It seems like engineering 101, but do you actually remember the specific differences between inductive proximity, inductive displacement, and eddy-current sensors? I asked a few friends and everyone ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

A common application seen throughout the industrial and commercial sectors is proximity sensing—detecting when some object is physically close to a sensor. A variety of processes can be implemented ...
