Abstract

SENSOR CAPACITIVO E MéTODO DE PRODUçãO. A presente invenção refere-se a um sensor capacitivo que compreende um condutor de sensor com um grande condutor de guarda atrás deste, no qual a sensibilidade para objetos distantes é melhorada pela minimização da área de material condutor que forma o condutor de sensor especificamente em tiras verticais que representam o percurso de água sobre o sensor. A sensibilidade a escorrimentos de água tais como da chuva que fluem sobre o sensor é por meio disto reduzida.CAPACITIVE SENSOR AND PRODUCTION METHOD. The present invention relates to a capacitive sensor comprising a sensor conductor with a large guard conductor behind it, in which the sensitivity to distant objects is improved by minimizing the area of conductive material forming the sensor conductor specifically in strips. vertical lines that represent the water path over the sensor. The sensitivity to water runoff such as rain flowing over the sensor is thereby reduced.
