Digital Twin Real-Time Process Mirror
Digital Twin Real-Time Process Mirror Kit — Arduino Portenta X8 & AWS IoT
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 lets you build an industrial-grade digital twin that reads dual DHT22 temperature/humidity sensors and ACS712 current sensors, syncs their states to AWS IoT Device Shadow every 500ms via the Portenta X8’s Linux core, and the M4 microcontroller core actuates a relay based on shadow desired state—a complete process mirror. It mirrors a real two-channel environmental and power monitoring system, ideal for prototype factories, remote labs, or IIoT gateways.
What You'll Build
A fully functional digital twin of a two-channel environmental monitoring and power control system. On the Portenta X8’s Linux side, Python scripts continuously read temperature, humidity, and current data, pushing to AWS IoT Core. The M4 core subscribes to shadow updates and drives the relay to toggle loads—mirroring desired states in real-time. The 0.96-inch OLED displays local status, while an RTC and MicroSD capture time-stamped logs for later analysis.
What You'll Learn
- Dual-core processor architecture: Offloading sensor ingestion to Linux while using M4 for real-time actuation, with inter-core communication.
- AWS IoT Device Shadow protocol and MQTT with tight 500ms sync intervals, state versioning, and delta handling.
- Interfacing analog sensors (DHT22, ACS712) and SPI/I2C peripherals (OLED, RTC, SD) in a noise-hardened industrial context with DIN rail enclosure.
- Power management with LM2596 buck converter and firmware-controlled relay sequencing from cloud shadow desired states.

Who This Kit Is For
B.Tech ECE/EEE final-year students building Industry 4.0 capstone projects, Smart India Hackathon participants prototyping IIoT digital twins, and professionals creating edge gateways for AWS IoT. Also ideal for corporate R&D labs in Bengaluru and Pune, and M.Tech researchers at IITs, NITs, and BITS Pilani exploring dual-core real-time systems.
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 to access the AI companion trained on this kit; if you need human help, WhatsApp our support team for live guidance.
Do I need an AWS account to run this project?
Yes, you'll need an AWS account with IoT Core permissions. Our guide includes step-by-step instructions to create a Thing, attach policies, and set up certificates.
Can I monitor the digital twin remotely?
Absolutely — the MQTT shadow updates every 500ms to AWS, viewable from any web dashboard or the AWS IoT MQTT test client.
Is this kit suitable for a college final-year project?
Definitely. The dual-core Linux-M4 architecture and AWS integration align with B.Tech ECE/EEE capstone requirements and provide a strong basis for research papers.
X8 Linux syncs sensor state to AWS IoT Device Shadow every 500ms. M4 handles hardware actuation from shadow desired state.
