No more dead plants!
I integrated this into a smart watering system for my indoor herbs. It triggers the pump perfectly when the soil gets too dry. Highly recommend for any DIY smart home project.

Solid performance
Good sensitivity and quick response. The digital output pin is handy if you don't need precise analog values and just want a simple on/off trigger for a relay.

Robust build quality
The PCB is well-made and the connector fits snugly. I appreciate that it uses a capacitive method so the probe doesn't electrolyze over time. Excellent component for student projects too.

Best sensor in this price range
I bought five of these for a large planter box project. All of them performed consistently. The corrosion resistance is the key feature here; my old sensors died in a week.

Perfect for my automated garden
This capacitive sensor is a huge upgrade from the resistive ones I used before. No corrosion after three weeks of constant use in the soil. The readings are stable and easy to calibrate with my Arduino.

Great value, minor calibration needed
Works exactly as described. You do need to spend a few minutes calibrating the dry and wet values in your code, but once set, it's very accurate. The gold plating looks durable.
Q: How deep should I insert the sensor into the soil?
A: For best results, insert the sensor vertically until the two prongs are fully submerged in the soil area you wish to monitor. Avoid touching the bottom of the pot with the tip of the sensor.
Q: Can I connect this directly to a 3.3V ESP32?
A: Yes, this module operates on a voltage range of 3.3V to 5V, making it fully compatible with 3.3V logic boards like the ESP32 and ESP8266 without needing a level shifter.
Q: What is the difference between AO and DO pins?
A: AO (Analog Output) provides a continuous voltage value proportional to the moisture level for precise reading. DO (Digital Output) sends a HIGH/LOW signal based on a threshold you set via the onboard potentiometer.
Q: Does this come with example code for Arduino?
A: While the package includes the hardware, you can find extensive open-source example libraries and code snippets for Arduino on GitHub and our product wiki page linked in the manual.
Q: Is this sensor waterproof or just water-resistant?
A: The sensing probe is designed to be buried in soil and handles moisture well, but the electronic components on the top PCB are not waterproof. We recommend coating the electronics with conformal coating or placing them in a waterproof enclosure if used outdoors.
