PENENTUAN KUALITAS AIR LIMBAH RUMAH TANGGA BERBASIS SENSOR DISSOLVED OXYGEN (DO) DAN TOTAL DISSOLVED SOLIDS (TDS) MENGGUNAKAN METODE FUZZY
Manual monitoring of household wastewater quality is inefficient and slow. This research aims to design a real-time monitoring system based on the NodeMCU ESP32 using Dissolved Oxygen (DO), Total Dissolved Solids (TDS), and Temperature sensors. The Fuzzy Logic method is used to determine the water quality classification (Very Good, Good, Moderate, Poor, Very Poor). The theoretical ideal model (Fuzzy Sugeno) is implemented on the microcontroller as an efficient Rule-Based System (3D Array) with 27 rules. Test results show the system successfully reads sensor data accurately and classifies wastewater samples. Comparative analysis proves the Implemented Model is a valid approximation of the Ideal Model. Furthermore, the system successfully sent all monitoring data to Google Sheets for remote logging.
