Vishay Semiconductors has created an interesting reflectance proximity detector (VCNL4000) that includes an infrared (IR) LED and a photodetector. A second sensor in the same package measures ambient ...

Aimed at mobile devices as well as other consumer electronics, the fifth-generation TSL2x72 series digital ambient light sensors (ALS) and proximity detectors are designed to create the widest dynamic ...

WASHINGTON (CN) - The Mine Safety and Health Administration plans to require coal mining operations to equip continuous coal mining machines with proximity sensors to reduce injuries and deaths. A ...

The detector is intended for the recognition of obstructions at distances of a few millimeters to a few centimeters. Similar detectors are used in the industry and health services, for instance, to ...

HDE's PRX-500 Proximity Voltage Detector is a non-contact voltage detector with nine selectable voltage ranges from 120 VAC up to 500 kVAC. March 5, 2012 HDE's PRX-500 Proximity Voltage Detector is a ...

This project is a simple modification of the LightGauge project. Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino.

A lot of the frenzied last minute speculation leading up to this morning’s Apple Tablet announcement is either going to look eerily prescient or downright silly in just a few hours time, but here’s ...

CHARLESTON, W.Va. — Four percent of underground equipment in West Virginia coal mines are fitted with detectors that automatically shut down mobile machinery when people get too close, according to a ...

Training for the placement of unattended ground sensors (UGSs) takes place at Fort Bliss, Texas. Tactical and urban UGSs are both part of Future Combat Systems (FCS) equipment and are scheduled to be ...
