Hydroponics Nutrient Monitor Advanced Kit with Arduino Uno + Sensor
Build a Hydroponics Nutrient Monitor & Data Logger with Arduino Uno
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Whether you’re growing leafy greens in a classroom hydroponics setup or optimizing nutrient solutions for a science fair, this kit gives you a professional-grade monitoring tool. You’ll log soil moisture, temperature, and light intensity every hour to an SD card, then chart trends over weeks to understand exactly what your plants need for peak growth. No guesswork, no disconnected parts—just a complete system that turns sensor data into actionable insights.
What You'll Build
A standalone data logger that reads substrate moisture (using a soil moisture sensor), ambient temperature via a waterproof DS18B20 probe, and light level (BH1750 lux sensor), timestamped by a real‑time clock. Live readings appear on a crisp OLED display, while every measurement gets saved to a microSD card as a CSV file. You’ll wire everything on a breadboard, flash the Arduino Uno, and mount the sensor nodes in your hydroponic tray to start tracking the environmental variables that affect nutrient uptake and plant health.
What You'll Learn
- Interface analog and digital sensors—moisture, temperature, light—with Arduino’s I/O and I2C bus
- Write timestamped data to an SD card using SPI and format logs for easy analysis in Excel or Python
- Drive an OLED display and a DS3231 RTC over I2C, managing memory and time synchronisation
- Manage power from a 9V battery, understand sensor calibration, and plot growth‑condition charts over weeks

Who This Kit Is For
This kit is an ideal fit for CBSE Class 11–12 students tackling a physics or biology investigatory project, B.Tech ECE/EEE undergrads prototyping agriculture IoT systems, and participants in the Smart India Hackathon or ATL Tinkering Labs. Even IIT, NIT, VIT, or BITS Pilani engineering students will find it a solid hands‑on introduction to embedded data logging and sensor fusion.
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 from the box to open the AI companion, which walks you through every connection and code step. If you still need help, message us on WhatsApp and we’ll guide you directly.
Can I view the logged data on a computer?
Yes. The microSD card stores a CSV file with timestamps; simply eject the card, insert it into a laptop, and open it with Excel or Google Sheets to create growth‑condition charts.
Does this work for both soil and hydroponic setups?
The included soil moisture sensor is designed for coco coir, perlite, or rockwool substrates. For pure deep‑water culture, you may want to swap it with a waterproof capacitive sensor (not included), and the AI companion explains how to adapt the circuit.
How long can the system log before I need to change the battery?
With a standard 9V alkaline battery, the logger runs for several hours. For multi‑week logging trials, connect a USB power bank (5V) to the Arduino instead—the build guide shows exactly where to plug in.
Hydroponics — Soil moisture + temperature + light logged every hour to SD. Charts growth conditions over weeks.
