IoT + Solar Built for Filipino rice farmers

Never guess your soil moisture & water level again.

SAGIPfarmer is a solar-powered IoT system that reads your rice field's water level and soil moisture in real time — and sends it straight to your Android phone. Know exactly when to irrigate, when to drain, and when to save water.

Key Features

Everything you need to manage your rice field's water

Purpose-built for the realities of rice farming — low power, long range, and readable under the sun.

Real-Time Water Level

Ultrasonic sensors measure the exact water depth in your paddies every few minutes — no more walking the bunds to check.

Soil Moisture Sensing

Capacitive probes buried at root depth track moisture percentage, so you irrigate based on the soil — not on habit.

Solar-Powered Node

A small solar panel and rechargeable battery keep the field node running continuously — no wiring, no electric bill.

Smart Threshold Alerts

Set your own minimum and maximum water levels. Get an instant push notification the moment readings go out of range.

History & Trends

Daily, weekly and seasonal graphs show how water and moisture behave — useful for planning the next cropping cycle.

ESP Module

ESP-based Wi-Fi provides wireless connectivity between the field node and the local network, enabling reliable data transmission within the available Wi-Fi range.

How It Works

From the paddy to your pocket in four steps

No technical background required. Install the node, open the app, and start reading your field.

1

Install the Node

Mount the solar-powered sensor node at the edge of your field and push the probes into the soil.

2

Sensors Collect Data

Water level and soil moisture are sampled automatically and continuously, day and night.

3

Data Goes Wireless

Readings travel over a long-range low-power link to the gateway, then up to the database.

4

Read It on Your Phone

Open the SAGIPfarmer app to see live values, trends, and alerts — anywhere you have a signal.

The System

Low-cost hardware, built to survive the field

Every component was chosen for durability, low power draw, and availability in local electronics markets — so the system stays affordable and repairable.

Ultrasonic Water Level Sensor

Non-contact measurement from above the water surface — no corrosion, no clogging with mud or algae.

Capacitive Soil Moisture Probe

Corrosion-resistant sensing at root depth, giving stable readings across a full cropping season.

Microcontroller + LoRa Module

Handles sampling and transmits data over long distances with very little power consumption.

Solar Panel + Li-ion Battery

Charges through the day and keeps the node alive overnight and through cloudy weather.

Data Flow

How a single reading travels from your paddy to your screen.

Why It Matters

Save water, save fuel, save the harvest

Water management is the single biggest controllable factor in rice yield. SAGIPfarmer makes it measurable.

↓ 25%

Less Water Wasted

Irrigate only when the field actually needs it, instead of flooding on a fixed schedule.

↓ 30%

Lower Pumping Cost

Fewer unnecessary pumping hours means less diesel, less electricity, and less wear on equipment.

↑ Yield

Healthier Rice Growth

Maintaining the correct water depth at each growth stage supports tillering and grain filling.

0 km

No More Field Rounds

Check every plot from home. Stop walking the bunds at dawn just to read a water gauge.

24/7

Catches Night Problems

Breaches and sudden drainage happen at night too. Alerts reach you before the damage spreads.

∞

Free Sunlight

Solar power means the node works in fields far from any electrical connection — and costs nothing to run.

FAQ

Common questions

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.
