Capacitive sensors

Capacitive sensors detect changes in electrical charge caused by the presence or absence of an object, typically a conductive or dielectrically different material. They work by generating an electric field and measuring variations in capacitance when an object comes close or touches the sensor. Commonly used in touchscreens, industrial automation, and liquid level detection, these sensors are valued for their sensitivity, speed, and ability to detect non-metallic materials without direct contact. They provide reliable, contactless measurements and can be tailored for various applications by adjusting their sensitivity and design.
