IoT Communications and Sensors Quiz

Transducers

• Primary function: Convert signals from one physical form to another.
• Example: A microphone converts sound waves into an electrical signal.

Sensors

• MQ-5: Detects gases like LPG, CH4, and CO.
• Resolution: Indicates the smallest change in input that a sensor can detect.

Communication Technologies

• Zigbee: Uses OQPSK modulation technique for the 2.4 GHz band.
• 6LoWPAN: Optimizes packet transmission in Low-power and lossy networks (LLN).
• Z-Wave Network ID: 4 Bytes long.
• Class 1 Bluetooth radios: Typically have a range of 100 meters.
• CoRE Framework: Includes Registration Interface (RI), Resource Directory (RD), and REST based protocols like HTTP and CoAP for service discovery.
• Lifespan policy: Controls the duration for which transmitted data is considered valid in an IoT network.
• MQTT: Supports 3 levels of QoS.
• CoAP: Based on UDP (User Datagram Protocol).

Manufacturing and Industry

• Information and Communication Technology (ICT): Considered the main nervous system of any manufacturing industry.
• Renewable energy consumption: Increases sustainability.
• JIDOKA: Stopping production when there is a problem in Lean Production System.
• Value stream: All actions required for a product from order to delivery.
• 'People Engagement' in Lean production System (L, D, T): Learn, Do, Teach.
• Smart and connected products: Improve the recall process of products.
• Optimization in Smart and Connected Products: Associated with Optimization algorithms.
• Safety in Radioactive Zones (Smart Factory): Augmented Reality can provide safety in radioactive zones.
• Smart Factory Characteristics: Connection, Optimization, Transparent, Proactivity, Agility.
• Industrial Internet: Amalgamation of CPS and the evolution of Internet-based technologies.
• Supply Chain Monitoring: Real-time monitoring reduces inventory and capital requirements.
• Cyber-Physical Systems (CPS): Interacting networks of physical and computational components.
• CPS Computation: Reactive computation.
• CPS-based Manufacturing Systems: Utilize a 5C architecture for design.
• Collaboration Platform (Industry 4.0): A platform used for connecting and sharing information between different systems in a factory.
