Lawn Irrigation Controller Kit v4
Lawn Irrigation Controller Kit v4 – Build a Blockchain-Verified Sensor Network 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 transforms a standard lawn irrigation setup into a cryptographically-secured data node. Using the Arduino Portenta C33’s on‑board secure element, sensor readings are hardware‑signed and pushed via MQTT TLS to a blockchain‑anchored agricultural data marketplace – creating immutable, verifiable environmental records that can be monetized or used for precision agriculture research.
What You'll Build
A fully functional lawn irrigation controller that monitors soil moisture, humidity, light, and temperature across up to three zones. Data is automatically timestamped, signed at the hardware level by the Portenta C33, and published over an encrypted MQTT channel to a blockchain‑restricted marketplace. The system runs entirely on solar power, logging a backup copy of all readings on a microSD card inside a weatherproof enclosure.
What You'll Learn
- Implementing hardware‑based trust using the Portenta C33’s secure element for signing sensor payloads
- Configuring TLS‑secured MQTT communication to a blockchain‑anchored message broker
- Integrating multiple sensors (soil moisture, DHT22, BH1750) with an RTC and local storage on SD card
- Designing a solar‑powered remote monitoring system with battery charge management

Who This Kit Is For
B.Tech final‑year students in ECE, EEE, or CSE seeking a blockchain‑IoT capstone project; researchers at IITs, NITs, VIT, or BITS Pilani working on decentralized agri‑tech; Smart India Hackathon teams building secure sensor networks for agricultural data marketplaces. The hardware‑rooted trust model meets rigorous project requirements and provides a strong foundation for journal publications or patent prototypes.
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?
Your kit includes an AI companion trained specifically on this project, accessible via QR code; you can also connect with our support team on WhatsApp for direct guidance.
Does this kit include a blockchain node, or does it only publish data?
The kit publishes signed data to an existing blockchain marketplace; it does not run a full node. We provide a demo endpoint so you can test the flow instantly and see your data on a testnet ledger.
Can I use this for a college final‑year project or research paper?
Absolutely. The hardware‑rooted trust model and MQTT‑blockchain integration are cutting‑edge topics suitable for B.Tech/M.Tech projects in ECE/EEE/CSE. Many students have successfully published work based on similar Compoden kits.
Is the solar setup enough for continuous operation in the field?
The 6W solar panel with two 18650 cells and buck converter provides sufficient power for periodic sensor readings and MQTT transmissions, typical of agricultural monitoring. In average Indian sunlight, the system can run indefinitely with correct sleep‑wake cycles.
Lawn — C33 with hardware-signed sensor readings posts to a blockchain-anchored agricultural data marketplace via MQTT TLS.
