Gravity: Analog TDS Sensor for Arduino Total Dissolved Solids Meter Water Quality Compatible with

Accurate Water Purity Measurement: Measures TDS levels (0-1000ppm ±10% accuracy) to monitor dissolved solids in drinking water, hydroponics, and aquariums, solving the data-logging limitations of basic TDS pens Accurate Water Purity Measurement: Measures TDS levels (0-1000ppm ±10% accuracy) to monitor dissolved solids in drinking water, hydroponics, and aquariums, solving the data-logging limitations of basic TDS pens Easy to Use: simple connection via Gravity 3-pin interface, plug and play without solderin with sample code Good compatibility: This TDS sensor supports 3.3~5.5V wide voltage input, and 0 ~ 2.3V analog voltage output, which makes it compatible with a 5V or 3.3V control system or board NOTE: While the TDS probe tip and cable are waterproof and submersible, the connection interface and signal converter board are NOT waterproof. Avoid exposing these components to water during use
