Needs careful calibration
Works but instructions could be clearer on calibration solution. Had to look up tutorials online to get accurate readings.

Great for IoT Projects
Works well with my ESP32 setup. Calibration needed but straightforward. The analog output is stable enough for logging data.

Good for hydroponics monitoring
Using it to monitor nutrient levels in my indoor garden. Readings are consistent after calibration. Would prefer a longer cable.
Q: Can I use this with Arduino Uno?
A: Yes, it works with any board that has an analog input pin and supports 3.3V to 5V logic.
Q: How often should I calibrate?
A: We recommend calibration every few months depending on usage frequency and environment.
Q: Does it come with calibration powder?
A: No, calibration solution is sold separately. You will need a standard TDS calibration solution.
Q: What is the maximum voltage input?
A: Please do not exceed 5.5V to avoid damaging the module. 5V is the recommended standard.
Q: Is this sensor waterproof?
A: The probe is waterproof and can be submerged, but the module PCB is not. Keep the board dry.
