Good accuracy, minor calibration needed

Works well out of the box but I had to calibrate the dry/wet values in my code. Solid build quality.

Great upgrade from resistive sensors

Finally a sensor that doesn't corrode after a week. Works perfectly with my ESP32 project.

No more rust!

I killed three resistive sensors before buying this. This capacitive one is still working after 2 months in soil.

Easy to use with Mixly

Plug and play. The analog readings are stable and consistent. Highly recommended for beginners.

5 FAQ

Q: Is a library required for Mixly?

A: No, you can read the analog pin directly without specific libraries.

Q: Can I leave this in the soil permanently?

A: Yes, the gold plating prevents corrosion, allowing for long-term insertion.

Q: Does it work with 3.3V logic?

A: Yes, it operates between 3.3V and 5V, making it compatible with most microcontrollers.

Q: Is this waterproof?

A: The probe is corrosion-resistant and safe for soil, but the electronics board should not be submerged.

Q: What is the output range?

A: The analog output voltage ranges from 0V to 3V depending on moisture levels.
