Hydroponics Nutrient Monitor Kit v10
Hydroponics Nutrient Monitor Kit — Arduino Data Logging for STEM Agriculture
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Grow a miniature hydroponic garden and watch how moisture and temperature change day by day. This kit turns an Arduino Nano into a logger that records soil moisture from two sensors and ambient temperature onto a MicroSD card. Use the included seed trays to start your own STEM agriculture experiment — no prior coding needed.
What You'll Build
You'll assemble a monitoring station that reads two soil moisture probes and a waterproof temperature sensor. The Arduino timestamps each reading and writes a CSV file to the SD card. Plug the MicroSD into any computer to open the file and graph how moisture drops as plants consume water, and how temperature fluctuates. You'll have a real dataset to analyze within hours of first power-up.
What You'll Learn
- Wiring analog soil moisture sensors and a digital temperature sensor to Arduino Nano
- Reading analog voltage and converting to moisture percentage
- Using the DS18B20 one-wire protocol for accurate temperature logging
- Writing time-stamped data to a MicroSD card using the SD library

Who This Kit Is For
This kit is designed for CBSE Class 8-10 science projects, ATL Tinkering Labs, and school exhibition teams exploring agriculture technology. B.Tech ECE and EEE students can use it as a quick prototyping tool for smart farming concepts. Even a curious 10-year-old can follow the AI guide and start logging within an afternoon.
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 on the box to open the AI companion, which walks you through wiring and code. You can also post a photo on WhatsApp — our engineers typically reply within 2 hours.
Does the kit include seeds or growing medium?
Seed trays are provided, but seeds and growing medium are not included. You can use any quick-sprouting seeds like mung beans or fenugreek with cotton wool or hydroponic sponge.
How long can the logger run continuously?
The 4GB MicroSD card stores millions of readings — enough for months of minute-by-minute logging. Keep the Arduino powered via USB or a power bank for multi-day experiments.
Can I monitor more than two plants?
The code is set for two sensors. If you want to add a third, the AI companion includes instructions for expanding the setup using the spare breadboard rows.
