Abstract

Prototype of PDAM Water Flow Measurement and IoT-Based Automatic Filtration is an intelligent system designed to automatically monitor and filter PDAM (Regional Drinking Water Company) water in a household environment. This system uses a turbidity sensor installed on the pipe to measure the clarity and height of the water in real-time. When the water flow exceeds a certain limit, the filtration process will begin. The development of this tool began with direct observation of housing residents and boarding house residents to identify common clean water problems. Based on the results of these observations, the system was designed using main components such as turbidity sensors, ultrasonic sensors, DC (Direct Current) pumps, servo motors, and NodeMCU ESP32 microcontrollers. In the testing phase, the PDAM pipe was connected to the prototype and observations were made on the sensor response. The turbidity sensor is used to check the clarity of the water twice, namely before and after the filtration process. The data results are sent in real-time to the Blynk application via an IoT (Internet Of Thing) connection with NodeMCU ESP32. The application displays information in the form of NTU (Nephelometric Turbidity Unit) values for water clarity, water level in the reservoir, and overall clarity status. Data received from the sensor in the form of analog signals is converted into voltage, then the turbidity level is calculated based on the calibration value. The system uses if-else logic to determine water conditions and regulate servo movements based on ultrasonic sensor readings. The results of the data obtained are when <100 NTU, the water is identified as clear and when the water in the reservoir reaches a distance of <10 cm as measured using an ultrasonic sensor, the servo will open automatically. However, when the turbidity sensor detects that the water clarity level reaches >100 NTU, the pump will turn on to return the water in the reservoir back to the storage reservoir for re-filtering. The prototype developed by this researcher is effective in detecting the clarity of PDAM water and has the potential to support efforts to preserve water quality in settlements, as well as increase public awareness of the importance of clean water that is suitable for consumption.
