Good sensor, needs calibration
Accurate readings after I calibrated it with a standard solution. Out of the box it was slightly off but expected for this price point.

Documentation unclear
Had trouble finding the right library for ESP32 initially. Once working it is fine, but more examples would help.

Excellent build quality
Probe feels durable and the module board is well soldered. No issues with corrosion after a week in the tank.

Fast response time
Monitoring my aquarium and the temperature updates quickly. TDS readings match my handheld tester closely.
Q: What power supply do you recommend?
A: A stable 5V 1A power supply is recommended to ensure consistent sensor readings and avoid noise.
Q: Do I need a calibration solution?
A: Calibration is recommended for precise measurements. You can use standard TDS calibration powder or solution.
Q: Is the module board itself waterproof?
A: The probe is waterproof submersible, but the module board should be kept dry or housed in a protective enclosure.
Q: Can I extend the probe cable?
A: The standard length is 1.5 meters. Extending it may cause signal loss, so we recommend keeping the original length.
Q: Is this compatible with Raspberry Pi GPIO?
A: Yes, it uses UART communication. Ensure you connect the TX/RX lines correctly and use 3.3V logic levels.
