Study Notes
Smart Object Capabilities
- Smart object capabilities are categorized into core, enhanced, and advanced types.
- Core capabilities are essential; without them, an object is not considered smart. They include:
- Digital identification
- Retention
- Communication
- Energy harvesting
Core Capabilities
- Communication is crucial for information exchange in IoT networks.
- Smart objects require energy for processing and task execution, sourcing energy from external or autonomous means.
Enhanced Capabilities
- Enhanced capabilities improve the functionality of smart objects and include:
- Sensing/actuating
- Processing
- Networking
- Shielding (ensures security and privacy)
- Logging
Advanced Capabilities
- Advanced capabilities include:
- Self-awareness: tracking status, structure, and history of the object.
- Self-management: utilizing data for life cycle and maintenance management.
Stimuli Classification
- Stimuli measurable by sensors are classified into types:
- Electric Stimuli: Charge, Electric Field, Current, Voltage.
- Magnetic Stimuli: Magnetic Field, Magnetic Flux, Magnetic Flux Density.
- Thermal Stimuli: Temperature, Thermal Conductivity.
- Mechanical Stimuli: Velocity, Position, Acceleration, Force, Density, Pressure.
Sensors and Actuators
- Sensors and actuators work together, with actuators converting electrical signals to non-electrical energy.
- Example actuator: Electric motor, which translates electrical signals into mechanical action.
- Example sensors include light and motion detectors; example actuators include LEDs and motors.
Transducers
- Transducers can convert energy forms; examples are loudspeakers and potentiometers.
Sensor Classifications
- Sensors can be categorized in several ways:
- Simple (Direct) vs. Complex Sensors
- Active vs. Passive Sensors
- Contact vs. Non-Contact Sensors
- Absolute vs. Relative Sensors
- Digital vs. Analog Sensors
- Scalar vs. Vector Sensors
Active and Passive Sensors
- Active sensors (parametric) require external power (e.g., capacitive, inductive sensors).
- Passive sensors (self-generating) generate electrical signals independently (e.g., piezoelectric sensors).
Contact and Non-Contact Sensors
- Contact sensors require physical contact with stimuli (e.g., temperature sensors).
- Non-contact sensors do not require physical contact (e.g., infrared thermometers).
