[Ivan’s] friend built a proximity sensor to switch his LED bench lighting off every time he walked away. The idea is pretty neat, so [Ivan] decided to implement it for mains devices by making this ...

A common application seen throughout the industrial and commercial sectors is proximity sensing—detecting when some object is physically close to a sensor. A variety of processes can be implemented ...

[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 ...

This application note describes briefly important factors for the usage of the PCF8883 and PCA8886 sensor devices. Sensor devices, or capacitive proximity switches in particular, is always a ...

Distance bounding protocols are essential security measures designed to authenticate the proximity of a user or device to a verifier, thereby preventing relay attacks. Relay attacks occur when an ...

The new Model S46 Microwave Switch System reportedly is the first such system that can be ordered in a wide variety of configurations using an off-the-shelf product. The systems can be built with up ...
