Measurement of TDS of Water Sample using Arduino UNO

Measurement of TDS of Water Sample using Arduino UNO – details of complete project

We know that the larger is the salinity of water the more is its electrical conductivity. So by using standard techniques of measuring the electrical conductivity (Ec) we can use this value to find out the TDS by using following empirical equation.
