  2. Time constant - Wikipedia

    en.wikipedia.org/wiki/Time_constant

    A time constant is the amount of time it takes for a meteorological sensor to respond to a rapid change in a measure, and until it is measuring values within the accuracy tolerance usually expected of the sensor. This most often applies to measurements of temperature, dew-point temperature, humidity and air pressure.

  3. Response time - Wikipedia

    en.wikipedia.org/wiki/Response_time

    Response time (biology), the elapsed time from the presentation of a sensory stimulus to the completion of the subsequent behavioral response; Response time (technology), the time a generic system or functional unit takes to react to a given input Display response time, the amount of time a pixel in a display takes to change; Round-trip delay ...

  4. Photodetector - Wikipedia

    en.wikipedia.org/wiki/Photodetector

    Response time: The time needed for a photodetector to go from 10% to 90% of final output. Noise spectrum: The intrinsic noise voltage or current as a function of frequency. This can be represented in the form of a noise spectral density. Nonlinearity: The RF-output is limited by the nonlinearity of the photodetector [10]

  5. 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.

  6. Catalytic bead sensor - Wikipedia

    A catalytic bead sensor is a type of sensor that is used for combustible gas detection from the ... up to and beyond 100% LEL, response time is a few seconds to ...

  7. Settling time - Wikipedia

    en.wikipedia.org/wiki/Settling_time

    Settling time depends on the system response and natural frequency. The settling time for a second order , underdamped system responding to a step response can be approximated if the damping ratio ζ ≪ 1 {\displaystyle \zeta \ll 1} by T s = − ln ⁡ ( tolerance fraction ) damping ratio × natural freq {\displaystyle T_{s}=-{\frac {\ln ...

  8. Photodiode - Wikipedia

    en.wikipedia.org/wiki/Photodiode

    Response time The response time is the time required for the detector to respond to an optical input. A photon absorbed by the semiconducting material will generate an electron–hole pair which will in turn start moving in the material under the effect of the electric field and thus generate a current.

  9. Retinomorphic sensor - Wikipedia

    en.wikipedia.org/wiki/Retinomorphic_sensor

    At time t ≥ t 0, the capacitor is under illumination and the capacitance changes to C light, resulting in the charge the plates can accommodate changing. The excess charge then flows on/off of the plates over a period of time determined by the resistor R. There are several retinomorphic sensor designs which yield a similar response.
