Analog TDS Sensor Module

This is an for Arduino-compatible TDS sensor/Meter Kit for measuring TDS value of the water, to reflect the cleanliness of the water.
It can be applied to domestic water, hydroponic and other fields of water quality testing.

TDS (Total Dissolved Solids) indicates that 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.
TDS pen is a widely used equipment to measure TDS value.
The price is affordable, and it is easy to use, but it is not able to transmit data to the control system for online monitoring to do some water quality analysis.
The professional instrument has high accuracy and can send data to the control system, but the price is expensive for the ordinary people.
Features:
Good Compatibility Output: 0~2.3V analogue signal output, compatible with 5V or 3.3V controller
AC Excitation Source: effectively prevent probe from polarization
Waterproof Probe
Easy to Use: for Arduino compatible, simple connection, plug and play without soldering
Measuring the TDS value in the water is to measure the total amount of various organic or inorganic substances dissolved in water, in the unit of ppm or milligrams per liter (mg/l).
