  2. Sensor - Wikipedia

    en.wikipedia.org/wiki/Sensor

    For example, if a sensor measures temperature and has a voltage output, the sensitivity is constant with the units [V/K]. The sensitivity is the slope of the transfer function. Converting the sensor's electrical output (for example V) to the measured units (for example K) requires dividing the electrical output by the slope (or multiplying by ...

  3. Signal conditioning - Wikipedia

    en.wikipedia.org/wiki/Signal_conditioning

    Signal amplification performs two important functions: increases the resolution of the input signal, and increases its signal-to-noise ratio. [citation needed] For example, the output of an electronic temperature sensor, which is probably in the millivolts range is probably too low for an analog-to-digital converter (ADC) to process directly.

  4. List of temperature sensors - Wikipedia

    en.wikipedia.org/wiki/List_of_temperature_sensors

    The integrated circuit sensor may come in a variety of interfaces — analogue or digital; for digital, these could be Serial Peripheral Interface, SMBus/I 2 C or 1-Wire.. In OpenBSD, many of the I 2 C temperature sensors from the below list have been supported and are accessible through the generalised hardware sensors framework [3] since OpenBSD 3.9 (2006), [4] [5]: §6.1 which has also ...

  5. Sensitivity (electronics) - Wikipedia

    en.wikipedia.org/wiki/Sensitivity_(electronics)

    The output signal for an electronic analog sensor is usually a voltage or a current signal . The responsivity of an ideal linear sensor in the absence of noise is defined as R = S o / S i {\textstyle R=S_{o}/S_{i}} , whereas for nonlinear sensors it is defined as the local slope d S o / d S i {\displaystyle \mathrm {d} S_{o}/\mathrm {d} S_{i}} .

  6. Analog-to-digital converter - Wikipedia

    en.wikipedia.org/wiki/Analog-to-digital_converter

    Some radar systems use analog-to-digital converters to convert signal strength to digital values for subsequent signal processing. Many other in situ and remote sensing systems commonly use analogous technology. Many sensors in scientific instruments produce an analog signal; temperature, pressure, pH, light intensity etc. All these signals can ...

  7. Analog signal processing - Wikipedia

    en.wikipedia.org/wiki/Analog_signal_processing

    All systems have some dependence on things like temperature, signal level or other factors that cause them to be non-linear or non-time-invariant, but most are stable enough to model as LTI. Linearity and time-invariance are important because they are the only types of systems that can be easily solved using conventional analog signal ...

  8. Analog signal - Wikipedia

    en.wikipedia.org/wiki/Analog_signal

    An analog signal (American English) or analogue signal (British and Commonwealth English) is any continuous-time signal representing some other quantity, i.e., analogous to another quantity. For example, in an analog audio signal , the instantaneous signal voltage varies continuously with the pressure of the sound waves .

  9. HVAC control system - Wikipedia

    en.wikipedia.org/wiki/HVAC_control_system

    HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. [1] Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the ...
