Digital Twin Real-Time Process Mirror Pro Pro
Build a Real-Time Digital Twin Process Mirror with Arduino Portenta X8
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You’re not just wiring sensors — you’re building a dual-core digital twin system. The Linux‑capable X8 reads DHT22 and ACS712 values every 500ms and pushes them to an AWS IoT Device Shadow; the M4 core simultaneously listens for shadow‑desired states and drives relays exactly as instructed. This is the backbone of predictive maintenance and smart factory applications, ready to prototype on your bench.
What You'll Build
A DIN‑rail‑mounted process mirror that captures temperature, humidity, current, and power from two separate zones, timestamps every reading with the DS3231 RTC, logs to microSD, and displays live status on a 0.96‑inch OLED. Four 24V relays actuate pumps, heaters, or alarms exactly when the cloud shadow commands, all synchronized within half a second. One assembled unit can serve as a standalone endpoint or the first node in a larger Industry 4.0 network.
What You'll Learn
- Co‑process Linux and M4 cores on the Arduino Portenta X8 for deterministic real‑time control
- Provision AWS IoT Core, create and subscribe to Device Shadows, and handle delta updates
- Calibrate ACS712 5A current sensors and integrate industrial‑grade signal conditioning
- Design a production‑ready PCB prototype and mount it in a DIN‑rail enclosure

Who This Kit Is For
This kit is built for practising engineers and advanced makers stepping into Industry 4.0. It fits capstone projects of B.Tech ECE/EEE students, Smart India Hackathon teams prototyping digital twin solutions, and faculty running IoT labs at IITs, NITs, VIT, or BITS. If you already work with embedded Linux or want a hardened reference design for factory‑floor monitoring, you’ll find everything you need here.
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 walks you through every wiring and software step. If you still hit a wall, send a photo over WhatsApp and our build team will debug alongside you.
How do I set up AWS IoT Core for this project?
The companion includes a dedicated module: create a Thing, attach the certificate, define the shadow model, and paste the endpoint into the X8’s Yocto image. You’ll need a free‑tier AWS account.
Can I connect more than four relays or additional sensors?
Yes. The Portenta Max Carrier exposes extra GPIOs, I²C, and CAN. The AI guide shows you how to daisy‑chain another relay board or add Modbus RTU devices via RS‑485.
Is the soldering iron and wire included suitable for this project?
The included 30W iron and lead‑free solder are matched to the prototyping boards. For the DIN‑rail enclosure’s heavier terminals, the companion suggests pre‑heating the pads briefly — a technique covered in the build video.
X8 Linux syncs sensor state to AWS IoT Device Shadow every 500ms. M4 handles hardware actuation from shadow desired state.
