Certified Agricultural IoT Node Pro Pro
Certified Agricultural IoT Node Pro — Build a Blockchain-Verified Data Logger 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.
This kit propels you straight into the agritech frontier: a solar-powered sensor node that cryptographically signs each reading and publishes it to a blockchain-anchored data marketplace. By assembling this node, you gain a deployable asset capable of generating trusted, monetizable agricultural intelligence — exactly what smart farming consortia and climate data networks demand.
What You'll Build
You’ll construct a rugged, waterproof sensor station that tracks soil moisture at three depths, ambient conditions, and light levels. The Arduino Portenta C33 acts as the secure brain, running an MQTT TLS client that pushes tamper-evident payloads to a public blockchain ledger, establishing verifiable data provenance without intermediaries.
What You'll Learn
- Hardware-level sensor signing using the Portenta C33’s secure element to guarantee data integrity
- Configuring MQTT over TLS for encrypted, authenticated data streams to blockchain marketplaces
- Designing an autonomous solar power system with 18650 battery management and buck regulation
- Timestamping and local logging with a DS3231 RTC and MicroSD for robust offline buffering

Who This Kit Is For
This kit is tailored for advanced students and professionals in India—final-year B.Tech ECE/EEE candidates, Smart India Hackathon teams developing agritech prototypes, and researchers at IIT/NIT/VIT/BITS exploring blockchain-anchored IoT. Startups building verifiable data marketplaces for precision farming will find a ready-to-deploy hardware reference, cutting months off development.
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 interactive debugging, and you can escalate to our WhatsApp support for direct guidance from the Compoden team.
Is the blockchain marketplace access included?
This kit provides the hardware and firmware to sign and push data via MQTT TLS. You may connect to any compliant blockchain marketplace; we include example code for a public testnet.
Can I use this kit for academic projects?
Absolutely. The hardware-signed data chain provides a strong rigor component for B.Tech final projects, hackathons, or research publications on agricultural IoT security.
Is the solar panel sufficient for continuous operation?
Yes, when paired with the 18650 cells in typical Indian sunlight, the 2W panel keeps the node running indefinitely with the low-power Portenta C33, provided sensing intervals are not too frequent. Guidance is included.
C33 with hardware-signed sensor readings posts to a blockchain-anchored agricultural data marketplace via MQTT TLS.
