INTERNET OF THINGS- Mechanical Systems

The Internet of Things (IoT) refers to the network of physical objects (or "things") embedded with sensors, software, and other technologies that enable them to connect and exchange data with other devices and systems over the internet. IoT transforms everyday objects into "smart" devices, allowing them to collect, share, and act on data, creating opportunities for automation, efficiency, and innovation across industries.

IoT in Mechanical Systems (with pictures)

1. Smart Manufacturing / Industry 4.0

·         Machines connected with sensors (temperature, vibration, pressure).

·         Data sent to cloud for predictive maintenance.

·         Reduces downtime.

2. HVAC (Heating, Ventilation & Air Conditioning)

·         IoT sensors monitor air flow, temperature, energy usage.

·         Ensures comfort + energy efficiency.

3. Automobile & Mechanical Systems

·         Smart cars use IOT for fuel monitoring, predictive maintenance, tire pressure, and engine health.

·         Connected vehicles exchange data with cloud and other vehicles.

4. Robotics & Automation

·         IOT-enabled robots in factories.

·         Remote monitoring of robot operations via mobile apps.

5. Smart Energy Management in Mechanical Systems

·         IOT-enabled motors, pumps, turbines.

·         Sensors track vibration, torque, energy losses → Prevent failure.

So IoT for Mechanical = Sensors + Connectivity + Cloud/Analytics + Control → Efficient, Smart & Predictive Systems.
