Works well but needs frequent cleaning

The sensor works as described, but in high-mineral water, the probe gets coated quickly. You need to clean it weekly to maintain accuracy.

Easy to code for

Found plenty of sample libraries online for this module. The analog output is smooth and easy to read with basic ADC conversion.

Good accuracy after calibration

Took a little time to calibrate properly using standard solutions, but once set up, it works reliably for monitoring my aquarium water quality.

Excellent for student projects

Bought five of these for our university environmental science lab. They are affordable and provide data accurate enough for educational purposes.

Robust build quality

The titanium probe feels very durable. I've had it submerged in my nutrient tank for three weeks with no signs of corrosion or drift.

Perfect for my hydroponic setup

This sensor integrates seamlessly with my Arduino controller. The readings are consistent and match my handheld meter closely. Great value for DIY projects.

5 FAQ

Q: Is this sensor waterproof or just the probe?

A: The probe is designed for submersion in liquid, but the electronic module board itself is not waterproof and should be kept dry or housed in a protective enclosure.

Q: How long is the warranty period?

A: This product comes with a standard 12-month manufacturer warranty covering defects in materials and workmanship under normal use.

Q: What is the maximum temperature the water can be for accurate reading?

A: For optimal accuracy, the water temperature should be between 0°C and 50°C. Extreme temperatures may affect the conductivity reading slightly.

Q: Can I use this with a 3.3V microcontroller?

A: Yes, the sensor operates within a voltage range of 3.3V to 5.5V, making it fully compatible with 3.3V logic boards like the ESP32 or Raspberry Pi.

Q: Does this come with calibration powder?

A: No, the package includes the sensor module and probe only. Standard TDS calibration solutions must be purchased separately for accurate initial setup.
