that includes a sensor containing the pH of water that comes from the content of acidic substances in water, turbidity or the content of solid objects in the water, and water temperature. The data collection method uses a nodeMCU microcontroller. Then the data is sent via a wireless connection to be stored on the database server. Testing to see the results of monitoring using an Android application that is connected to the server. From the results, it can be concluded that the data displayed on the application can run smoothly, the value displayed can be seen in real-Time. © Published under licence by IOP Publishing Ltd.
