Greenhouse Soil Manager Kit v2
Greenhouse Soil Manager Kit v2 — A LoRa-Powered Soil Sensing Network with GPS-Crop Health Dashboard
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform how you monitor greenhouse soil — deploy eight solar-powered sensor nodes that transmit real-time moisture, temperature, and GPS coordinates to a central LoRa gateway. A custom dashboard then overlays the data on an interactive map, colour-coding zones by crop health. This kit puts precision agriculture control directly into your hands, avoiding the cost and rigidity of proprietary commercial systems.
What You'll Build
You will assemble and deploy a fully wireless soil monitoring network consisting of node stations (each with a capacitive moisture sensor, DS18B20 temperature probe, Arduino Nano, RA-02 LoRa module, and solar charging circuit) and an ESP32-based gateway. The gateway forwards all sensor readings to a dashboard that plots each node's GPS position and displays green/amber/red overlays based on moisture thresholds you define. After 12–15 hours, you will have a working system that can log data continuously and send alerts if a zone dries out.
What You'll Learn
- Calibrate capacitive soil moisture sensors and convert raw ADC values to volumetric water content curves specific to your soil type
- Configure a multi-node LoRa mesh using RA-02 modules and ESP32 gateways, with dynamic addressing and low-power sleep cycles
- Parse NMEA GPS sentences from serial data on Arduino Nano to stamp each sensor reading with latitude and longitude
- Build a web dashboard with Google Maps API overlays, colour gradients, and threshold-driven alerts — all reading from a central MQTT broker

Who This Kit Is For
Built for agritech professionals and serious makers, this kit suits B.Tech final-year ECE/EEE students prototyping smart farming IoT projects for Smart India Hackathon or college majors. It also fits researchers at IITs, NITs, or VIT developing low-cost greenhouse automation, and progressive farmers seeking to digitise soil monitoring without recurring licence fees. If you have soldering experience and basic Arduino IDE familiarity, the advanced build will stretch your skills without overwhelming you.
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 AI companion through the QR code; it remembers every nuance of the Greenhouse Soil Manager circuitry and code. If you still need a human, our support team replies on WhatsApp within hours.
Can I add more than eight sensor nodes later?
Absolutely. The LoRa mesh addressing scheme in the provided firmware can scale to dozens of nodes by adjusting a single constant. Additional solar panels and sensors must be purchased separately.
Does the dashboard require an internet connection once running?
Initially yes, to load Google Maps tiles and set up the broker. After first load, the dashboard can run offline with cached maps if your server and MQTT broker are on the local network.
What type of greenhouse crops will benefit most?
The moisture-overlay logic is crop-agnostic, but the default threshold curves are tuned for high-value greenhouse vegetables like tomatoes, capsicum, and cucumber. You can easily adjust thresholds in the dashboard settings for leafy greens or flowers.
Greenhouse — Eight soil nodes send moisture, temp and GPS to a LoRa gateway. Dashboard maps sensor positions with crop health overlays.
