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.

[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 ...

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 ...

Properly choosing an inductive proximity sensor can be challenging. Learn about the critical factors to consider when making your decision. Inductive proximity sensors detect the position/presence of ...

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 ...

Like many cats, Leonie loves to explore her surroundings, and after satisfying her curiosity, she likes to return home, where it’s warm and dry and there’s food. Usually somebody will open the outside ...

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 ...

STMicroelectronics' engineer Tom Bocchino explains how the company's TMOS sensor can detect human presence and proximity. STMicroelectronics' TMOS sensors handle presence sensing using a 5- to 20-µm ...

One of the major issues surrounding the iPhone 4 release this summer was the proximity sensor failing during phone calls resulting in muting, conference calling, and other inadvertent touch input.
