Lawn Irrigation Controller Kit v9
ESP32 Lawn Irrigation Controller Kit — AI That Decides When Your Lawn Needs Water
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a lawn that tells you exactly when it needs watering — not based on a timer, but on real-time soil data. This kit turns an ESP32 into a smart irrigation controller that reads soil moisture, pH, and temperature, then uses an on-device TensorFlow Lite decision tree to decide: irrigate or stay healthy. It’s the same AI-on-the-edge logic used in precision agriculture, shrunk down to a weekend build.
What You'll Build
You’ll assemble a compact monitoring unit that probes soil conditions at the root zone. The 0.96-inch OLED displays live sensor values and the AI’s verdict. When conditions drift toward dryness, the screen shows “Irrigation Needed”; when the lawn is in the green zone, it reads “Healthy”. You’ll also get a bare-bones codebase that’s easy to extend — add a relay for automatic valve control, or push data to a cloud dashboard via Wi-Fi.
What You'll Learn
- Wiring analog and digital sensors (moisture, pH, DS18B20) to an ESP32 without signal conflicts
- Collecting and normalizing sensor data to create a labeled training dataset for a decision tree
- Training a decision tree model in Python and converting it to TensorFlow Lite for microcontrollers
- Running real-time inference on the ESP32 and displaying results with clear decision thresholds

Who This Kit Is For
Students building CBSE Class 11-12 computer science or agriculture-tech projects will find this a perfect AI-IoT integration. ATL Tinkering Labs can use it to demonstrate sensor fusion and edge inference. B.Tech ECE and EEE students preparing for Smart India Hackathon or final-year prototypes will appreciate the ready-to-extend hardware-software stack. Makers who want to automate lawn care in Indian homes without cloud dependencies will also love this self-contained solution.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Open the QR code on the box to chat with the AI build companion; it understands the exact wiring and code you’re working on. You can also send a photo on WhatsApp for direct engineer support.
Do I need a lawn to test this kit?
No, a small potted plant or even a cup of moist soil works perfectly. The sensors respond to any growing medium, so you can refine the AI model indoors before deploying outside.
Is the TensorFlow Lite model pre-loaded or do I train it myself?
You train it yourself using a guided Python notebook — the kit includes sample data and clear steps. This teaches you the full ML pipeline from data collection to on-device inference.
Can this kit control an irrigation valve automatically?
Absolutely. The ESP32 has unused GPIO pins. Connect a relay module (not included) to trigger a 12V solenoid valve when the AI outputs “Irrigation Needed”, and you have a fully automated lawn guardian.
Lawn — TFLite decision tree on ESP32 classifies soil moisture, pH and temperature into irrigation-needed or healthy states.
