Greenhouse Soil Manager Advanced Kit with Arduino Uno + Sensor
Greenhouse Soil Manager Advanced Kit — Arduino Uno + 3 Probes Proxy NPK, OLED Tells You When to Fertilize
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 greenhouse system that reads your soil's needs and tells you exactly when to fertilize. This kit uses three strategically placed soil moisture sensors and a temperature probe to proxy key nutrient levels—no expensive NPK sensor required. Build it, calibrate it, and get a working soil manager that's a stepping stone into agri-tech and IoT.
What You'll Build
A portable soil monitoring station that reads moisture and temperature from multiple spots, correlates readings to estimate NPK levels, and displays a clear fertilizer recommendation on an OLED screen. Perfect for school science exhibitions, hackathons, or a first step into precision farming.
What You'll Learn
- Calibrating soil moisture sensors for conductivity-based NPK estimation
- Reading and processing analog sensor data with Arduino
- Displaying real-time sensor values and recommendations on an OLED
- Understanding the relationship between soil moisture, temperature, and nutrient availability

Who This Kit Is For
Designed for CBSE Class 11-12 students exploring agri-tech projects, B.Tech ECE/EEE undergraduates building prototypes for Smart India Hackathon, and hobbyists wanting to understand precision farming. Perfect for school science exhibitions and college mini-projects in IoT and sensor networks.
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 on the box to start chatting with the AI companion trained on this kit. If you need human help, drop us a WhatsApp message—we respond within hours.
How accurate is the NPK proxy using just moisture sensors?
This kit estimates NPK based on conductivity correlations, not direct measurement. It's a fantastic learning tool to understand sensor fusion and approximations used in low-cost agricultural sensors. For real precision farming, it demonstrates the concept.
Can I power it with a solar panel instead of a 9V battery?
Absolutely. You can connect a 5V solar power module to the Arduino’s Vin pin, just like many greenhouse setups. The AI companion can guide you through the wiring changes.
Does this kit include code for the OLED display?
Yes, the AI companion provides ready-to-upload code tuned for this exact sensor combination. You'll have the OLED showing moisture percentages and a fertilizer recommendation within minutes of finishing wiring.
