Dissolved solids in water sensor TDS

Product detailed description

TDS (Total Dissolved Solids) refers to how many milligrams of dissolved solids are dissolved in 1 litre of water. In general, the higher the TDS value, the more dissolved substances there are in the water and the less pure the water is. Although TDS may not effectively reflect water quality under certain circumstances, as a parameter that can be quickly detected, TDS can still be used as a parameter to reflect effective water quality as a reference.
This product can be applied to water quality testing in home waterworks, hydroponics and other fields. With this sensor, you can easily detect water purity and control water quality.
The board allows the connection of a DS18B20 temperature sensor, so that the microcontroller can also measure water temperature.
