Lawn Irrigation Controller Kit v8
Lawn Irrigation Controller Kit v8 — Raspberry Pi Pico Automated Plant Waterer
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 a dry patch of lawn or a potted plant into a self-watering oasis. This kit uses a soil probe that constantly reads moisture levels; when the ground gets too dry, a Raspberry Pi Pico triggers a peristaltic pump for exactly 5 seconds, delivering a precise water dose through a silicone tube. The result is a compact, reliable automatic plant waterer that works while you’re away, no babysitting needed.
What You'll Build
You’ll assemble a complete automatic plant watering system. A soil moisture sensor buried in the soil sends real-time data to the Pico. When moisture drops below a threshold you set (or the pre-loaded value), the L298N driver spins the peristaltic pump for a short pulse—watering just enough, never too much. The circuitry and code are minimal and clear, giving you a fully functional miniature irrigation controller you can install in a garden or classroom project.
What You'll Learn
- Reading analog sensor data from a soil moisture sensor and interpreting voltage thresholds.
- Controlling a DC pump with an L298N motor driver and understanding back-EMF protection using diodes.
- Writing and modifying MicroPython code on Raspberry Pi Pico to implement if-this-then-that automation.
- Soldering components onto a prototype board and assembling a working circuit from scratch.

Who This Kit Is For
Designed for young makers in ATL Tinkering Labs, school science exhibitions, and curious children from Class 5 upward. No prior electronics or coding experience is needed—the AI guide walks you through every connection and line of code. Parents and educators will appreciate how this single kit combines soldering practice, sensor logic, and real-world automation into a project that actually waters plants.
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 chat with the AI companion trained on this exact project. You can also reach us on WhatsApp for human help, any time during your build.
Do I need programming experience?
Not at all. The kit includes a pre-written MicroPython script that you upload to the Pico. The AI companion explains each line so you can tinker and learn coding step by step.
Can I adjust the watering duration?
Yes. The code is open and easy to modify. You can change the pump run time from 5 seconds to any interval, and even tweak the soil moisture threshold to suit different plants.
Does this kit work for multiple plants?
This controller is built around one soil sensor and one pump. For multiple plants, you can extend the circuit with additional sensors or use multiple kits; the AI guide can show you how to expand.
