Which outcome reduces a capacitive proximity sensor's detection range in humid environments?

A)Increase in dielectric constant
B)Decrease in source frequency
C)Reduce excitation voltage needed
D)Decrease parasitic capacitance effects

💡 Explanation

Increased humidity raises the effective dielectric constant around the sensing plate, flooding the electric fields; because sensor measures changes rather than static fields, this masking reduces detection range, therefore the altered range rather than a recalibration, because recalibration is a separate process altogether.
