摘要

Capacitive sensor on the basis of the wool (chorisia speciosa) for the detection of oil in water. The sensor is composed of a capacitor formed of two metal parts parallel to each other, a carpet of wool (chorisia speciosa) is inserted between the metals. The metal plate are arranged in parallel, supported by a support not driver (polymeric) side.A capacitance meter is connected to the plates.Yarn of wool braided form the carpet that is on the inside of the metal plates arranged in parallel and which can provide smooth structure, or a matrix in the form of a grid or a matrix of holes with internal pins, the carpet of wool in contact with water, a pattern But in the presence of oil, absorbs.By changing the capacitance of the system and indicating the presence of oil in water.
