ESP32 OPC-UA Industrial Server Kit with ESP32 + DHT22
ESP32 Industrial OPC-UA Sensor Server Kit with DHT22, ACS712 & BMP280
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn an ESP32 into an OPC-UA server that industrial SCADA platforms can discover and poll. This kit equips you with two DHT22 temperature-humidity sensors, an ACS712 current sensor, and a BMP280 pressure sensor—each mapped as a distinct, addressable node inside the OPC-UA information model. You'll build a DIN-rail-mountable embedded server, then monitor live sensor data from Ignition, openSCADA, or any standard OPC-UA client.
What You'll Build
You'll assemble a self-contained, industrial-grade sensor server that publishes real-time temperature, humidity, current, and atmospheric pressure as tagged OPC-UA variables. By the end of the 5–6 hour build, your ESP32 will serve up sensor nodes over Ethernet/Wi‑Fi, and you'll understand how to namespace objects, handle client subscriptions, and set secure endpoints. The finished unit fits inside a DIN rail enclosure—ready for an automation panel or a Smart India Hackathon demo table.
What You'll Learn
- Implement an OPC-UA server on an ESP32 using the open62541 stack
- Map physical sensors (DHT22, ACS712, BMP280) to OPC-UA nodes with correct data types and units
- Interface industrial SCADA software (Ignition, openSCADA) with embedded hardware
- Prototype a multi-sensor array on a PCB and package it in a DIN rail enclosure for realistic deployment

Who This Kit Is For
This kit is built for students taking their first serious step into industrial IoT—CBSE Class 11–12 with AI/ML or electronics electives, first-year B.Tech ECE/EEE learners, and participants in Smart India Hackathon or ATL Tinkering Lab challenges. It also delivers a strong foundation project for IIT, NIT, VIT, or BITS students prototyping OPC-UA–based automation solutions right in the hostel lab.
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, reached through the QR code on the box, can walk you through wiring, code upload, and OPC-UA endpoint configuration; if you need human help, our WhatsApp support is available within business hours.
Can I connect this to commercial SCADA software like Ignition or WinCC?
Yes. The OPC-UA server follows the standard, so you can discover and connect it from Ignition, openSCADA, Proficy, or any OPC-UA client after setting the correct endpoint URL in the client configuration.
Do I need prior experience with OPC-UA or industrial protocols?
No. The included guide and AI companion explain namespace creation, node IDs, and subscription handling from scratch. If you are comfortable with the Arduino IDE and basic sensor wiring, you can complete the build successfully.
How can I add more sensors later?
The ESP32 firmware template is designed for expansion. You can declare new OPC-UA variables for additional sensors, wire them on the prototyping board, and the AI companion can help you adapt the code for devices like DS18B20 or volatile organic compound sensors.
ESP32 implements OPC-UA server exposing sensor nodes as addressable objects for industrial SCADA.
