Stable Readings

Very consistent output signal. I am using it for a hydroponics monitoring project and it hasn't failed yet.

STM32 Compatible

Connected easily to my STM32 board. The analog output is clean and easy to read with ADC.

Solid Build

Probe feels durable and the PCB is well made. Just wish the cable was a bit longer out of the box.

Great for Aquaponics

Used this for my home setup and it works perfectly with my Arduino Uno. Readings are stable after calibration.

Good Value

Works well but needs calibration before first use. Documentation could be better but overall satisfied.

5 FAQ

Q: Can I extend the probe wire?

A: Yes, you can extend the wire up to 1 meter using shielded cable to prevent signal interference.

Q: What is the maximum input voltage?

A: Please do not exceed 5.5V DC input to avoid damaging the module. 3.3V to 5V is recommended.

Q: Is there a library available for Arduino?

A: Yes, there are several open-source libraries available on GitHub compatible with this analog sensor module.

Q: Do you provide calibration solution?

A: The module does not come with solution. We recommend using a standard 1413ppm TDS calibration solution for best accuracy.

Q: Is the entire module waterproof?

A: Only the probe tip is designed for submersion. The PCB board should be kept dry or housed in a waterproof enclosure.
