Smart Garden Watering Kit v3
Smart Garden Watering Kit v3: Build a LoRa-Powered Soil Monitoring Dashboard with ESP32 & Arduino
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit empowers you to deploy eight wireless soil sensor nodes across a garden or small farm, transmitting moisture, temperature, and GPS coordinates back to an ESP32 gateway. Using a LoRa network, you'll build a real-time dashboard that overlays crop health data on a map - ideal for precision agriculture, research plots, or smart farming experiments.
What You'll Build
You'll build an 8-node LoRa sensor network with a central gateway that displays live sensor data on a web dashboard. The system maps each node's position and overlays moisture and temperature readings as colour-coded health zones, helping you optimise watering schedules and detect dry spots before plants suffer.
What You'll Learn
- Design and deploy a LoRa mesh network using RA-02 modules and 433MHz antennas
- Program ESP32 and Arduino Nano boards to read DS18B20 temperature probes and soil moisture sensors
- Build a real-time dashboard with GPS mapping and crop health overlays using MQTT and a web interface
- Integrate solar-powered battery management with TP4056 charging circuits and 18650 cells for off-grid field deployment

Who This Kit Is For
B.Tech Agri Engineering and ECE students working on smart farming projects, researchers at agricultural universities testing precision irrigation, Smart India Hackathon teams prototyping rural IoT, and commercial nursery operators wanting a low-cost soil monitoring solution. If you've outgrown single-sensor Arduino kits and need a field-deployable LoRa network, this kit gives you the complete blueprint.
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?
Scan the QR code in the box to access the Compoden AI companion, trained on this exact project and able to walk you through assembly, wiring, and code. If you need a human, message us on WhatsApp and we'll help you debug.
Can I scale this to more than eight sensor nodes?
The LoRa gateway can handle many nodes, but the included code and power components are optimised for eight. With minor modifications, you can add more Arduinos and sensors; the AI companion includes guidance on scaling.
Does the kit include a GPS module for each node?
The Arduino Nano nodes rely on the gateway's GPS data (collected by the ESP32) to map positions; you can manually assign coordinates in the dashboard. The water-resistant enclosures protect the sensors in the field.
What internet connection does the dashboard require?
The ESP32 gateway connects to your Wi-Fi and pushes data to a cloud dashboard via MQTT. You can also run the dashboard locally on a Raspberry Pi; the kit's documentation covers both options.
Garden - Eight soil nodes send moisture, temp and GPS to a LoRa gateway. Dashboard maps sensor positions with crop health overlays.
