Drip Irrigation Solar Powered Variant 15 Kit with Arduino Nano + Sensor
Build a Solar-Powered Automatic Drip Irrigation System with Arduino Nano
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 drip irrigation system that never over‑waters, never wastes battery, and never needs a wall outlet. You’ll build exactly that: a solar‑charged, Arduino Nano‑powered controller that reads soil moisture in two zones, triggers a submersible pump only when the earth is dry, and then sinks into deep sleep to conserve energy. Perfect for school agri‑tech projects, college hackathons, or your own terrace garden.
What You'll Build
A self‑sustaining irrigation controller that harnesses a 6V solar panel to charge dual 18650 Li‑ion cells. Two soil moisture sensors independently monitor zones; when either drops below a threshold, the Arduino wakes, activates a relay, and runs the mini pump for a calibrated burst. Between readings the whole system enters power‑down sleep, stretching battery life for cloudy days. The finished board fits on a breadboard, ready to be housed in a weatherproof box for real‑world use.
What You'll Learn
- Solar charging and Li‑ion battery management with TP4056 and protection diodes
- Interfacing and calibrating resistive soil moisture sensors for reliable thresholds
- Arduino low‑power sleep modes and wake‑up‑on‑sensor logic
- Driving a 5V relay and pump safely from battery power

Who This Kit Is For
CBSE Class 11–12 students building a physics or computer science investigatory project, B.Tech ECE/EEE undergraduates preparing for Smart India Hackathon or final‑year agri‑tech prototypes, and ATL Tinkering Lab mentors introducing embedded systems. If you need a field‑ready, solar‑driven automation concept that demonstrates power optimisation and sensor integration, this kit delivers a 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 inside the box — the AI companion gives step‑by‑step help, and you can also message us on WhatsApp for human support.
How long does the battery last without sun?
The deep‑sleep logic draws microamps between soil checks. Even with two 18650 cells, you’ll get 3–5 days of autonomous watering without recharging.
Can I add more soil sensors later?
Yes, the Arduino Nano has spare analogue pins. The AI companion explains how to extend the code for additional zones.
Is the pump strong enough for a drip line?
The included mini submersible pump feeds 2–4 drippers easily. For a larger network you’d need a higher‑flow pump and a separate power supply — the relay can still switch it.
Solar charged battery powers soil moisture triggered relay pump. Deep sleep between checks.
