Accurate readings
Calibration was easy using the potentiometer. Helps me know exactly when to water my tomatoes automatically.

Finally no corrosion!
Switched from the resistive version. This one lasts much longer in the soil without degrading. Highly recommend for long-term projects.

Good value
Does what it says on the tin. Packaging was secure. Took a day to arrive. Good addition to my sensor kit.

Great sensor, short cable
Works perfectly with my ESP32. Readings are stable. Wish the cable was a bit longer for large pots, but I can extend it.
Q: Is this analog or digital output?
A: It provides an analog voltage output proportional to moisture levels.
Q: Is the probe fully waterproof?
A: The probe is IP67 rated, but the connector should be kept dry.
Q: Can I use this with 3.3V logic?
A: Yes, it operates comfortably between 3.3V and 5.5V.
Q: Do you provide a library?
A: Yes, check our GitHub for Arduino and Python examples.
Q: How long does it last underground?
A: Much longer than resistive sensors, typically over 1 year depending on soil acidity.
