Hi @ttt
There are some limits to the grove TDS sensor.

  • The Waterproof TDS probe cannot be used in water above 70°C.
  • The sensor cannot be used to measure flowing water.
  • The sensor cannot be used to measure water with high pollution concentration.
  • The Grove sensor itself is not waterproof.
    What kind of TDS meter were you used? It is normal if the value of ppm is not too different.
