Proximity sensors, which are designed to detect the presence of nearby objects without any physical contact, have evolved from narrow application in industrial automation systems into broad use. They ...

[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 ...

Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, automation, and industrial processes, where ...

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 ...

Omron Automation has added more than 2500 devices to its E2E NEXT line of proximity sensors featuring extended sensing distance and IoT functionality. Long-distance sensing minimizes target contact ...

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 ...

Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.
