Perfect for automation projects
Integrated this into my ESP32 based automatic watering system. The analog output is smooth and allows for precise moisture threshold setting. Highly recommended for IoT hobbyists.

Reliable and durable
The build quality is excellent. The gold plating really does prevent oxidation. My indoor plants have never been happier since I automated their care with this sensor.

Finally a sensor that doesn't rust!
I've tried resistive sensors before and they corroded within weeks. This capacitive module has been in my tomato planter for two months with no signs of degradation. The readings are stable and easy to calibrate.

Great value, easy to wire
Works perfectly with my Arduino Uno. The gravity connector makes wiring foolproof. I deducted one star because the documentation could be more detailed on calibration steps, but online tutorials filled the gap.

Good sensitivity range
The potentiometer allows you to fine-tune the digital output trigger easily. It reacts quickly to changes in soil moisture. Just make sure to waterproof your connections if using outdoors.

Best upgrade for my garden kit
Replaced my old sensors with these. The difference in longevity is night and day. No more digging up rusty probes every season. Simple, effective, and affordable.
Q: Does the package include the water pump for the automatic system?
A: No, this package contains only the soil moisture detection module. You will need to source a water pump and relay module separately to complete an automatic watering system.
Q: Is this compatible with 3.3V logic boards like ESP8266?
A: Yes, the module operates comfortably between 3.3V and 5.0V, making it fully compatible with ESP8266, ESP32, and standard 5V Arduinos.
Q: Can this sensor be used directly in salty soil?
A: While the capacitive design is corrosion-resistant, highly saline soil can affect reading accuracy. We recommend calibrating the sensor specifically for your soil type before deployment.
Q: How deep should I insert the sensor into the pot?
A: For best results, insert the sensor vertically until the prongs are fully submerged in the root zone, typically about 2/3rds of the probe length, avoiding the very bottom of the pot.
Q: What is the expected lifespan of the probe?
A: Due to the nickel-plated gold surface and capacitive technology, the probe is designed to last several years under normal conditions, significantly outperforming resistive sensors.
