Easy to use with Arduino
As a beginner, I was worried about wiring this up, but the PH2.0 connector made it plug-and-play with my gravity shield. The example code on the wiki got me reading values in minutes.

Great durability, needs calibration
The build quality is excellent and the corrosion resistance is real. However, you do need to calibrate it yourself for your specific soil type to get accurate percentage values. Once calibrated, it works perfectly with my ESP32 setup.

Best value capacitive sensor
Compared to other brands, this offers the best balance of price and durability. The nickel plating really makes a difference in humid environments. My data logging has been uninterrupted for weeks.

Perfect for automated irrigation
Integrated this into my smart garden system. The analog output is smooth, and unlike older models, I don't have to replace the probe every season. Highly recommended for any long-term outdoor project.

Finally, a sensor that doesn't rust!
I've gone through three resistive sensors in the last year because they corroded within weeks. This capacitive model from DFRobot has been in my tomato planter for two months now with zero signs of degradation. The readings are stable and consistent.

Solid performance
Works exactly as described. It detects the difference between dry and wet soil very quickly. I took off one star only because the cable could be a bit longer for larger raised beds, but an extension wire solved that.
Q: Does the package include cables or just the module?
A: The package includes the sensor module and one Gravity analog cable (PH2.0-3Pin to Dupont) for easy connection to mainboards. No additional soldering is required for standard setups.
Q: What is the response time for moisture changes?
A: The sensor provides real-time analog voltage output. Changes in soil moisture are reflected almost instantly (within milliseconds), though we recommend averaging multiple readings in your code to filter out noise.
Q: How does this compare to the old resistive sensors?
A: Unlike resistive sensors that pass current through the soil (causing electrolysis and rapid corrosion), this capacitive sensor measures dielectric permittivity without exposing electrodes to the soil directly. This significantly extends the lifespan of the probe.
Q: Is this sensor waterproof for direct burial in soil?
A: Yes, the probe is designed to be buried directly in soil. The capacitive sensing area is coated to prevent corrosion and short circuits from moisture. However, the electronic components at the top should not be submerged in water.
Q: Can I connect this directly to a 3.3V microcontroller like an ESP8266?
A: Absolutely. The sensor operates within a voltage range of 3.3V to 5.5V, making it fully compatible with 3.3V logic systems like the ESP8266 and ESP32 without needing a level shifter.
