Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front-edge ...

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.

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 ...

As long as a magnet can be affixed to the target, the C 12 bi-stable Mag sensor and magnet proximity switches can sense a magnet at distances up to 2" away. The components come with dry contact ...

[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 ...

The following guide provides a review of the types of proximity sensors for prolonged detection, followed by a look at capacitive sensing design specifically for occupancy-type solutions. A variety of ...

Over 340 new products have been added to the PRO factory automation sensors range by RS Components. The range now includes ultrasonic proximity sensors and fibre optical sensors which join the ...

Proximity detection adds many smart features to the devices we use.For example, when making a call with a phone held to your ear, face detection using proximity sensing can disable the touchscreen and ...

An Apple patent application published by the U.S. Patent and Trademark Office on Thursday describes a system that may one day replace the infrared proximity sensors deployed in current iPhones with ...
