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
- 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

Product description
The Gravity: Analog TDS Sensor is an Arduino-compatible TDS Meter Kit for measuring the TDS value of the water to reflect the cleanliness of the water. It can be applied to domestic water, hydroponics, and other fields of water quality testing. TDS (Total Dissolved Solids) indicates how many milligrams of soluble solids are dissolved in one liter of water. In general, the higher the TDS value, the more soluble solids are 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. The commonly used TDS detection device is a TDS pen. Although it is inexpensive and easy to use, it cannot transmit data to the control system for long-term online monitoring and water quality analysis. Using specialized instruments, although data can be transmitted and accuracy is high, the price is expensive. Therefore, we have specifically developed this Arduino compatible TDS sensor, which can be connected to an Arduino controller to measure the TDS value of water. FEATURES Specifically designed for Arduino with gravity interface, making wiring simple, plug-and-play, and no soldering required.
Easy and convenient to use. The TDS probe is waterproof and can be submerged in water for long-term measurements. This TDS sensor has a wide voltage supply of 3.3 ~ 5.5V and an analog signal output of 0~ 2.3V, making this product compatible with 5V and 3.3V control systems, and easily integrated into existing control systems. The excitation source for measurement uses an AC signal, effectively preventing probe polarization, prolonging probe lifespan, and increasing output signal stability. Board Overview 1 - Power GND (0V) 2 + Power VCC( 3.3 ~ 5.5V ) 3 A Analog Signal Output(0 ~ 2.3V ) 4 TDS TDS Probe Connector 5 LED
Power Indicator Attention: The probe cannot be used in water above 55 degrees Celsius. The probe cannot be left too close to the edge of the container; otherwise, it will affect the reading. The head and the cable of the probe are waterproof, but the connector and the signal transmitter board are not waterproof. Please be careful. Connection Diagram FAQ Q1. Does this sensor have a temperature sensor? How to make the temperature compensation? A1. This TDS probe has no temperature sensor, but the temperature compensation algorithm is reserved in the sample code. The temperature variable in the sample code will default to 25 °C without a temperature sensor. You can add a waterproof temperature sensor to read the temperature, then update the temperature variable, to make automatic temperature compensation.
