  • Commercial turbidimeters are expensive, limiting their use in low-resource settings.
  • Effective water quality assessment is crucial for public health and sanitation.

Purpose of the Study:

  • To design and construct an affordable, open-source turbidimeter.
  • To evaluate the performance of the developed turbidimeter against a commercial standard.
  • To promote accessible water quality monitoring in underserved communities.

Main Methods:

  • Development of an open-source turbidimeter utilizing a single light-to-frequency sensor.
  • Calibration and validation of the device by comparing its measurements to a portable commercial turbidimeter.
  • Testing the instrument's performance in assessing water turbidity.

Main Results:

  • A functional and affordable open-source turbidimeter was successfully constructed.
  • The developed turbidimeter demonstrated reliable performance when evaluated against a commercial instrument.
  • The cost-effectiveness of the new device makes it suitable for low-resource applications.

Conclusions:

  • The developed open-source turbidimeter offers a viable, low-cost alternative for assessing drinking water quality.
  • This innovation can significantly improve water quality monitoring capabilities in resource-limited regions.
  • The project aims to foster further advancements in affordable water and sanitation technologies.
