  3. IEEE 1451 - Wikipedia

    en.wikipedia.org/wiki/IEEE_1451

    IEEE 1451 is a set of smart transducer interface standards developed by the Institute of Electrical and Electronics Engineers (IEEE) Instrumentation and Measurement Society's Sensor Technology Technical Committee describing a set of open, common, network-independent communication interfaces for connecting transducers (sensors or actuators) to microprocessors, instrumentation systems, and ...

  4. Sensor - Wikipedia

    en.wikipedia.org/wiki/Sensor

    Different types of light sensors. A sensor is a device that produces an output signal for the purpose of detecting a physical phenomenon.. In the broadest definition, a sensor is a device, module, machine, or subsystem that detects events or changes in its environment and sends the information to other electronics, frequently a computer processor.

  5. Transducer - Wikipedia

    en.wikipedia.org/wiki/Transducer

    A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another. [1] Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.).

  6. Smart transducer - Wikipedia

    en.wikipedia.org/wiki/Smart_transducer

    A smart transducer is an analog or digital transducer, actuator, or sensor combined with a processing unit and a communication interface. [ 1 ] As sensors and actuators become more complex, they provide support for various modes of operation and interfacing.

  7. Surface acoustic wave sensor - Wikipedia

    en.wikipedia.org/wiki/Surface_acoustic_wave_sensor

    Surface acoustic wave sensors are a class of microelectromechanical systems (MEMS) which rely on the modulation of surface acoustic waves to sense a physical phenomenon. The sensor transduces an input electrical signal into a mechanical wave which, unlike an electrical signal, can be easily influenced by physical phenomena.

  8. Variable reluctance sensor - Wikipedia

    en.wikipedia.org/wiki/Variable_reluctance_sensor

    A variable reluctance sensor (commonly called a VR sensor) is a transducer that measures changes in magnetic reluctance.When combined with basic electronic circuitry, the sensor detects the change in presence or proximity of ferrous objects.

  9. Ultrasonic transducer - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_transducer

    A curvilinear array ultrasonic transducer for use in medical ultrasonography Inside construction of a Philips C5-2 128 element curved array ultrasound sensor. Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters, receivers and transceivers.
