Arduino Tds Sensor Module Water Quality Sensor For Arduino V1.0 amplification transistor and LS688 are totem poleTDS Meter V1. 0 Module Water Quality Sensor for Arduino TDS sensor kit is compatible with Arduino controllers, plug and play, easy to use. It can be applied to measure TDS value of the water, to reflect the cleanliness of the water. TDS (Total Dissolved Solids) indicates that how many milligrams of soluble solids dissolved in one liter of water. In general, the higher the TDS value, the more soluble solids dissolved in water, and the less clean the
