Hydroponics Nutrient Monitor Kit with Arduino Uno + DHT22
Hydroponics Nutrient Monitor Kit with Arduino Uno – Automate Vent, Pump & Fan for Precision Farming
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a hydroponics setup that self‑regulates — when the temperature rises, a vent opens; when humidity drops, a fan kicks in; when soil moisture is low, a pump waters the roots. With this advanced kit, you build a fully automated nutrient monitor that keeps plants thriving without constant manual intervention, and logs every environmental parameter to an SD card for analysis.
What You'll Build
You’ll construct a functional control unit around an Arduino Uno. The system reads temperature and humidity via DHT22, barometric pressure via BMP280, and soil moisture from two separate probes. Based on real‑time data, it activates servo motors to open a vent, triggers a relay for a fan, and switches a relay pump to maintain targeted nutrient conditions. All readings are timestamped with the DS3231 RTC and saved to a MicroSD card, so you can review plant health trends later.
What You'll Learn
- Interface DHT22, BMP280, and soil moisture sensors to monitor temperature, humidity, pressure, and water content
- Program servo motors to precisely control a physical vent mechanism
- Use relays to safely switch high‑current devices like water pumps and exhaust fans
- Implement time‑stamped data logging with an SD card module and real‑time clock

Who This Kit Is For
This kit is designed for B.Tech ECE/EEE students working on precision agriculture projects, Smart India Hackathon participants building IoT‑based farming solutions, and final‑year engineering students devising automated hydroponics systems. It’s equally useful for ATL Tinkering Labs mentoring advanced maker skills and for hobbyists serious about soilless cultivation.
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?
The AI build companion offers step‑by‑step debugging, and you can reach our support team via WhatsApp for real‑time help.
Can I integrate this kit with an IoT dashboard for remote monitoring?
Yes, the Arduino Uno can be connected to a Wi‑Fi module (not included) to push sensor data to platforms like ThingSpeak or Blynk.
How do I power the pump and fan?
The relay modules can switch external 12V or 230V devices. You’ll need a suitable power source for your pump and fan; the kit provides the control logic.
Is the SD card included?
No, you need to provide your own MicroSD card (up to 32GB recommended). The module writes CSV files for easy analysis in Excel or Python.
