TDS single channel sensor module

TDS (Total Dissolved Solids) is a measure of the combined total of organic and inorganic substances contained in water. It can be a general indicator of water quality. The unit of TDS measurement is ppm or milligrams per liter (mg/L). The larger the TDS value, the more dissolved substances in water.

By cooperation with the corresponding circuit, it can detect the conductivity (TDS value) of purified water. Installs quickly and easily, no leaks, long life.

With this sensor module, you can DIY a TDS tester to easily check the cleanliness of the water.

The commonly used TDS testing equipment is a TDS pen. Although it is inexpensive and easy to use, it cannot transmit data to the control system, do long-term online monitoring, and analyze the water quality. Using a special instrument, although the data can be transmitted, the accuracy is high, but the price is very expensive. To this end, we have specially introduced this Arduino-compatible TDS sensor, which can be used to measure the TDS value of water after connecting to the Arduino controller.
