Needs calibration
The sensor works well but requires proper calibration with standard solutions to get accurate readings. Once calibrated, it is consistent.

Probe feels fragile
The electronics work fine, but the probe casing feels a bit lightweight. Handle with care during installation in water tanks.
Q: Is this compatible with Arduino Nano?
A: Yes, this module works with any microcontroller that has an Analog-to-Digital Converter (ADC) pin, including the Arduino Nano.
Q: Where can I download the source code?
A: The link to the GitHub repository containing the source code is included in the package documentation and on the product page.
Q: Can this measure saltwater TDS?
A: This sensor is calibrated for fresh water. Reading saltwater may require specific recalibration and could affect long-term probe accuracy.
Q: What is the maximum depth the probe can be submerged?
A: The probe is designed for submersion up to 1 meter. Please ensure the cable connection point remains dry to prevent corrosion.
Q: Does the package include calibration powder?
A: No, the package includes the sensor module and probe. Calibration solutions need to be purchased separately for accurate ppm readings.
