Grow Healthier Plants with Arduino: Log Soil Moisture, Temperature & Light to an SD Card

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

Houseplant owners know the guessing game: is the soil too dry? Did the temperature drop too low last night? This kit replaces guesswork with data. You'll build a monitor that records soil moisture, temperature, and light intensity every hour onto a microSD card. Over days and weeks, you'll see exactly how your care routines impact plant health-giving you the confidence to water and place plants perfectly.

What You'll Build

A compact sensing station that sits beside your favorite houseplant. It reads soil moisture with a probe, ambient temperature with a waterproof DS18B20, and light levels with a BH1750 lux sensor. A DS3231 real-time clock timestamps every reading, and the Arduino stores it as a CSV file on the SD card. The 0.96-inch OLED shows live values, so you can check conditions at a glance without pulling the card.

What You'll Learn

• Integrate multiple I2C and one-wire sensors into a single Arduino sketch
• Log timestamped sensor data to a microSD card in CSV format for analysis
• Use an RTC to maintain accurate time even when the Arduino is powered off
• Display real-time readings on an OLED and understand basic menu logic
