  2. 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.

  4. Chemical sensor array - Wikipedia

    en.wikipedia.org/wiki/Chemical_sensor_array

    A chemical sensor array is a sensor architecture with multiple sensor components that create a pattern for analyte detection from the additive responses of individual sensor components. There exist several types of chemical sensor arrays including electronic, optical, acoustic wave, and potentiometric devices.

  5. Image sensor - Wikipedia

    en.wikipedia.org/wiki/Image_sensor

    An image sensor or imager is a sensor that detects and conveys information used to form an image. It does so by converting the variable attenuation of light waves (as they pass through or reflect off objects) into signals , small bursts of current that convey the information.

  6. Transducer - Wikipedia

    en.wikipedia.org/wiki/Transducer

    A sensor is a transducer that receives and responds to a signal or stimulus from a physical system. [3] [4] [2] It produces a signal, which represents information about the system, which is used by some type of telemetry, information or control system. An actuator is a device that is responsible for moving or controlling a mechanism or system.

  7. Sensor array - Wikipedia

    en.wikipedia.org/wiki/Sensor_array

    A sensor array is a group of sensors, usually deployed in a certain geometry pattern, used for collecting and processing electromagnetic or acoustic signals. The advantage of using a sensor array over using a single sensor lies in the fact that an array adds new dimensions to the observation, helping to estimate more parameters and improve the estimation performance.

  8. 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.

  9. Electro-optical sensor - Wikipedia

    en.wikipedia.org/wiki/Electro-optical_sensor

    An optical sensor converts light rays into electronic signals. It measures the physical quantity of light and then translates it into a form readable by an instrument. An optical sensor is generally part of a larger system that integrates a source of light, a measuring device, and the optical sensor. This is often connected to an electrical ...
