Lawn Irrigation Controller Kit with ESP32 + LoRa
Lawn Irrigation Controller Kit with ESP32 + LoRa – Achieve Variable Rate Irrigation Through an Eight-Node Sensor Mesh
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Your lawn isn’t uniformly dry — patches vary in moisture, temperature, and health. This kit lets you deploy an eight-node LoRa sensor grid that maps soil moisture and temperature variations in real time, feeding a central ESP32 controller to tailor irrigation precisely where and when it’s needed. Reduce water waste, prevent overwatering, and cultivate a healthier turf — all with a system you build and own.
What You'll Build
A wireless mesh of eight battery-powered sensor nodes that transmit soil moisture and temperature data via LoRa to a central ESP32 hub. The hub processes the data to drive solenoid valves or relays for variable rate irrigation, displayed on a local dashboard or logged for analysis.
What You'll Learn
- Design and deploy a LoRa mesh network for field sensor data collection
- Calibrate soil moisture sensors and DS18B20 temperature probes for outdoor environments
- Build low-power Arduino Nano-based nodes with 18650 battery management
- Implement variable rate irrigation logic on ESP32 using real-time soil data

Who This Kit Is For
Ideal for B.Tech ECE/EEE and agricultural engineering students at IITs, NITs, VIT, BITS Pilani working on precision agriculture IoT projects. Also suited for Smart India Hackathon teams and agri-tech startups prototyping farm automation solutions. If you’re a maker or professional looking to deploy a wireless sensor network for lawn or small-farm irrigation, this kit gives you a head start.
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?
Our AI companion walks you through each wiring and code step; if you need human help, WhatsApp us from the QR card for direct support.
Can I extend the number of sensor nodes beyond eight?
Yes, the LoRa mesh network is scalable — the ESP32 coordinator can handle additional nodes, but you’ll need extra Arduino Nanos, sensors, and LoRa modules. The AI guide includes tips on scaling.
How do I integrate this with my existing irrigation valves?
The central ESP32 hub can control standard 12V solenoid valves via relay modules (not included), and the code examples show wiring and logic for variable rate control based on sensor data.
Is this kit suitable for outdoor deployment in all Indian climates?
Yes, we include waterproof enclosures for nodes and recommend battery recharging during monsoons; the DS18B20 probes and soil moisture sensors are rugged, and the 433MHz LoRa range works well across lawns and small farms.
Lawn — Eight-node LoRa soil moisture + temperature grid maps field heterogeneity to drive variable rate irrigation.
