A capacitive proximity sensor can detect only metallic object.

A capacitive proximity sensor can detect only metallic object. Correct Answer False

A capacitive proximity sensor can also detect other object other than just metallic object. It can detect all objects that have a dielectric constant other than air. These type of sensors are widely used in appliances such as track-pads or touch-screen sensors.

Statement (I): To use a sensor, we generally need to add signal conditioning circuitry, such as circuits which amplify and convert from analog to digital, to get the sensor signal in the right form, take account of any non-linearities, and calibrate it.
