Perfect for my hydroponic setup
This TDS sensor module works flawlessly with my Arduino Uno. The analog output is stable, and the calibration process was straightforward using the provided library examples. Great value for hobbyists.

Good accuracy after calibration
Initially, the readings were a bit off, but after calibrating with standard solutions, it matches my handheld meter closely. Just remember to keep the probe clean for best results.

Reliable and durable
Been running this in my nutrient reservoir for three months now. No corrosion on the probes, and the readings help me maintain optimal plant health. Excellent purchase.

Easy to integrate
The PH2.0 connector makes wiring very clean. I used this for a smart aquarium monitor project, and the data consistency is impressive. Highly recommended for DIY electronics.

Great for learning projects
Bought this for a university water quality project. It's robust enough for repeated testing in the lab. The only downside is the cable could be slightly longer for some tank setups.

Works well but needs careful handling
The sensor is sensitive and accurate, but the probe tip is somewhat fragile. Make sure not to hit it against the container walls. Once set up correctly, it performs as expected.
Q: What library should I use for Arduino?
A: You can use generic analog read functions, but we recommend searching for 'TDS Sensor' in the Arduino Library Manager for dedicated libraries that handle temperature compensation and averaging.
Q: Is this sensor waterproof?
A: The probe head is waterproof and designed for submersion in liquid. However, the circuit board module itself is not waterproof and should be kept dry or housed in an enclosure.
Q: Can I use this with a 3.3V microcontroller?
A: Yes, the module supports an operating voltage range of 3.3V to 5.5V, making it fully compatible with 3.3V boards like the ESP32 or Raspberry Pi.
Q: How often does the probe need replacement?
A: Under normal usage and proper cleaning, the probe can last 6 to 12 months. Lifespan depends on the conductivity of the liquid and frequency of use.
Q: Does this come with calibration powder?
A: No, this package includes only the sensor module and probe. Calibration solutions (standard TDS liquids) must be purchased separately to ensure accurate readings.
