Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

Zero Humidity Capacitance (pF) (pF)

Required number input.

Sensitivity (pF/%) (pF/%)

Required number input.

Relative Humidity (%) (%)

Required number input.

Calculate a linear humidity sensor's capacitance from its calibrated zero-RH capacitance and sensitivity per percentage point of relative humidity. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Capacitance (pF) (pF)

The resulting capacitance (pf) returned as a number.

• Sensor output and accuracy calculations depend on excitation, transfer function, reference conditions, loading, calibration, temperature, hysteresis, nonlinearity, bandwidth, cross-sensitivity, and long-term drift. A nominal sensitivity does not establish measurement uncertainty.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• Pressure Sensor Voltage Output

  Calculate a calibrated linear pressure sensor's output voltage from zero-pressure voltage, sensitivity per kilopascal, and applied pressure.

• Current Sensor Output Voltage

  Calculate linear current-sensor output voltage from zero-current offset, volts-per-ampere sensitivity, and signed current.

• Accelerometer Voltage Output

  Calculate linear analog accelerometer voltage from zero-g voltage, sensitivity in volts per g, and signed acceleration in g.
