Capacitive proximity sensors can be used to detect metallic and also nonmetallic targets like paper, wood, plastic, glass, wood, powder, liquid..etc without physical contact. The capacitive proximity sensor works on the capacitor principle. The main components of the capacitive proximity sensor are plate, oscillator, threshold detector, and the output circuit.
