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 ...

[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 ...

[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 ...

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 ...

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).

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 ...

A traditional computer mouse typically fits in the palm of your hand. However, with modern technology, there’s no need for mice to be so large, as demonstrated by [juskim]’s neat little mouse ring.

Okay, so that's not a mouse, it is a space-ship isn't it ? Check out the Rat Pro, it allows you to swap sensors to suit your preferences. Mad Catz states that you can switch between sensors in mere ...

LoKast has brought its proximity-based application to Android. Rejoice! Available for the iOther platform since March, LoKast allows you to find, connect and share with other LoKast users in your ...

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 ...

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 ...
