It supports a wide voltage range (3.3~5.5V), outputs analog signals (0~2.3V), and features a waterproof 60cm probe with XH2.54 connectors. Ideal for domestic water and hydroponics monitoring, it offers Β±10% accuracy within a 0-1000ppm range, empowering DIY enthusiasts and professionals to ensure optimal water quality. ## Description Keyestudio TDS sensor kit is compatible with Arduino controllers, plug and play, easy to use, Analog TDS Sensor for Domestic Water and Hydroponics Water Quality Monitoring Technical Parameters TDS Meter sensor: Input Voltage: DC 3.3 ~ 5.5V Output Voltage: 0 ~ 2.3V Working Current: 3 ~ 6mA TDS Measurement Range: 0 ~ 1000ppm TDS Measurement Accuracy: Β± 10% F.S. (25 ℃) Module Interface: XH2.54-3P Electrode Interface: XH2.54-2P Waterproof TDS Probe: Number of Needle: 2 Total Length: 60cm Connection Interface: XH2.54-2P Color: White Shipping List: TDS Meter V1.0 sensor for Arduino x1 Waterproof TDS Probe x1 XH2.54-3Pin Jumper Wire x1 ## Features - This TDS probe sensor for arduino is used to measure TDS value of the water. The TDS value can be used as one of the basis for reflecting the cleanliness of water. - TDS (Total Dissolved Solids): indicates how many milligrams of soluble solids dissolved in one liter of water. The higher the TDS value, the more soluble solids dissolved in water, and the less clean the water is. - This TDS Meter Probe is plug and play and easy to use. Also, the wide supply voltage of 3.3~5.5V and the analog signal output of 0~2.3V. Comes with XH2.54-2P/3P connector wires. - Its Electrode can measure conductive materials, such as suspended solids, heavy metals and conductive ions in water. Also, it can be used for water quality testing in the field of domestic water and hydroponics. - With this sensor, you can easily DIY a TDS detector, and easily check the cleanliness of the water to make your water quality better.

This meter only goes up to 1000 ppm. If the water is higher than that it won’t read it correctly **Q: Can this be left submerged permanently?** A: If you talk about the sensor itself, I would say yes. Depends a bit on the salinity of the fluid you are measuring. Sea water will destroy everything given enough time. Potable water should be OK. **Q: Can i use this sensor an esp32 board? the example code is for arduino uno** A: Yes it works just fine with an ESP 32. the example code works as well for the esp 32 **Q: Does this come with any calibration solutions or what is recommended for calibration?** A: it does not. Also, it only reads up to 1000ppm, so its ok for water quality testing, but not hydroponics nutrient solution. you can buy calibration solution on amazon ## Frequently Bought Together - KEYESTUDIO TDS Meter Probe Water Quality Monitoring V1 Sensor Module with XH2.54-3Pin Jumper Wire Connector for Arduino - KEYESTUDIO Turbidity Sensor Module V1 for Arduino,Water Quality Monitor Particles Water/Liquid Turbidity Level Tester - CQRobot TDS (Total Dissolved Solids) Meter Sensor Compatible with Raspberry Pi/Arduino Board. for Liquid Quality Analysis Teaching, Scientific Research, Laboratory, Online Analysis, etc. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/312092270-keyestudio-tds-meter-probe-water-quality-monitoring-v1-sensor-module](https://www.desertcart.sc/products/312092270-keyestudio-tds-meter-probe-water-quality-monitoring-v1-sensor-module) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-09-25*
