Hydroponics Data Logger Kit with Arduino Mega
Log Hydroponic Conditions for Scientific Analysis with the Arduino Mega Data Logger Kit
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 puts a complete hydroponics monitoring station in your hands. With two DHT22 sensors measuring temperature and humidity at different points, a BMP280 tracking atmospheric pressure, a BH1750 capturing light intensity, and soil moisture probes in the nutrient solution, you will generate timestamped CSV files on a microSD card - ready for graphing in Excel or Google Sheets. Ideal for biology-engineering crossover experiments, this build gives you hard data to analyse how micro-environments shift over hours or days.
What You'll Build
You will assemble a bench-top sensor array that reads all environmental parameters every few seconds, displays live values on a crisp OLED screen, and writes every reading to a microSD card with an exact timestamp from the DS3231 real-time clock. The result is a rugged, deployable logger that can sit inside a grow tent, greenhouse corner, or classroom hydroponics rig for days - then deliver a complete dataset for post-experiment analysis without a laptop being connected.
What You'll Learn
- Interfacing multiple I2C sensors (BMP280, BH1750, OLED) and digital sensors (DHT22) with an Arduino Mega simultaneously
- Logging time-stamped data to a microSD card using the DS3231 RTC for precise interval recording
- Reading analog soil moisture sensors and converting voltage to meaningful moisture percentage
- Displaying real-time multi-channel data on a 0.96-inch OLED to monitor system health at a glance

Who This Kit Is For
This intermediate kit speaks directly to CBSE Class 11-12 students turning a biology project into a data-rich investigation, B.Tech ECE/EEE undergraduates building an environmental monitoring mini-project, and ATL Tinkering Lab participants prototyping a Smart India Hackathon entry. It expects some prior Arduino familiarity - you should be comfortable uploading a sketch and reading serial output - but every wiring step and code block is explained.
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 inside the box to chat with the AI companion trained on this specific kit; if you prefer a human touch, WhatsApp us and we'll help you debug in real time.
Is this kit suitable for a biology project on plant growth?
Yes. The sensor array lets you log temperature, humidity, light, and root-zone moisture simultaneously - exactly the variables needed to analyse how environment affects germination or growth rate in a hydroponic system.
Can I view sensor readings live on the display?
The OLED cycles through temperature, humidity, pressure, light, and soil moisture every few seconds, so you can monitor conditions instantly while the data also writes quietly to the SD card.
What extra items are needed to get started?
A standard USB Type-B cable (often used with printers) is required to connect the Mega to your computer - this is not included. Any 9V battery powers the logger for standalone deployment; you may also use a USB power bank.
