Grow Smarter.
Farm Better.
smartfarm connects NodeMCU sensor nodes to an AI-powered dashboard — giving you real-time visibility over soil, air, water, and nutrients across any growing environment.
From Soil to Screen
Three simple layers turn raw environmental data into actionable growing intelligence.
Sense
NodeMCU based nodes with soil, temperature, humidity, pH and NPK sensors collect readings every 30 seconds across your growing space.
Transmit
Data streams to Firebase Realtime Database over WiFi or LoRa. Offline buffering ensures nothing is lost during connectivity gaps.
Understand
The dashboard visualises trends, fires threshold alerts, and lets you query the AI agronomist for personalized advice — anytime, anywhere.
Built for Every
Growing Environment
Most PopularPrecision Greenhouse Control
Deploy a mesh of sensors across every zone of your greenhouse. Our system tracks micro-climates row by row, automatically triggers ventilation, irrigation, and nutrient dosing — so every plant gets exactly what it needs.
High ROIOptimized Hydroponic Systems
Monitor EC, pH, dissolved oxygen, water temperature and nutrient flow rates in real time. The AI flags imbalances before they cause damage, keeping your hydroponic cycles running at peak efficiency.
Beginner FriendlySmart Indoor Plant Care
Never lose a houseplant again. Compact sensors clip right onto your pots and connect to the dashboard. Get watering reminders, light warnings, and seasonal care tips tailored to each species you grow.
ScalableLarge-Scale Field Monitoring
Solar-powered sensor nodes scatter across open fields, reporting soil moisture, temperature and rainfall back to a central hub via LoRa or WiFi. Plan irrigation runs and spot stress zones before visible damage appears.
Urban LivingCity Rooftop & Balcony Plots
Urban growers face unpredictable microclimates — wind, reflective heat, and patchy sun. Our sensors map these conditions uniquely for your space, letting you choose the right crops and maximize every square metre.

Advantages That
Change the Way You Grow
Real-Time Intelligence
Every sensor reports live. Spot crop stress, irrigation shortfalls or temperature spikes the moment they occur — not hours later during a manual inspection.
AI-Powered Decisions
Groq-accelerated LLaMA 3 analyses your farm data and delivers actionable, plain-language recommendations — from fertilizer schedules to harvest timing.
Massive Water Savings
Irrigate only when and where the soil needs it. Farms using the system report 35–52 % reductions in water use compared to schedule-based irrigation.
Early Disease Detection
Abnormal humidity + temperature combinations that favour fungal outbreaks are flagged days before visible symptoms appear, giving you time to act.
Solar & Battery Ready
Sensor nodes run on a single 18650 cell for up to 6 months, or connect a small solar panel for indefinite off-grid operation in remote fields.
Farm from Anywhere
The Firebase-backed dashboard works on any device, anywhere. Check conditions from the field, the office, or across the country.
Trusted by Farmers & Gardeners
"We cut our water bill by 42 % in the first season and haven't lost a single batch to nutrient imbalance since deploying smartfarm across our 3-acre greenhouse."
David Muigai
Head Agronomist, Nairobi Greenhouse Farms
"The pH and EC monitoring for our NFT channels is flawless. The AI detected a potassium deficiency two days before our plants showed any yellowing — that alone paid for the whole system."
Amara Osei
Hydroponic Farm Manager, Accra Urban Greens
"I manage 18 hectares of open field tomatoes. Before smartfarm I was guessing irrigation schedules. Now my soil moisture data tells me exactly when and where to run the pumps. Fuel costs are down 30 %."
James Kariuki
Commercial Farmer, Nakuru County
"Set up took less than 20 minutes on my balcony garden. The app tells me exactly when each of my 12 pots needs water, and my herbs have never been healthier. Absolute game changer for city growing."
Priya Njogu
Urban Gardener, Nairobi
"We integrated smartfarm into our vertical farm's automation stack via the Firebase API. Real-time NPK data feeds directly into our nutrient dosing pumps. Zero manual adjustments needed."
Chen Wei
CTO, VerticalRoot Technologies
"The early disease detection feature flagged high-humidity conditions in our east wing three days before a botrytis outbreak would have started. We saved an entire rose crop worth over $12,000."
