Good Value
Calibration takes a little time to get right, but once set up, it is quite accurate for the price point. Good addition to my water testing kit.

Fast Shipping
Arrived early and well packaged. No damage to the module or probe. Tested it immediately and it responded to changes in water conductivity instantly.

Cable Could Be Longer
Works well technically, but I needed an extension cable for my specific tank setup. The 50cm cable was just a bit short for my application.

Exact Specifications
Matches the description exactly. The build quality feels solid and the stainless steel probe seems durable for long-term immersion.

Great for Hydroponics
Works perfectly with my ESP32 setup. I am using it to monitor nutrient levels in my indoor garden. The analog output is stable and easy to read.
Q: Is the module waterproof?
A: The probe is waterproof and designed for immersion, but the circuit board module itself should be kept dry or housed in a protective enclosure.
Q: How do I calibrate the sensor?
A: Use a standard TDS calibration solution and adjust the onboard potentiometer until the analog reading matches the known value of the solution.
Q: Does this work with 5V Arduino?
A: Yes, it supports 3.3V to 5.5V input voltage, so it is fully compatible with standard 5V Arduino boards.
Q: Is a library available?
A: Yes, check our GitHub repository for sample code and libraries compatible with popular microcontrollers.
Q: Can it measure saltwater?
A: Yes, it can measure conductivity in saltwater provided the total dissolved solids remain within the 0-1000 ppm measurement range.
