ESP32 OPC-UA Temperature Monitor Kit for SCADA Integration
ESP32 OPC-UA Temperature Monitor Kit: Build SCADA-Ready Server Room Monitoring
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform raw sensor data into an industrial-grade SCADA node. This kit guides you through building an ESP32 server that exposes temperature, humidity, pressure, and current readings as OPC-UA objects - ready to integrate with any SCADA system like WinCC or Ignition. Designed for data centre environments, it's your gateway to understanding Industry 4.0.
What You'll Build
You'll assemble a DIN-rail mounted monitoring unit that continuously tracks ambient temperature, humidity, barometric pressure, and current consumption via the ACS712. The ESP32 runs an OPC-UA server, making every sensor value addressable by a SCADA client over your network. Ideal for mock data centre labs and industrial automation projects.
What You'll Learn
- Implementing an OPC-UA server on an ESP32 using the open62541 stack
- Reading digital sensors (DHT22, BMP280) and an analog current sensor (ACS712) and mapping them to OPC-UA nodes
- Soldering components onto a prototype PCB and housing them in a DIN rail enclosure
- Connecting the node to SCADA software like WinCC for real-time data visualisation and trend analysis

Who This Kit Is For
This kit suits B.Tech ECE/EEE students building industrial IoT lab assignments, participants of Smart India Hackathon working on data centre monitoring or SCADA solutions, and CBSE Class 11-12 learners at ATL Tinkering Labs ready for advanced networking. It also appeals to IIT, NIT, VIT, and BITS electronics enthusiasts exploring OPC-UA and SCADA protocols.
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?
Simply scan the QR code to access the AI build companion, which responds instantly with step-by-step guidance. You can also message us on WhatsApp for human support.
Do I need prior OPC-UA or SCADA experience?
No. The AI companion and step-by-step guide introduce OPC-UA fundamentals in the context of this kit. You'll learn by building and configuring the server from scratch.
Can I integrate this with Siemens S7 or Allen-Bradley PLCs?
The ESP32 OPC-UA server exposes data over TCP/IP, which any OPC-UA client (including Siemens WinCC or Kepware) can access. Direct PLC integration may require an OPC-UA gateway, but this kit demonstrates the complete server side.
Is the kit suitable for a 24/7 production environment?
This is an educational and prototyping tool. While the sensor hardware is reliable, the ESP32 may not meet industrial redundancy requirements. For production, consider industrial-grade OPC-UA servers, but this kit provides the foundational concept.
Data Centre - ESP32 implements OPC-UA server exposing sensor nodes as addressable objects for industrial SCADA.
