Hydroponics Nutrient Monitor Kit v7
Hydroponics Nutrient Monitor Kit – Solar-Powered Pi Pico Sensor Logger with GPS
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Hydroponic farmers and agri-tech students constantly need to track environmental conditions across their setups. This kit lets you build a solar-powered, GPS-tagged data logger that records temperature, humidity, and soil moisture every 5 minutes directly onto a microSD card — all sealed inside a waterproof field enclosure. It’s a complete, real-world instrumentation project you can deploy in any outdoor hydroponic bed, greenhouse, or tinkering lab.
What You'll Build
You’ll assemble a rugged, self-contained logging station powered by a Raspberry Pi Pico and solar-charged 18650 batteries. The DHT22 sensor captures air temperature and humidity, the soil moisture sensor tracks root-zone water content, and the NEO-6M GPS adds precise location stamps to every reading. Data timestamps from the DS3231 RTC are written to a microSD card at regular 5‑minute intervals. Everything fits inside the supplied waterproof enclosure, ready for outdoor deployment.
What You'll Learn
- Interface digital sensors (DHT22, soil moisture) with the Pi Pico using MicroPython
- Acquire GPS coordinates and synchronize time with a DS3231 RTC
- Manage solar charging and battery power for an autonomous field device
- Log structured sensor data to a microSD card and retrieve it for analysis

Who This Kit Is For
This intermediate kit fits B.Tech ECE/EEE students building capstone projects, Smart India Hackathon participants prototyping precision agriculture solutions, and CBSE Class 11–12 students exploring applied IoT. ATL Tinkering Labs and IIT/NIT/VIT/BITS teams will find the real-world data logging and solar integration perfect for field trials.
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 for the AI companion that walks you through wiring and code, or drop us a message on WhatsApp for hands-on help.
Can this kit survive outdoor conditions?
Yes, the waterproof enclosure protects the electronics during rain or irrigation spray. Position the solar panel outside and seal cable glands tightly after assembly.
How long does the solar panel keep the Pi Pico running?
With 2× 18650 cells and a 6V 2W panel, the logger runs indefinitely in typical Indian sunlight; battery buffering ensures operation through cloudy periods and nighttime.
Can I view the logged data on my computer?
Absolutely, the microSD card stores data as a CSV file. Simply insert the card into your laptop or phone and open it in any spreadsheet tool to plot trends and map GPS points.
