EXPANDED TECHNICAL DETAILS

Automated Liquid Chemical Assay Hub

This scientific instrument uses digital colorimetry to provide accurate, objective readings of aquarium water test tubes (e.g., for Nitrate, pH, or Ammonia levels).

  • RGB Photometric Spectral Analysis: Uses a high-gain RGB sensor (e.g., TCS34725). The Arduino shines a stabilized white LED through the sample test tube; the sensor captures the exact R, G, and B absorption values of the liquid.
  • Beer-Lambert Law Calibration Kernel: The firmware maps the raw color values to a chemical concentration using a pre-defined calibration curve, eliminating the human error involved in eye-balling color charts.

Design

  • 3D-Printed Light-Shield Chassis: The light-tight test-tube holder was custom-designed for 3D printing, ensuring that external ambient light does not interfere with the precision color measurement.
