Modern smartphones are packed with a wide range of sensors, and their magnetometer can successfully identify certain kinds of ...

New MFxM magnetic proximity switches detect magnetic fields over large distances up to 60 mm. These sensors can be used effectively in applications where the target is located behind a wall of ...

Electronic enthusiasts may be interested in a new open source infrared sensor which has been created to support both Raspberry Pi and Arduino powered projects. The IR Detector proximity sensor has ...

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 ...

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 ...

This article was updated and checked for accuracy in April 2024. It was originally published in 2021. Believe it or not, metal detection is actually possible on Android phones. In fact, the first ...

HD Electric Co.’s PRX-500 Proximity Voltage Detector is a new addition to its voltage detector product line. With nine selectable voltage ranges from 120V up to 500kV, the detector features an easy-to ...

Available in two- and three-wire versions, the M12, '18, and '30 inductive proximity sensors detect at ranges of 4 and 8 mm, 8 and 14 mm, and 15 and 22 mm, respectively. Range for a particular sensor ...

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. The PRX provides an audible and visual indication of voltage ...

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.
