[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 ...

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 ...

A device that detects the presence of an object in the vicinity. There are many types of sensors for myriad applications; however, they all work by emitting a signal and analyzing the changes in 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 ...

Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front-edge ...

An Apple invention detailed in a patent application published Thursday describes a method of decoupling a keyboard's mechanical feel from its electrical functionality using proximity sensors, which ...

Vishay’s VCNL4100 is an IR proximity sensor that works up to 1m, and includes an ambient light sensor. Inside, it combines an infra-red (940nm) emitter, photo detectors for proximity and ambient light ...

Smartphone makers are obsessed with making their gear thinner, and Norwegian startup Elliptic Labs has come up with a pretty good way to help. Their answer: get rid of the proximity sensors in our ...

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.

[Dustin Andrews] built this add-on board which works as a proximity sensor. He wanted a standalone sensor for his Arduino projects which would use a single pin as a trigger. This lets him alert the ...
