Blockchain-Ready Lawn Irrigation System with Portenta C33 Kit
Build a Blockchain-Anchored Lawn Irrigation Controller 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.
Create a solar-powered, autonomous irrigation system that not only waters your lawn precisely but also posts hardware-signed soil and weather data to a blockchain-anchored agricultural data marketplace via MQTT TLS. You'll learn to leverage the Arduino Portenta C33's secure element for cryptographic signing and build a production-grade IoT device for smart farming.
What You'll Build
You'll assemble a fully functional, weather-resistant irrigation controller with three soil moisture sensors, a light sensor, and a temperature-humidity sensor. The system makes autonomous watering decisions and transmits tamper-proof sensor readings to a decentralized marketplace where data buyers pay for verified agricultural data.
What You'll Learn
- Implement MQTT with TLS for secure data transport to a blockchain-anchored endpoint
- Use the Portenta C33's crypto-chip to sign sensor data directly on hardware
- Integrate solar power management with lithium-ion battery backup for field reliability
- Design a modular outdoor PCB enclosure rugged enough for real-world deployment

Who This Kit Is For
This kit is built for B.Tech final-year ECE and EEE students working on blockchain-IoT projects, Smart India Hackathon teams tackling agriculture data challenges, and researchers at IITs, NITs, and VIT exploring crypto-anchored sensor networks. It assumes familiarity with C/C++ and basic IoT concepts.
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?
Open the AI companion from the QR code on your box. It gives step-by-step help specific to this kit. You can also send a WhatsApp message for human backup.
How does the hardware signing work for the data marketplace?
The Portenta C33's NXP SE050 secure element stores a private key. Before each MQTT publish, the firmware uses that key to sign the sensor payload, so the marketplace can verify data came from your trusted device.
Can I point the system to a different blockchain or MQTT broker?
Yes. The project code is modular; change the broker URI and topic structure, then deploy a corresponding smart contract on Ethereum, Polygon, or any EVM chain. The AI companion includes a reference contract template.
Is the kit ready for outdoor deployment?
Absolutely. The waterproof enclosure, solar panel, and battery management system are designed for continuous lawn operation. Just seal the cable glands properly and the unit withstands rain and dust.
