Gravity: Analog TDS Meter Sensor Kit for Arduino - 83cm Waterproof Probe with Anti-Polarization Design, 0-1000ppm ±10%, Water Quality Testing for Hydroponics/Aquarium/Home

About this item

• 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
• Anti-Polarization & Long-Last Probe: The measurement excitation source adopts an AC signal, effectively preventing probe polarization. This extends the probe's lifespan while enhancing output signal stability. The TDS probe features a waterproof design, allowing for long-term immersion in water during measurements
• 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
