Good value but needs calibration
The sensor reads consistently, but you must calibrate it with a known solution for accurate ppm readings. Good for relative measurements.

Robust build quality
The probe feels sturdy and the cable is long enough for my tank setup. Signal is stable.

Perfect for thesis work
Used this for monitoring hydroponics. Data logging was easy with an ESP32. Highly recommend.

Solid sensor module
Arrived quickly. The analog output is smooth. Just remember it's not laboratory grade, but great for hobbyists.
Q: Is this waterproof?
A: The probe is waterproof, but the PCB module should not be submerged.
Q: What is the accuracy margin?
A: Typically within ±10% depending on calibration and water temperature. We recommend using a temperature sensor for compensation.
Q: Is there a library available?
A: Yes, there are several open-source libraries available on GitHub compatible with Arduino IDE.
Q: Does it come with calibration powder?
A: No, the module does not include calibration solution. You will need to purchase TDS calibration powder separately.
Q: Can I use this with 3.3V logic?
A: Yes, the module supports input voltage from 3.3V to 5.5V, making it compatible with 3.3V microcontrollers.
