Greenhouse Soil Manager Kit: Compare Soil & Hydroponics with Arduino

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

Build a sensor station that simultaneously tracks soil moisture, temperature, and light intensity in both traditional soil and a hydroponic grow tray. The dual-sensor design lets you quantify which growing method maintains steadier conditions for herbs, leafy greens, or classroom botany experiments. All readings are timestamped and stored on a microSD card, then displayed on the OLED screen in real time.

What You'll Build

A benchtop greenhouse data logger that monitors two growing environments side by side. You’ll wire two DS18B20 temperature probes, two analog soil moisture sensors, and a BH1750 lux sensor to an Arduino Mega. The system logs temperature, humidity, and light readings with an RTC-stamped timestamp, then shows a rolling comparison on the OLED. It’s designed to sit on a windowsill or under a grow light, giving you hard data on which method — soil or hydroponic — offers more plant-friendly conditions throughout the day.

What You'll Learn

• Calibrate and compare sensor readings across two parallel systems
• Manage I2C communication between BH1750, OLED, and RTC on a single Arduino Mega
• Implement data logging to microSD with buffered writes to minimize card wear
• Analyze and visualize environmental data to evaluate plant-growing strategies
