Operating at 5V and 11mA, it features an adjustable sensitivity potentiometer and works reliably between -30°C and 80°C. Designed for partial immersion, it’s perfect for environmental monitoring, wastewater analysis, and lab research, empowering professionals to track water clarity with real-time data. ## Description Note: The sensor is not water-proof; can only place the transparent part into water. Be careful not to reversely connect the power supply, or the sensor will be damaged. You can turn the blue potentiometer on the sensor to adjust the sensitivity of sensor. The function of the potentiometer is to change the electrical signal read, and it cannot change the output voltage. Turbidity sensors can be used in measurement of water quality in rivers and streams, wastewater and effluent measurements, sediment transport research and laboratory measurements. Specification: Operating Voltage: DC 5V Operating Current: about 11mA Detection Range: 0%--3.5%（0-4550NTU） Operating Temperature: -30℃~80℃ Storage Temperature：-10℃~80℃ Error Range: ±0.5%F*S Package List: 1 * Turbidity Sensor Module Review: Very cool little sensor - I saw before I bought it that I couldn't submerge it, so I'm not knocking a star off for that. I think it could be sealed with hot glue, but my guess is that the sensor generates enough heat which might generate condensation. The sensor itself is fantastic and tells you how "clear" the water is. I used example code that D. Porrey posted (Thanks D!) and was up and running quickly. I bought this, along with the TDS sensor to measure the contaminates of my water in my laser cutter cooling system. These two together seem to be a great combo since the readings are consistent and instant. They will tell me when my water is starting to look not so fresh, since it's in a place where I can't see it without some effort. I hooked this up to an arduino and sent the data to Node Red so I have a digital gauge showing my water condition on the phone. Review: Nice but not waterproof - Turbidity vs concentration follows a cubic fit over an extended range, which is convenient. The main issue is that, as noted, the meter is NOT waterproof. It would be nice to have the option to pay more and have that feature! ## Features - The turbidity sensor for arduino can detect the water quality by measuring the level of turbidity - The principle is to convert the current signal into the voltage output through the circuit. The lower the output voltage is, the higher the turbidity value. - Its detection range is 0%-3.5% (0-4550NTU) , with an error range of ±05%F*S. - Do not completely immerse the sensor in water. Just measure the small round head of the split parts into the water and measure it. The top of probe is not waterproof. - How to use: search for "keyestudio wiki ks0414" in Google Chrome to get the wiki online tutorial for this product. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #1,996 in Single Board Computers (Computers & Accessories) | | Customer Reviews | 3.9 out of 5 stars 36 Reviews | ## Images ![KEYESTUDIO Turbidity Sensor Module V1 for Arduino,Water Quality Monitor Particles Water/Liquid Turbidity Level Tester - Image 1](https://m.media-amazon.com/images/I/51YusnJoRhL.jpg) ## Questions & Answers **Q: What wires are +5v, 0v, and signal out?** A: Red is 5v, black is ground, and yellow is data! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very cool little sensor *by D***R on August 7, 2020* I saw before I bought it that I couldn't submerge it, so I'm not knocking a star off for that.

The main issue is that, as noted, the meter is NOT waterproof. It would be nice to have the option to pay more and have that feature! ### ⭐⭐⭐ Sensor is not completely waterproof *by X***A on February 16, 2024* I originally bought this sensor to use inside my fishtank in order to evaluate the quality of the water. The sensor works great, and I am able to receive readings consistent with test strips. However, the sensor part of this product is not completely water proof. This feels counterintuitive, but I ended up fixing it to a piece of foam as to keep the correct part in the water. ## Frequently Bought Together - 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. - Teyleten Robot PH Value Data Detection and Acquisition Sensor Module Acidity and Alkalinity Sensor Monitoring and Control ph0-14 for Arduino --- ## 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.hr/products/146991089-keyestudio-turbidity-sensor-module-v1-for-arduino-water-quality-monitor](https://www.desertcart.hr/products/146991089-keyestudio-turbidity-sensor-module-v1-for-arduino-water-quality-monitor) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-12*
