Opcua

A client and server implementation of the OPC UA specification written in Rust

Internet of Things (IoT)RustMPL-2.0

Abstract

Opcua is an open-source Internet of Things (IoT) project. A client and server implementation of the OPC UA specification written in Rust. OPC UA is an industry standard for monitoring of data. It's used extensively for embedded devices, industrial control, IoT, etc. It is built using Rust. The complete source code is publicly available on GitHub under the Mozilla Public License 2.0, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.

1. Introduction

OPC UA is an industry standard for monitoring of data. It's used extensively for embedded devices, industrial control, IoT, etc. - just about anything that has data that something else wants to monitor, control or visualize.

Rust is a systems programming language and is therefore a natural choice for implementing OPC UA. This implementation supports the embedded, micro and nano profiles but may grow to support features in time.

Read the compatibility page for how the implementation conforms with the OPC UA spec.

2. Objective

A client and server implementation of the OPC UA specification written in Rust

This project demonstrates how Rust can be applied to a real-world Internet of Things (IoT) problem.

4. Technology Stack

Rust

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

  • Rust toolchain (rustup / cargo)
  • Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/locka99/opcua.git
cd opcua

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

  • Add a mobile dashboard using Blynk or Firebase
  • Store readings in a cloud database for history charts
  • Add alerts via SMS / Telegram when thresholds are crossed

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

  1. Which microcontroller / board and sensors are used and why?
  2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
  3. Where is the sensor data stored and visualised?
  4. How is power consumption managed?
  5. How would you secure the device and its communication?
