Understand the AI soil sensor: how it reads your soil and guides watering
Start with the probe in the root zone. That tip collects moisture and turns it into usable data. The detachable stem lets you place the probe deeper, where roots actually take up water.
The probe sends moisture measurements to a controller at a 1-second refresh rate with ±5% accuracy. The controller processes those readings and pushes real-time updates to the app so you know when to water or wait.
How readings map to action
Fast updates save you time. Quick refresh rates catch changes during hot afternoons or after a rain. Consistent data builds a history you can use to spot patterns across pots and beds.
Protecting roots and structure
The IP67-rated probe is sealed against liquids and dirt and designed to be gentle on roots. Deep placement gives more accurate levels for the root zone without compacting the ground.
| Element | What it reports | Why it matters |
|---|---|---|
| Probe tip | Moisture and saturation readings | Targets the zone where roots absorb water |
| Controller | Processed data and triggers | Turns measurements into on/off actions |
| App | Real-time levels and history | Alerts you and shows trends over time |
