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): Capacitive proximity sensor can only be used for the detection of metal objects and is best with ferrous metals. Statement (II): One form of capacitive proximity sensor consists of a single capacitor plate probe with the other plate being formed by the object, which has to be metallic and earthed.
Will an infrared proximity sensor detect a black object when it comes in suitable range?
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. Statement (II): A smart sensor is integrated with the required buffering and conditioning circuitry in a single element and provides functions beyond that of just a sensor.
