[Dustin Andrews] built this add-on board which works as a proximity sensor. He wanted a standalone sensor for his Arduino projects which would use a single pin as a trigger. This lets him alert the ...

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.

I'm no stranger to losing things. From leaving my bag on a park bench, to sifting through all my coats in the closet just to find the one pocket I last left my keys in, it's common for things to go by ...

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 ...

Non-contact proximity sensors can improve the ruggedness of manufacturing operations, such as metal component assembly, by replacing delicate mechanical switches. Sensor selection for these ...

Most design engineers of consumer and industrial products always look for various ways to achieve their desired goals in applications ranging from wearables to handheld devices to industrial ...

Factory automation environments are currently experiencing a massive surge in the number of sensors deployed. These sensors measure everything from temperature to proximity and weight to pressure, as ...

[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 ...
