Nano Soil Moisture Probe Kit with Arduino Nano + Sensor
Arduino Nano Soil Moisture Probe Kit – Solar Plant Watering Alert
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Stop guessing when your plants need water. The Compoden Nano Soil Moisture Probe Kit lets you build a compact, waterproof sensor rod that lights up red when soil is dry and green when it’s moist — all powered by a solar-charged battery so you never touch a charger again. It’s a complete, frustration-free project for budding electronics enthusiasts and students who want a gadget that actually solves a daily problem.
What You'll Build
A standalone probe you insert into any pot or garden bed. Red and green LEDs instantly tell you whether it’s time to water. The capacitive sensor never corrodes, and the 6V solar panel keeps the 18650 battery topped up indefinitely. You’ll walk away with a zero-maintenance tool that keeps your plants happy and a deep understanding of how Arduino-based sensing works.
What You'll Learn
- How capacitive soil moisture sensing works — far more durable than resistive probes
- Programming an Arduino Nano to read analog values and control LED output
- Building a safe solar charging circuit using a TP4056 module and 18650 cell
- Soldering components onto a prototype board and sealing everything in a waterproof enclosure

Why Buy This Kit Instead of Sourcing Parts Separately
| Factor | Sourcing Separately | Compoden Kit |
|---|---|---|
| Compatibility checks | You verify every part | Pre-tested as a system |
| Build support | Forums and scattered tutorials | AI companion trained on this exact project |
| Time to first working build | Days of debugging | Hours, with step-by-step guidance |
| Shipping coordination | Multiple sellers, multiple delays | One shipment from Bengaluru in 3-5 days |
Who This Kit Is For
Rated for ages 5-15, but adult supervision is recommended for the soldering portion. It’s a hit with CBSE Class 6-12 students preparing science models, ATL Tinkering Lab members, and B.Tech ECE/EEE first-years working on embedded projects. Perfect for a parent–child weekend build or a Smart India Hackathon prototype that demonstrates real-world IoT.
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 to chat with the AI companion specifically trained on this kit. It can walk you through every connection and code step. If you still need help, message us on WhatsApp and a real maker will guide you.
Is this kit safe for young children?
The soldering requires hot tools, so we recommend an adult do that part for builders under 12. Everything else — sensing, wiring, and coding — is hands‑on and safe for ages 5+ with proper supervision.
Does the soil sensor work in all types of soil?
The capacitive sensor performs well in regular potting mix, garden soil, and sandy loam. Very dry, rocky, or pure clay soils can be calibrated by adjusting the threshold code we provide.
Can I use this kit for a school science exhibition?
Absolutely. The built probe, with its LED feedback and solar power, makes a compelling display of IoT and sustainability. The included AI guide even suggests presentation talking points.
