This is an Arduino-compatible TDS Sensor Kit for measuring Total dissolved solids value of the water. TDS indicates how many milligrams of soluble solids dissolved in one litre of water. In general, the higher the TDS value, the more soluble solids dissolved in water, and the less clean the water is. Therefore, the TDS value can be used as one of the references for reflecting the cleanliness of water.
This TDS Sensor kit supports 3.3 ~ 5.5V voltage input, and 0 ~ 2.3V analog voltage output, which makes it compatible with most 5V or 3.3V controller such as Arduino and ESP32.
