Certified Agricultural IoT Node
Build a Blockchain-Ready Agricultural IoT Node with Arduino Portenta C33
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 soil moisture, humidity, and light data into immutable, tradeable digital assets. This kit enables you to build a portable field node that cryptographically signs every sensor reading at the hardware level, then uploads the authenticated data to a blockchain-anchored marketplace via encrypted MQTT TLS — perfect for precision agriculture and carbon credit verification projects.
What You'll Build
You'll assemble and deploy a rugged, solar-powered IoT device that monitors three soil moisture points, ambient temperature/humidity, and light intensity. The node autonomously timestamps readings with a real-time clock, stores backups on microSD, and transmits secure, verifiable data packets over TLS. The waterproof enclosure protects against field conditions, making it ready for long-term agricultural data trials.
What You'll Learn
- Implement hardware-based digital signing using the Portenta C33’s secure element
- Configure TLS-secured MQTT communication for IoT data transfer
- Interface multiple agricultural sensors and manage power with solar charging and battery management
- Anchor sensor data to a blockchain testnet via a marketplace API to create tamper-proof records

Who This Kit Is For
This kit targets advanced engineering students (B.Tech ECE/EEE final year and postgraduates), agritech startup teams prototyping secure IoT data pipelines, and participants in Smart India Hackathon challenges around blockchain in agriculture. If you need to demonstrate cryptographic proof of data origin for research or commercial agri-data exchanges, this kit provides a complete, validated starting point.
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 companion provides stepwise assembly, wiring diagrams, and code snippets. If you need human help, WhatsApp support connects you directly to our team.
Does this kit include a blockchain network subscription?
The kit includes example code to connect to a public testnet marketplace; no subscription is needed for prototyping and testing.
Can I replace the sensors with others?
The Portenta C33 and carrier board support a wide range of I2C and analog sensors. Our AI companion can assist with adapting code and wiring for your specific sensor choices.
Is soldering required?
Yes, you will solder the sensors, power management modules, and connectors onto the prototype board. A soldering iron and solder wire are included in the kit.
C33 with hardware-signed sensor readings posts to a blockchain-anchored agricultural data marketplace via MQTT TLS.
