Estimating Water Conductivity and TDS with Arduino

Estimate conductivity-derived TDS trends with temperature compensation and calibration; TDS alone cannot determine whether water is safe to drink.

Engineering approach

Estimate conductivity-derived TDS trends with temperature compensation and calibration; TDS alone cannot determine whether water is safe to drink.

Implementation guidance

Use an AC-excited conductivity front end intended for water, calibrate with conductivity standards, measure temperature, and convert to TDS only with a documented factor appropriate to the solution.

Scope and limitations

Conductivity cannot reveal which ions, pathogens, organics, or toxic contaminants are present. Potability requires appropriate laboratory testing and local standards.
