[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

Position Sensors play an important role in our daily lives. A position sensor, as the name indicates, provides feedback on the position of the measurand by detecting the presence/absence of an object ...

Most design engineers of consumer and industrial products always look for various ways to achieve their desired goals in applications ranging from wearables to handheld devices to industrial ...

Touch-free user interfaces are the new trend for automotive design engineers. There are multiple ways to implement this feature, and one of them is through proximity sensing. Proximity sensing is a ...

Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.

With proximity sensors—proxes—and photoelectric sensors, the question is not only whether to use them, but when and how. For instance, proxes may provide robust solutions because they have no lenses ...

[Editor's note: At the RSA Conference in San Francisco earlier this month, InfoWorld magazine released a video from tech firm IOActive, where the companies tech staff claimed to have been able to ...

A device that senses when another object is close by. In a mobile phone, a proximity sensor is most commonly used to detect when the phone is held to the face. Specifically, the sensor detects human ...
