Build Your Own Garden Microclimate Recorder with Arduino — Log Temperature, Humidity & Light Every 15 Minutes

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

Your garden tells a story through temperature swings, humidity shifts, and changing light levels — and this kit lets you capture it all. Whether you’re monitoring a terrace patch of coriander, a school’s botanical corner, or a small farm plot, you’ll assemble a standalone recorder that logs readings every 15 minutes onto onboard EEPROM. Later, just plug into a computer via USB and download the data as a clean CSV file for analysis, no external storage or cloud needed.

What You'll Build

You’ll wire up a DHT22 sensor, an LDR light sensor, and a real-time clock to an Arduino Uno, then upload code that timestamps and stores climate data directly in the microcontroller’s memory. The finished gadget runs on a 9V battery and sits quietly in your garden shed or against a window, building a detailed log you can retrieve anytime. It’s a self-contained microclimate station that turns raw sensor signals into a genuine scientific record.

What You'll Learn

• Interface digital (DHT22) and analog (LDR) sensors with Arduino
• Use the DS3231 RTC module to add accurate timestamps
• Write data to EEPROM and manage memory constraints
• Download logged data over serial and convert to CSV

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Young makers and students will feel right at home. CBSE Class 8–12 learners tackling environmental monitoring assignments, ATL Tinkering Lab explorers, and even B.Tech ECE first‑years tinkering with data logging will find this project engaging. With a little adult help, even a 10‑year‑old can build a real scientific instrument, turning a simple garden into a living lab.

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.
