Hydroponics Nutrient Monitor Kit v3
Hydroponics Nutrient Monitor Kit v3 – Arduino Portenta C33 with Blockchain-Signed IoT for 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.
Turn your hydroponics setup into a verifiable data stream. This kit uses the Arduino Portenta C33’s hardware secure element to cryptographically sign soil moisture, humidity, temperature, and light readings, then pushes them to a blockchain-anchored agricultural data marketplace over MQTT TLS. Whether you are an agritech researcher or a blockchain developer, you’ll create a tamper-proof field unit that proves every sensor reading is authentic.
What You'll Build
A solar-powered, waterproof field monitor that fuses data from multiple sensors, timestamps each reading with an RTC, signs it onboard, logs locally to SD, and publishes an immutable data stream. Use it to record hydroponic conditions that no one can dispute – ideal for data marketplaces, crop insurance claims, or precision agriculture research.
What You'll Learn
- Implementing hardware-based cryptographic signing on the Arduino Portenta C33 using its secure element
- Publishing authenticated MQTT messages with TLS encryption for IoT data integrity
- Designing a solar-powered data logger with low-power management for outdoor deployment
- Building a complete sensor fusion system combining soil moisture, DHT22, and BH1750 for precision agriculture

Who This Kit Is For
This advanced kit is built for B.Tech ECE/EEE students working on IoT & blockchain capstone projects, Smart India Hackathon teams tackling agritech challenges, and researchers at IITs, NITs, VIT, or BITS exploring trusted data flows in hydroponics. If you’ve worked with Arduino and MQTT before, and want to add hardware-backed security to your sensor networks, this is your next step.
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 knows every connection in this kit. You can also WhatsApp us directly for hands-on guidance.
Do I need prior blockchain experience to complete this kit?
No. The provided code abstracts blockchain interactions. The AI companion walks you through each line, and you’ll learn signing and TLS messaging from scratch.
Can I test the data marketplace integration without paying any fees?
Yes, the kit connects to a permissioned test network for learning. If you later move to a production marketplace, we provide migration resources.
How reliable is the solar power system for continuous outdoor use?
With the 6V 2W panel, two 18650 cells, and low-power management, the system runs 24/7 even during overcast days typical of Indian monsoon seasons.
Hydroponics — C33 with hardware-signed sensor readings posts to a blockchain-anchored agricultural data marketplace via MQTT TLS.
