You can't turn off the proximity sensor on your iPhone, but if it's malfunctioning, try force-restarting your iPhone and ...

[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 ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

What's behind the target can make a tremendous difference in how well reflective sensors do their job. Consider a photoelectric sensor operating in simple diffused mode (i.e., as a proximity sensor).

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 ...
