Smart Garden Watering Kit v12 — Raspberry Pi Growth Tracker with Auto-Irrigation

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

This kit transforms a regular garden bed into a data-driven growing station. The Raspberry Pi 5 captures a daily image with the Pi Camera Module 3 and uses simple computer vision to measure leaf expansion, while soil moisture sensors and a DHT22 trigger a 5V relay to water the plants or switch on a grow light — hands-free and on schedule. It is not just a timer-based watering stick; it builds visual proof of growth over days and lets you log every millimetre of progress.

What You'll Build

A self-contained unit that mounts near your plants, connects to two soil probes and a DHT22, and runs a Python script to compare daily images. When moisture drops below a set threshold, the relay module activates a small water pump or solenoid valve (not included, but any standard 5V pump works). A second relay channel can drive a grow lamp based on temperature readings. All time-stamped images are stored on the 128GB NVMe SSD through the Pi 5 M.2 HAT, giving you a full growth timeline you can scroll through like a botanical time-lapse.

What You'll Learn

• Setting up a Raspberry Pi 5 with an NVMe SSD boot drive and M.2 HAT
• Capturing and storing images using the Pi Camera Module 3 with consistent framing
• Writing a basic OpenCV script in Python to detect green area changes day-to-day
• Reading soil moisture sensors and a DHT22, then triggering relays for irrigation and lighting

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This intermediate kit fits well into CBSE Class 11-12 computer science projects, B.Tech ECE and CSE IoT coursework, and Smart India Hackathon prototypes where sensor data meets image processing. ATL Tinkering Labs can deploy it as a living lab for climate-smart agriculture. Students from NIT, VIT, BITS, and similar institutions working on final-year Edge AI or agri-tech demos will find the camera‑to‑relay pipeline a ready starting point.

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.
