Okay but sensitive
It works, but the readings fluctuate a bit if the wiring is long. Keep wires short.

No more corrosion!
Finally a sensor that doesn't rust away in a week. Highly recommended for automation.

Perfect for my garden project
Works exactly as described. Much better than the resistive ones that corrode quickly.

Good quality but needs calibration
The sensor is well built. You need to calibrate it for your specific soil type though.

Great for ESP32
Connected easily to my ESP32. Readings are stable and consistent.
5 FAQ
Q: Can I get a digital output from this?
A: This specific module provides analog output. You would need a comparator circuit or microcontroller to convert it.
Q: Is this compatible with 3.3V logic?
A: Yes, this module operates between 3.3V and 5V DC.
Q: Does it come with a library for Arduino?
A: We provide example code in the description, but it works with standard analog read functions.
Q: What is the difference between this and resistive sensors?
A: Capacitive sensors measure dielectric permittivity and do not suffer from electrolytic corrosion like resistive sensors.
Q: How deep can I bury this sensor?
A: The probe section is designed to be inserted into soil, but avoid submerging the electronics components.
