Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

Capacitive touch sensing is a popular alternative to mechanical switches and knobs in consumer electronics, white goods, and automotive applications. In traditional designs, capacitive touch sensing ...

Capacitive sensor interfaces are critical to the accurate measurement of physical parameters such as pressure, humidity, and force across a broad range of applications including biomedical devices ...

While viable cell density (VCD) monitoring using capacitance sensors is already well-established and aligned with Process ...

The following guide provides a review of the types of proximity sensors for prolonged detection, followed by a look at capacitive sensing design specifically for occupancy-type solutions. A variety of ...

Capacitive proximity sensor block diagram Capacitive proximity sensors use two metal electrodes or plates to generate a high-frequency electrostatic field.

Most capacitance sensors have a single probe that measure capacitance to a grounded target. However this technique suffers from high thermal drift, typically in the order of 1 µm.K-1 for a sensor with ...

Capacitive sensors, on the other hand, can be isolated from the water itself, and thus sense the levels without being subject to such degradation.

The capacitance-type pressure sensor is generally characterized by high sensitivity and low current consumption and this product also minimizes the influence of temperature changes on pressure ...

Capacitive touch sensors are entirely in the domain of DIY, requiring little more than a carefully-chosen conductive surface and a microcontroller. This led [John Phillips] to ask why not embed ...
