If you’re an Electrical, Electronics, or E&TC engineering student in Maharashtra and planning your career, one thing is clear—Industrial Automation is changing faster than ever. And right at the center of this transformation is IoT (Internet of Things)
In simple words,IoT connects machines, sensors, and devices so they can communicate and share data. When this power is added to Industrial Automation, industries become smarter, faster, and more efficient
So, why should you learn IoT along with PLC, SCADA, HMI, and other automation tools?
Let’s break it down.
1. IoT is the Heart of Industry 4.0
Modern industries rely on data.
IoT helps collect this data from machines, sensors, VFDs, robots, and PLCs which may be located in different nations in the world”.
When companies analyze this data, they can:
* Predict machine breakdowns
* Reduce downtime
* Improve productivity
* Maintain safety
In short, IoT is what makes automation “smart” automation
2. IoT Skills Give You a Career Edge
Traditional automation knowledge—like PLC programming (Siemens, Allen Bradley, Delta), Ladder Logic, SCADA, and HMI—is essential.
But adding IoT to your skillset makes you more valuable because industries now need engineers who understand:
* Cloud connectivity
* Sensors and embedded boards (Arduino, Raspberry Pi)
* Communication protocols (MQTT, Modbus, OPC-UA)
* Data logging and dashboards
This combination opens the door to high-growth roles.
3. Industries Are Actively Hiring IoT + Automation Engineers
Manufacturing plants in Pune, Nashik, Aurangabad, and Mumbai are upgrading to smart automation. These industries need engineers who can integrate IoT with industrial systems.
Popular job roles include:
| Job Role | What You Do
| —————————————— | ——————————————————
| IoT Automation Engineer | Connect PLCs, sensors, and machines to cloud platforms
| Industrial IoT Analyst | Collect and analyze machine data
| SCADA + IoT Engineer | Build real-time dashboards
| Maintenance Engineer (Smart Factory) | Monitor machines using IoT alerts
| Embedded + Automation Developer | Work with Raspberry Pi/Arduino for automation
4. IoT Makes Automation Projects More Real and Exciting
Imagine creating projects like:
* Monitoring motor vibration using sensors
* Sending machine data to your mobile
* Controlling a PLC system from a dashboard
* Predictive maintenance alerts
* Energy monitoring of a production line
These are industry-level IoT applications—and extremely valuable for placements
5. IoT Helps You Work with Modern PLCs and Systems
Most modern PLCs support IoT features such as:
* MQTT communication
* Edge computing
* Cloud integration
* Remote monitoring
Brands like Siemens, Delta, Allen Bradley, Schneider all offer IoT-enabled controllers.
If you know IoT, you can use the full power of these PLCs.
6. IoT Professionals Get Better Salaries
Companies are willing to pay more because IoT engineers help them:
* Reduce maintenance costs
* Increase machine life
* Improve productivity
* Enable real-time monitoring
A fresher with PLC + SCADA + IoT skills can earn a stronger starting salary than someone with only basic automation knowledge.
7. Learning IoT is Not Difficult—Students Love It!
IoT involves easy-to-learn components like:
* Arduino
* Raspberry Pi
* ESP8266/ESP32
* Basic sensors
* Cloud platforms
Once you understand how data flows, combining IoT with PLC automation becomes fun and practical.
