This is a SeeedStudio Grove TDS Sensor/Meter For Water Quality. The Grove – TDS Sensor detects the Total Dissolved Solids (TDS) levels in the water which can be used to indicate the water quality. The Grove – TDS Sensor can be applied in water quality applications such as TDS meter, well water, aquarium, hydroponics, etc. It supports 3.3/5V input voltage and 0 ~ 2.3V Output Voltage making it easy to be compatible with all Arduino Boards. The sensor also provides a waterproof probe, making the testing process much easier to handle.
