Soil Moisture
A capacitive sensor measures exactly how wet or dry your soil is. No corrosion, no false readings — just accurate data your watering automation can act on.
Grow smarter,
not harder.
🌿 Intelligent plant care, 24/7
SproutKeeper is a smart, self-contained growing assistant that watches your plants around the clock — tracking conditions, automatically controlling devices, and alerting you the moment something needs attention.
Always-on monitoring
Sensors check soil, temperature, humidity, light, nutrients, and battery continuously — SproutKeeper never misses a change.
Soil · Hydro · Aquaponics
Three complete growing modes, each with its own automation logic. Switch modes any time from the dashboard.

What it monitors
Eyes on your garden,
around the clock.
SproutKeeper continuously tracks every condition your plants need to thrive — and takes action the moment something is off.
🌡️
Temperature & Humidity
Real-time ambient temperature and humidity readings, updated continuously. SproutKeeper knows when it's too hot, too cold, or too humid — before your plants show signs of stress.
☀️
Sunlight & Lux
Precision light level measurement in real time. Automate grow lights based on how much natural light your plants are actually receiving right now — down to the exact lux.
💧
Nutrient Levels (EC)
Electrical conductivity monitoring tracks fertilizer and salt concentration so plants stay in the nutrient sweet spot for maximum growth and health.
🔋
Battery Level
Designed for wire-free installs. SproutKeeper monitors its own battery and alerts you before it goes offline, so no plant is ever left unwatched.
📊
Live Dashboard
View all sensor readings, event history, plug status, and automation activity from any phone, tablet, or computer on your local network — no app needed.
Three growing modes
Built for every way you grow.
Whether you're growing in soil, water, or running a full aquaponics ecosystem — SproutKeeper adapts to you.
Soil / Moisture Mode
The classic way to grow. SproutKeeper monitors soil moisture and automatically triggers your watering system when things get too dry. Set your thresholds once — SproutKeeper handles it from there.
Hydroponics Mode
No soil needed. SproutKeeper runs your water pump on a fully configurable timed schedule — keeping roots oxygenated and nutrients flowing continuously, 24/7.
Aquaponics Mode
The complete ecosystem. Fish waste feeds the plants, plants clean the water for the fish. SproutKeeper manages the whole loop — pump timing, water conditions, and system health.
Smart plug automation
Automate any device.
No electrician required.
SproutKeeper controls 120V devices automatically through smart plugs — pumps, lights, fans, valves, and more. It even comes with its own plug, designed to work together perfectly right out of the box.

Activate fans or AC
Trigger any HA device the moment temperature goes out of range — fans, portable AC units, blinds, whatever you have.
Light level below 500 lx after sunrise
Switch on grow lights
Supplement natural light on cloudy days automatically — and turn lights off when natural lux recovers.
Device goes offline
