IoT-Based Monitoring and Prediction of Water Quality Using Swin-Transformer and Depthwise Separable Convolutional Neural Network Optimized by Circulatory System-Based Optimization.

The degradation of water quality, one of the major global environmental challenges, demands advanced and intelligent monitoring and prediction systems. This study uses data from the Rohri Canal in the Pakistani city of SBA to develop a combined IoT-based advanced deep learning (DL) model that can accurately forecast the water quality index (WQI) and water quality class (WQC). The sensors that are used under IoT are turbidity, temperature, pH, and total dissolved solids (TDS) to measure real-time parameters of water quality. All the acquired data are preprocessed with the help of a quality-aware fuzzy min-max neural network (QAFMMN) to reduce noise efficiently and increase the quality of the data. A combination of the addax optimization algorithm and the Nadam optimizer (AOA-NO) is used to select features, keeping only the most important ones, which makes the method computationally efficient. In this regard, the model known as the Swin-Transformer-depthwise separable convolutional neural network, trained with the circulatory system-based optimization method (ST-DSCNN-CSBO), is established. Indeed, one can see the incredible results of the proposed experimental research because the R
