DFRobot Gravity Analogue TDS Sensor Water Purity Meter

The Gravity: Analog TDS Sensor / Meter for Arduino allows for the measurement of the TDS value using a TDS pen, indicating how many soluble solids are dissolved in one liter of water and serving as an indicator of water purity. Unlike expensive professional TDS meters, this device is a cost-effective alternative for measuring TDS values. The meter is waterproof, making it ideal for applications in water quality analysis and hydroponics.

Features:
Good compatibility: Output 0–2.3 V analog signal output, compatible with 5 V or 3.3 V controllers.
AC excitation source: effectively prevents probe polarization.
Waterproof probe.
Easy to use: Arduino-compatible, simple connection, plug and play without soldering.
