Soil Meter

SoilMeter turns your Android phone into a powerful, real-time soil analysis dashboard. Just connect your USB soil meter and instantly read every value your sensor reports — no internet, no account, and no complicated setup. Everything runs directly on your device.

Built for both of the most popular meter types:

• 7-in-1 soil meters (USB-HID)

• 8-in-1 soil meters (serial / Modbus RTU)

Pick your model once on first launch and SoilMeter handles the rest. It auto-detects your meter, connects automatically, and reconnects on its own if the cable is bumped or briefly unplugged — so you spend your time testing soil, not fighting with connections.

WHAT YOU CAN MEASURE

Depending on your meter model, SoilMeter reads and displays:

• Soil moisture (%)

• Soil temperature

• pH level (acidity / alkalinity)

• Nitrogen (N)

• Phosphorus (P)

• Potassium (K)

• Electrical conductivity (EC)

• Salinity

• Soil fertility (calculated from N, P and K)

KEY FEATURES

• Live readings — every value updates in real time as you insert the probe into the soil

• Reading history — your past measurements are saved automatically and shown in a clear, easy-to-read chart so you can track changes over time

• Fertility insight — an at-a-glance fertility value calculated from your nitrogen, phosphorus and potassium readings

• Wrong-meter detection — if you plug in a different model than the one you selected, the app tells you immediately instead of showing confusing results

• Automatic reconnect — pull the cable or bump the connector and SoilMeter quietly reconnects and keeps reading

• Guided tour — a quick, friendly walkthrough the first time you open the app

• Simple settings — switch meter type, replay the tour, or rate the app any time

• Fully offline — all processing happens on your phone; nothing is uploaded

• No ads, no sign-up, no tracking, no data collection

HOW IT WORKS

1. Connect your USB soil meter to your phone (a USB-OTG adapter may be required)

2. Grant USB permission when Android prompts you

3. Select your meter model — 7-in-1 or 8-in-1

4. Push the probe into the soil and watch your results appear live

WHO IT'S FOR

• Home gardeners and hobby growers checking their beds and pots

• Farmers and agronomists monitoring field conditions

• Greenhouses, nurseries and indoor grows

• Students and teachers exploring soil science

• Anyone who owns a USB soil meter and wants a clear, reliable readout instead of a tiny built-in display

WHY SOILMETER

Many USB soil meters ship with cramped screens or clunky software. SoilMeter gives you a clean, modern, full-screen view of all your sensor's data, keeps a running history, and works entirely on your phone with no internet required. It's private by design — your readings never leave your device.

REQUIREMENTS

• An Android phone with USB host (OTG) support

• A compatible 7-in-1 (USB-HID) or 8-in-1 (serial / Modbus) USB soil meter

• A USB-OTG adapter or cable, depending on your phone and meter

Connect your meter, probe the soil, and read your results — it's that simple. SoilMeter is the dependable, private companion your soil sensor deserves.
