Ubiquitous Sensing for Environmental Health
This research pioneers portable, accessible water quality monitoring for mobile and field applications. By adapting NIR spectroscopy to consumer imaging hardware, it lays the groundwork for IoT-enabled, real-time water quality monitoring in smart cities and diverse environmental sensing applications. This empowers everyday users with critical data, addressing challenges of public health and environmental safety.
AI-Powered pH Prediction with Advanced Neural Networks
The core of this solution lies in an attention-based neural network (DEiT architecture) combined with a pre-trained object detection model (Faster R-CNN). This pipeline first accurately locates water containers and then focuses on relevant water surface features, achieving 85.8% classification accuracy. Interpretabilty analyses with Grad-CAM confirm the model's focus on pH-sensitive spectral features, making the system robust to variable conditions.
Non-Invasive Water pH Sensing via Near-Infrared Imaging
Traditional pH detection is contact-dependent. This work introduces a non-invasive alternative by measuring how NIR light (700-1000nm) interacts with molecular vibrations in water. Water's O-H bond vibrations are sensitive to changes in hydrogen bonding, which are influenced by pH levels. By capturing diffuse reflectance images, the system overcomes the bulkiness and environmental sensitivity of conventional NIRS, making it practical for real-world deployments.

Future Vision: Broadening Real-World Impact
While this study establishes feasibility, future work includes expanding the training dataset to encompass varying turbidity, dissolved solids, and organic matter concentrations. Integration of scattering correction techniques and multivariate calibration methods will further isolate pH-specific spectral features from interference. Extending the spectral range beyond 720-1000nm will capture additional pH-sensitive absorption bands for complex water matrices, paving the way for truly robust, widely deployable water quality monitoring systems.
