Easy to integrate

Plug and play with standard microcontrollers. The corrosion-resistant coating gives me peace of mind leaving it in the soil permanently. No more digging up rusty probes every season.

Best value for money

For the price, you cannot beat the durability. The wide voltage operation means I can use it on both 3.3V and 5V logic boards without level shifters. A must-have for smart gardening.

Great for automated watering systems

Works perfectly with my ESP32 setup. The wide voltage range is a huge plus. I deducted one star only because the wire could be a bit longer for larger pots, but otherwise excellent quality.

Accurate and durable

The analog output is very linear, making calibration easy. I compared it against a professional meter and the results were spot on. Highly recommended for any serious hydroponics or soil project.

Solid performance

Very reliable sensor. It handles the moisture fluctuations in my greenhouse well. The build quality feels premium compared to cheaper alternatives I've tried before.

Finally, a sensor that doesn't rust!

I've gone through so many resistive sensors that corroded within weeks. This capacitive model has been in my tomato planter for three months now and still looks brand new. The readings are stable and consistent.

5 FAQ

Q: Does this require any special libraries for Arduino?

A: No special libraries are required. Since it outputs an analog signal, you can simply read the value using the standard analogRead() function in your Arduino sketch.

Q: Will this work in salty soil conditions?

A: While the sensor is corrosion-resistant, extremely high salinity can affect capacitive readings. It is designed for typical garden and potting soils, but we recommend testing in your specific environment for critical applications.

Q: How long is the included wire?

A: The package includes a connection wire that is approximately 20cm (about 8 inches) long, which is sufficient for most standard pot sizes.

Q: Is this sensor waterproof or just water-resistant?

A: The sensor probe features a corrosion-resistant coating suitable for direct soil contact and high humidity, but the electronic module itself should be kept dry or housed in a waterproof enclosure.

Q: Can I use this with a 3.3V Arduino Pro Mini?

A: Yes, absolutely. This sensor supports a wide voltage operation range from 3.3V to 5.5V, making it fully compatible with 3.3V microcontrollers like the Arduino Pro Mini.
