Never guess your soil moisture & water level again.

No. The field node runs entirely on its own solar panel and battery. Data is sent over a long-range low-power wireless link to a gateway, which is the only part that needs an internet connection. This means the sensors can be placed far from any power line or Wi-Fi router.

The ultrasonic water level sensor is accurate to within roughly ±1 cm under normal field conditions, and the capacitive soil moisture probe gives stable relative readings across the season. Both are calibrated before deployment so the numbers in the app match what you would measure manually.

Tap the Download APK button, then open the downloaded file from your notification bar or Files app. Android will ask you to allow installation from this source — enable it, tap Install, and the app will appear on your home screen. Since it is installed outside the Play Store, you may see a standard "unknown app" prompt, which is normal.

Yes. You can register several nodes and switch between plots from the dashboard. Each plot keeps its own thresholds, history, and alert settings, so a farmer managing multiple paddies can see everything in one place.

The node keeps measuring and the gateway stores readings locally. Once the connection returns, the buffered data is uploaded automatically, so there are no gaps in your history. The app also caches the last known readings so you can still view them offline.

The electronics enclosure is IP65-rated and mounted above the expected flood line, with sealed cable glands. The soil probe is buried and the ultrasonic sensor is non-contact, which removes the two most common failure points in wet-field instrumentation.
