Quantitative Chemical Sensing in Your Pocket
Visual colorimetric interpretation of pH strips often suffers from subjective eye fatigue, inconsistent ambient illumination, and printer variations across manufacturers. Smart_pH solves this bottleneck by combining an intuitive color-cropping interface with a deep neural network trained on multi-source RGB datasets under diverse lighting conditions.
How to Use Smart_pH
Follow this simple three-step procedure to extract quantitative pH metrics from any standard indicator paper.
Capture or Upload
Open the app and either snap a direct photo of the developed test strip using your phone's camera, or select an existing photo from your device's photo gallery.
Align Color Boxes
Easily drag and resize the intuitive bounding boxes over the reactive color pads on the strip. The system computes mean, median, and mode RGB distribution parameters.
Execute Prediction
Tap “Predict” to feed the normalized color parameters through the trained artificial neural network. Receive the precise pH value and confidence bounds instantly.
