Title (EN) CAPACITANCE LIQUID LEVEL SENSOR
(FR) DÉTECTEUR DE NIVEAU DE LIQUIDE DE CAPACITÉ
Abstract:
(EN) In accordance with at least one embodiment, a method for detecting a liquid level includes providing a container (402) having a cavity, and disposing a sensor (102) in the cavity of the container (402), such that a ground pattern (310) on a first surface of the sensor (102) is positioned to contact a liquid in the cavity. A first electrode (104) and a second electrode (106) are located on a second surface of the sensor (102). The sensor (102) is coupled to a sensor input and a sensor driver. A cable coupling the sensor (102) to a touch sensor (116) comprises a shield line (112, 114) that is coupled to ground.
(FR) L'invention concerne, selon au moins un mode de réalisation, un procédé de détection d'un niveau de liquide consistant à utiliser un récipient (402) ayant une cavité, et à disposer un capteur (102) dans la cavité du récipient (402), de sorte qu'un motif de masse (310) sur une première surface du capteur (102) soit positionné pour entrer en contact avec un liquide dans la cavité. Une première électrode (104) et une seconde électrode (106) sont situées sur une seconde surface du capteur (102). Le capteur (102) est couplé à une entrée de capteur et à un pilote de capteur. Un câble couplant le capteur (102) à un capteur tactile (116) comprend une ligne de blindage (112, 114) qui est couplée à la masse.
