Industrial SCADA HMI Panel Kit with Arduino Mega + DHT22
Build a Professional SCADA HMI Panel with Arduino Mega, DHT22 & 2.4-inch TFT Touch
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Take the leap from basic Arduino projects to a fully functional industrial control panel. This kit lets you build a touchscreen-operated SCADA HMI that displays live data from 8 sensor channels—temperature, humidity, current, pressure, and more—while controlling relays directly from the screen. Perfect for final-year engineering projects, industrial automation enthusiasts, or anyone preparing for Smart India Hackathon challenges that demand real-world sensing and control interfaces.
What You'll Build
You’ll assemble and program a DIN-rail mountable panel that reads multiple sensors—DHT22, BMP280, dual ACS712 current sensors—and visualizes them as analog-style gauges on a 2.4-inch TFT display. Touch buttons let you switch relays ON/OFF, while a DS3231 RTC timestamps data logged to a microSD card. The final unit mimics a professional SCADA terminal, ready to demonstrate on your college demo day.
What You'll Learn
- Multiplexing sensor data from six different protocols (I2C, analog, digital) on Arduino Mega.
- Designing responsive touchscreen user interfaces using the ILI9341 TFT library.
- Implementing deterministic relay control logic with hardware interrupts and RTC schedules.
- Building noise-immune sensor circuitry with proper decoupling capacitors and PCB prototyping.

Who This Kit Is For
Designed for B.Tech ECE/EEE students building capstone or minor projects, Smart India Hackathon participants, and engineering aspirants at IIT, NIT, VIT, or BITS Pilani who need a demonstration-ready industrial prototype. If you’ve mastered blinking LEDs and want to show a panel that communicates via Modbus-like protocols and logs data, this kit accelerates your path from concept to working hardware.
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?
Just scan the QR code to chat with the AI companion, or drop a WhatsApp message to our support team. You’ll get step‑by‑step unblocking tailored to this kit’s wiring and code.
Can I modify the UI to display more gauges or different sensor types?
Absolutely. The AI companion includes guidance on customizing gauge layouts and adding new sensor drivers. The Arduino Mega’s abundant GPIO and memory give you headroom for up to 12 sensor channels.
Does this kit require industrial voltage inputs, or is it safe for a lab desk?
All sensors operate on 5V/12V DC within the provided power supply. The ACS712 modules measure current non-invasively via terminal blocks. No direct connection to mains AC is needed—perfect for a university lab environment.
How do I mount this into a final enclosure for my project showcase?
The included DIN Rail Enclosure snaps onto standard DIN rails. We provide a drilling template and mounting standoffs. The AI companion also suggests 3D‑printable front panels if you need a custom look.
Mega with TFT touch shows 8 sensor gauges. Relay control from touch buttons on screen.
