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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B086GX2539 | | Best Sellers Rank | #68,320 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #13 in Conductivity Meters & Accessories #62 in Lab pH Meters | | Brand Name | DFROBOT | | Customer Reviews | 4.3 4.3 out of 5 stars (30) | | Manufacturer | DFROBOT | | Maximum Supply Voltage | 5.5 volts_of_direct_current | | Measurement Accuracy | ±10% | | Model | SEN0244 | | Number of Items | 1 | | Output Type | Analog | | Part Number | SEN0244 | | Style Name | Modern | | Unit Count | 1 Count | ## Product Details - **Brand:** DFROBOT - **Maximum Supply Voltage:** 5.5 volts_of_direct_current - **Measurement Accuracy:** ±10% - **Output Type:** Analog - **Style:** Modern ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/6192ip0BC4L.jpg) ## Frequently Bought Together - Gravity: Analog TDS Sensor for Arduino | Total Dissolved Solids Meter | Water Quality Sensor Compatible with Arduino - Gravity: Dual-Mode Turbidity Sensor for Arduino / ESP32 / STM32 / Raspberry Pi (ADC Required) | Water Quality Monitor | <500ms Response Time & 0-4000NTU Range - PH Sensor for Arduino, PH0-14 Value Detect Sensor Module + PH Electrode Probe BNC, PH Sensor UNO, PH Sensor Arduino Kit, PH Sensor Raspberry Pi Kit, by HQ&LP --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/230075013-gravity-analog-tds-meter-sensor-kit-for-arduino-83cm-waterproof](https://www.desertcart.in/products/230075013-gravity-analog-tds-meter-sensor-kit-for-arduino-83cm-waterproof) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-10-20*
