Technology: IoT in Manufacturing Industries (Industrial IoT / IIoT)

IoT in Manufacturing Industries (Industrial IoT / IIoT)

The Industrial Internet of Things (IIoT) refers to the application of IoT technologies in manufacturing, production, and supply chain operations. It enables factories to become smarter, safer, and more efficient through connected sensors, machines, and software.

⚙️ How IoT Works — 4 Key Steps:

Sensors/Devices

Devices collect data (e.g., motion, temperature, heart rate)

Example: Smart thermostat senses room temperature

Connectivity

Devices send this data via the internet (Wi-Fi, 4G/5G, Bluetooth)

Example: Thermostat sends data to a cloud server

Data Processing

Data is processed by cloud systems or edge computing

Example: The Thermostat decides if the temperature needs adjustment

Action/Response

Devices act or alert users based on insights

Example: The Thermostat turns on the AC or sends a notification to your phone

⚙️ How IoT Works in a Factory Setup

Sensors & Devices: Attached to machines, conveyors, motors, or products

Data Collection: Real-time data on temperature, pressure, vibration, energy use, etc.

Connectivity: Data sent to the cloud or edge systems via Wi-Fi, LPWAN, or 5G

Processing & Analytics: AI/ML analyzes trends, predicts failures

Automated Action: Alerts, shutdowns, maintenance requests, or quality adjustments triggered
