The Capacitive Soil Moisture Sensor V2.0 is an analog electronic probe that reads how wet or dry your soil is, so you can water plants at the right time instead of guessing. Unlike older resistive probes, the capacitive design measures moisture without two exposed metal pins, which makes it far less prone to corrosion over time. It's a favourite for home gardeners, hobbyists, and makers building smart-irrigation, greenhouse, or potted-plant monitoring projects, and it works well in soil beds, raised planters, and hydroponic-style setups.
Key features
- Capacitive sensing technology — more durable than basic resistive probes.
- Analog output, easy to read on common microcontroller boards and dev kits.
- Version V2.0 design with a clean single-probe form factor.
- Simple to insert into soil and connect with standard jumper wiring.
- Compact size suitable for pots, planters, and garden beds.
Typical uses
- Smart-irrigation and auto-watering DIY projects.
- Monitoring moisture in indoor plants and balcony pots.
- Greenhouse, nursery, and small-farm experiments.
- Educational and hobby electronics builds.
How to choose / tips
- Insert the probe to a consistent depth near the plant roots for stable readings.
- Pair it with a controller board to trigger a pump or valve automatically.
- Keep the upper electronics above the soil line, not buried in wet earth.
- Calibrate dry vs. wet readings once in your own soil for best accuracy.
